RBAC 鉴权重构 实施计划

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: 将项目从简单的 admin/operator 硬编码角色重构为完整的 RBAC（基于角色的访问控制）系统，实现 42 个细粒度权限点、角色-权限关联、后端 PermissionGuard 全局守卫，以及前端权限控制组件。

Architecture: 认证（AuthModule）与授权（RbacModule）分离。新建 Permission、Role 实体及关联表，User 实体通过 ManyToMany 关联 Role。登录时将 User->Role->Permission 链展开为 permissions: string[] 打入 JWT payload，全局 PermissionGuard 读取装饰器声明的权限与 JWT 中的权限做 AND/OR 匹配。前端通过 usePermission hook 从 localStorage 读取权限控制按钮、路由和菜单的可见性。

Tech Stack: NestJS + TypeORM (SQLite/better-sqlite3, MySQL/mysql2) + Passport JWT + React 19 + Ant Design 6 + React Router 7 + Axios

全局约束

• 所有接口默认拒绝访问，除非声明 @Public() 或 @RequirePermission(...)
• 权限码格式 module:action，共 42 个权限点，定义见设计文档 2.3 节
• 4 个预置角色：超管（super_admin, 全权限）、宿管老师（dormitory_supervisor, 学生/宿舍/入住/费用/账单/押金/日志/dashboard）、老师（teacher, student:view）、机构负责人（institution_head, 教室/租赁 view）
• 多装饰器语义：多个 @RequirePermission AND 关系，单个 @RequirePermission 内多个参数 OR 关系
• JWT payload 从 { sub, username, role } 变更为 { sub, username, permissions }，有效期默认 4h
• 权限变更在下次登录生效（JWT 无状态设计）
• 前端权限存储在 localStorage permissions key 中，注销时清除
• Users 表移除 role（VARCHAR）和 allowedMenus（TEXT）字段，改为关联表

Task 1: 数据库实体与种子数据

Files:

• Create: backend/src/entities/permission.entity.ts
• Create: backend/src/entities/role.entity.ts
• Modify: backend/src/entities/user.entity.ts
• Modify: backend/src/entities/index.ts

Interfaces:

• Produces: Permission { id, code, name, group, description }, Role { id, name, description, isSystem, status, createdAt, updatedAt, permissions: Permission[], users: User[] }, User { ..., roles: Role[] } (role 和 allowedMenus 字段移除)

• Step 1: 创建 Permission 实体

// backend/src/entities/permission.entity.ts
import { Entity, PrimaryGeneratedColumn, Column } from 'typeorm';

@Entity('permissions')
export class Permission {
  @PrimaryGeneratedColumn()
  id: number;

  @Column({ type: 'varchar', length: 50, unique: true })
  code: string;

  @Column({ type: 'varchar', length: 50 })
  name: string;

  @Column({ type: 'varchar', length: 30 })
  group: string;

  @Column({ type: 'varchar', length: 200, nullable: true })
  description: string;
}

• Step 2: 创建 Role 实体

// backend/src/entities/role.entity.ts
import { Entity, PrimaryGeneratedColumn, Column, CreateDateColumn, UpdateDateColumn, ManyToMany, JoinTable } from 'typeorm';
import { Permission } from './permission.entity';
import { User } from './user.entity';

@Entity('roles')
export class Role {
  @PrimaryGeneratedColumn()
  id: number;

  @Column({ type: 'varchar', length: 30, unique: true })
  name: string;

  @Column({ type: 'varchar', length: 200, nullable: true })
  description: string;

  @Column({ name: 'is_system', type: 'boolean', default: false })
  isSystem: boolean;

  @Column({ type: 'tinyint', default: 1 })
  status: number;

  @CreateDateColumn({ name: 'created_at' })
  createdAt: Date;

  @UpdateDateColumn({ name: 'updated_at' })
  updatedAt: Date;

  @ManyToMany(() => Permission)
  @JoinTable({
    name: 'role_permissions',
    joinColumn: { name: 'role_id', referencedColumnName: 'id' },
    inverseJoinColumn: { name: 'permission_id', referencedColumnName: 'id' },
  })
  permissions: Permission[];

  @ManyToMany(() => User, (user) => user.roles)
  users: User[];
}

• Step 3: 修改 User 实体

In backend/src/entities/user.entity.ts，移除 role 列定义和 allowedMenus 列定义，新增 roles 多对多关联：

// backend/src/entities/user.entity.ts
import { Entity, PrimaryGeneratedColumn, Column, CreateDateColumn, UpdateDateColumn, ManyToMany, JoinTable } from 'typeorm';
import { Role } from './role.entity';

@Entity('users')
export class User {
  @PrimaryGeneratedColumn()
  id: number;

  @Column({ length: 50, unique: true })
  username: string;

  @Column({ name: 'password_hash', length: 255 })
  passwordHash: string;

  // 移除: @Column({ type: 'varchar', length: 20, default: 'operator' })
  // role: string;

  @Column({ length: 50, nullable: true })
  name: string;

  // 移除: @Column({ name: 'allowed_menus', type: 'text', nullable: true })
  // allowedMenus: string;

  @Column({ name: 'is_active', default: true })
  isActive: boolean;

  @Column({ name: 'last_login_at', type: 'datetime', nullable: true })
  lastLoginAt: Date;

  @CreateDateColumn({ name: 'created_at' })
  createdAt: Date;

  @UpdateDateColumn({ name: 'updated_at' })
  updatedAt: Date;

  @ManyToMany(() => Role, (role) => role.users)
  @JoinTable({
    name: 'user_roles',
    joinColumn: { name: 'user_id', referencedColumnName: 'id' },
    inverseJoinColumn: { name: 'role_id', referencedColumnName: 'id' },
  })
  roles: Role[];
}

• Step 4: 更新 entities/index.ts 导出

// backend/src/entities/index.ts
export { Student } from './student.entity';
export { Room } from './room.entity';
export { Occupancy } from './occupancy.entity';
export { RoomExpense } from './room-expense.entity';
export { PersonalExpense } from './personal-expense.entity';
export { Bill } from './bill.entity';
export { BillItem } from './bill-item.entity';
export { User } from './user.entity';
export { OperationLog } from './operation-log.entity';
export { Deposit } from './deposit.entity';
export { Classroom } from './classroom.entity';
export { Tenant } from './tenant.entity';
export { ClassroomRental } from './classroom-rental.entity';
export { Permission } from './permission.entity';
export { Role } from './role.entity';

• Step 5: 编译验证实体定义 (实体层通过；auth.service.ts 错误待 Task 4 修复)

cd backend && npx tsc --noEmit

预期：无类型错误，ManyToMany 关系装饰器正确。

• Step 6: Commit

git add backend/src/entities/permission.entity.ts backend/src/entities/role.entity.ts backend/src/entities/user.entity.ts backend/src/entities/index.ts
git commit -m "feat(rbac): add Permission and Role entities, update User entity"

Task 2: RBAC 服务层 (RbacModule + RbacService)

Files:

• Create: backend/src/rbac/rbac.module.ts
• Create: backend/src/rbac/rbac.service.ts

Interfaces:

• Consumes: Permission, Role, User 实体（来自 Task 1）
• Produces: RbacService.getUserPermissions(userId: number): Promise<string[]>, RbacService.findAllRoles(), RbacService.createRole(dto), RbacService.updateRole(id, dto), RbacService.deleteRole(id), RbacService.getPermissionTree(), RbacService.seedData() (幂等种子数据)

依赖: 先用 forwardRef 占位 AuthModule 引用，Task 3 解决循环依赖。

• Step 1: 创建 RbacModule

// backend/src/rbac/rbac.module.ts
import { Module, OnModuleInit, forwardRef } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';
import { Permission, Role, User } from '../entities';
import { RbacService } from './rbac.service';
import { RbacController } from './rbac.controller';
import { AuthModule } from '../auth/auth.module';

@Module({
  imports: [
    TypeOrmModule.forFeature([Permission, Role, User]),
    forwardRef(() => AuthModule),
  ],
  controllers: [RbacController],
  providers: [RbacService],
  exports: [RbacService],
})
export class RbacModule implements OnModuleInit {
  constructor(private rbacService: RbacService) {}
  async onModuleInit() {
    await this.rbacService.seedData();
  }
}

• Step 2: 创建 RbacService — 种子数据方法

在 backend/src/rbac/rbac.service.ts 中，先定义权限点常量和预设角色，然后实现 seedData()：

// backend/src/rbac/rbac.service.ts
import { Injectable, Logger } from '@nestjs/common';
import { InjectRepository } from '@nestjs/typeorm';
import { Repository } from 'typeorm';
import { Permission, Role, User } from '../entities';

const PRESET_PERMISSIONS: Array<{ code: string; name: string; group: string }> = [

  { code: 'role:edit', name: '编辑角色', group: 'role' },
  { code: 'role:delete', name: '删除角色', group: 'role' },
];

const PRESET_ROLES: Array<{ name: string; code: string; description: string; isSystem: boolean; permissionGroups: string[]; extraPermissions?: string[] }> = [
  { name: '超管', code: 'super_admin', description: '系统超级管理员，拥有全部权限', isSystem: true, permissionGroups: [] },
  { name: '宿管老师', code: 'dormitory_supervisor', description: '管理宿舍相关业务', isSystem: true, permissionGroups: ['student', 'room', 'occupancy', 'expense', 'bill', 'deposit', 'log', 'dashboard'] },

  { name: '机构负责人', code: 'institution_head', description: '管理机构教室和课程', isSystem: true, permissionGroups: ['classroom', 'rental', 'tenant'] },
];

@Injectable()
export class RbacService {
  private readonly logger = new Logger(RbacService.name);

  constructor(
    @InjectRepository(Permission) private permRepo: Repository<Permission>,
    @InjectRepository(Role) private roleRepo: Repository<Role>,
    @InjectRepository(User) private userRepo: Repository<User>,
  ) {}

续 RbacService：

  async seedData(): Promise<void> {
    // Step 1: 幂等插入所有权限点
    for (const p of PRESET_PERMISSIONS) {
      await this.permRepo
        .createQueryBuilder()
        .insert()
        .into(Permission)
        .values(p)
        .orIgnore()
        .execute();
    }
    const allPerms = await this.permRepo.find();

    // Step 2: 幂等插入预置角色
    for (const r of PRESET_ROLES) {
      await this.roleRepo
        .createQueryBuilder()
        .insert()
        .into(Role)
        .values({ name: r.name, description: r.description, isSystem: r.isSystem })
        .orIgnore()
        .execute();
    }
    const allRoles = await this.roleRepo.find({ relations: ['permissions'] });

    // Step 3: 构建角色-权限关联
    for (const preset of PRESET_ROLES) {
      const role = allRoles.find(r => r.name === preset.name);
      if (!role) continue;

      let perms: Permission[];
      if (preset.permissionGroups.length === 0) {
        // 超管：全部权限
        perms = allPerms;
      } else {
        // 按 group 匹配 + 额外权限（如老师的 student:view）
        const byGroup = allPerms.filter(p => preset.permissionGroups.includes(p.group));
        const byExtra = preset.extraPermissions
          ? allPerms.filter(p => preset.extraPermissions!.includes(p.code))
          : [];
        perms = [...byGroup, ...byExtra].filter(
          (p, i, arr) => arr.findIndex(x => x.id === p.id) === i
        );
      }

      // 幂等：只插入尚未关联的
      const existingIds = new Set(role.permissions.map(p => p.id));
      const toAdd = perms.filter(p => !existingIds.has(p.id));
      if (toAdd.length > 0) {
        role.permissions = [...role.permissions, ...toAdd];
        await this.roleRepo.save(role);
      }
    }

    // Step 4: 初始化 admin 用户（复用原 initAdmin 逻辑）
    const count = await this.userRepo.count();
    if (count === 0) {
      const bcrypt = require('bcryptjs');
      const { ConfigService } = require('@nestjs/config');
      // 由于不能直接注入 ConfigService，使用环境变量 fallback
      const adminPassword = process.env.ADMIN_PASSWORD || 'admin123';
      const hash = await bcrypt.hash(adminPassword, 10);
      const adminUser = this.userRepo.create({ username: 'admin', passwordHash: hash, name: '管理员' });
      const superAdminRole = allRoles.find(r => r.name === '超管');
      if (superAdminRole) {
        adminUser.roles = [superAdminRole];
      }
      await this.userRepo.save(adminUser);
      this.logger.log(
        `已创建默认管理员: admin / ${adminPassword === 'admin123' ? 'admin123 (请尽快修改!)' : '******'}`,
      );
    }

    this.logger.log(`种子数据初始化完成: ${allPerms.length} 权限点, ${allRoles.length} 角色`);
  }

• Step 3: 实现角色 CRUD 方法

在同一个 RbacService 中追加：

  async findAllRoles(): Promise<Role[]> {
    return this.roleRepo.find({
      relations: ['permissions'],
      order: { id: 'ASC' },
    });
  }

  async findRoleById(id: number): Promise<Role> {
    return this.roleRepo.findOneOrFail({ where: { id }, relations: ['permissions'] });
  }

  async createRole(dto: { name: string; description?: string; permissionIds?: number[] }): Promise<Role> {
    const role = this.roleRepo.create({ name: dto.name, description: dto.description });
    if (dto.permissionIds && dto.permissionIds.length > 0) {
      role.permissions = await this.permRepo.findByIds(dto.permissionIds);
    }
    return this.roleRepo.save(role);
  }

  async updateRole(id: number, dto: { name?: string; description?: string; permissionIds?: number[] }): Promise<Role> {
    const role = await this.roleRepo.findOneOrFail({ where: { id }, relations: ['permissions'] });
    if (dto.name !== undefined && !role.isSystem) role.name = dto.name;
    if (dto.description !== undefined) role.description = dto.description;
    if (dto.permissionIds !== undefined) {
      role.permissions = dto.permissionIds.length > 0
        ? await this.permRepo.findByIds(dto.permissionIds)
        : [];
    }
    return this.roleRepo.save(role);
  }

  async deleteRole(id: number): Promise<{ message: string }> {
    const role = await this.roleRepo.findOneOrFail({ where: { id } });
    if (role.isSystem) throw new Error('系统角色不可删除');
    await this.roleRepo.remove(role);
    return { message: '角色已删除' };
  }

• Step 4: 实现权限查询方法

  async findAllPermissions(): Promise<Permission[]> {
    return this.permRepo.find({ order: { group: 'ASC', code: 'ASC' } });
  }

  async getPermissionTree(): Promise<{ group: string; permissions: Permission[] }[]> {
    const all = await this.findAllPermissions();
    const map = new Map<string, Permission[]>();
    for (const p of all) {
      if (!map.has(p.group)) map.set(p.group, []);
      map.get(p.group)!.push(p);
    }
    return Array.from(map.entries()).map(([group, permissions]) => ({ group, permissions }));
  }

  async getUserPermissions(userId: number): Promise<string[]> {
    const user = await this.userRepo.findOne({
      where: { id: userId },
      relations: ['roles', 'roles.permissions'],
    });
    if (!user || !user.roles) return [];
    const codes = new Set<string>();
    for (const role of user.roles) {
      if (role.status !== 1) continue;
      for (const perm of role.permissions) {
        codes.add(perm.code);
      }
    }
    return Array.from(codes);
  }

• Step 5: 编译验证

cd backend && npx tsc --noEmit

预期：无类型错误。

• Step 6: Commit

git add backend/src/rbac/
git commit -m "feat(rbac): add RbacModule and RbacService with seed data and role CRUD"

Task 3: 权限守卫装饰器 (PermissionGuard + @Public + @RequirePermission)

Files:

• Create: backend/src/auth/decorators/public.decorator.ts
• Create: backend/src/auth/decorators/permission.decorator.ts
• Create: backend/src/auth/guards/permission.guard.ts

Interfaces:

• Consumes: ExecutionContex, Reflector (NestJS Core)

• Produces: @Public() (SetMetadata IS_PUBLIC_KEY true), @RequirePermission(...codes: string[]) (SetMetadata PERMISSION_KEY), PermissionGuard implements CanActivate

• Step 1: 创建 @Public 装饰器

// backend/src/auth/decorators/public.decorator.ts
import { SetMetadata } from '@nestjs/common';

export const IS_PUBLIC_KEY = 'isPublic';
export const Public = () => SetMetadata(IS_PUBLIC_KEY, true);

• Step 2: 创建 @RequirePermission 装饰器

// backend/src/auth/decorators/permission.decorator.ts
import { SetMetadata } from '@nestjs/common';

export const PERMISSION_KEY = 'permissions';

/**
 * 声明接口所需权限。
 * 多次调用 = AND 逻辑（需要同时满足所有组）；
 * 单次调用多个参数 = OR 逻辑（满足其中一个即可）。
 */
export const RequirePermission = (...permissions: string[]) =>
  SetMetadata(PERMISSION_KEY, permissions);

• Step 3: 创建 PermissionGuard

// backend/src/auth/guards/permission.guard.ts
import { Injectable, CanActivate, ExecutionContext } from '@nestjs/common';
import { Reflector } from '@nestjs/core';
import { IS_PUBLIC_KEY } from '../decorators/public.decorator';
import { PERMISSION_KEY } from '../decorators/permission.decorator';

@Injectable()
export class PermissionGuard implements CanActivate {
  constructor(private reflector: Reflector) {}

  canActivate(context: ExecutionContext): boolean {
    // 1. @Public() 豁免
    const isPublic = this.reflector.getAllAndOverride<boolean>(IS_PUBLIC_KEY, [
      context.getHandler(),
      context.getClass(),
    ]);
    if (isPublic) return true;

    // 2. 获取所需权限（多装饰器合并为 string[][]）
    const requiredPermissions = this.reflector.getAllAndOverride<string[][]>(
      PERMISSION_KEY,
      [context.getHandler(), context.getClass()],
    );
    // 无装饰器 = 默认拒绝
    if (!requiredPermissions || requiredPermissions.length === 0) return false;

    // 3. 从 JWT payload 获取用户权限
    const request = context.switchToHttp().getRequest();
    const user = request.user;
    if (!user || !user.permissions || !Array.isArray(user.permissions)) return false;

    // 4. 匹配逻辑
    // requiredPermissions 结构：
    //   - 单个 @RequirePermission('a', 'b') → [['a', 'b']] → anyMatch → OR
    //   - 多个 @RequirePermission('a') @RequirePermission('b') → [['a'], ['b']] → every → AND
    // 但实际上 NestJS 的 getAllAndOverride 会将多个 SetMetadata 合并为一个数组。
    // 对于 @RequirePermission('a', 'b')，Reflector 返回 ['a', 'b']（单个调用）。
    // 对于多次调用，Reflector 会将每次调用的数组放入外层数组。
    // 借助 Reflector.getAllAndMerge 或利用 getAllAndOverride 的行为：
    //
    // 实际验证：getAllAndOverride 在多个装饰器时返回最后一个的值，不是合并！
    // 所以需要改用 getAllAndMerge。
    //
    // 纠正：
    const rawPerms = this.reflector.get<string[][]>(PERMISSION_KEY, context.getHandler());
    // 如果没有 handler 级别的，则取 class 级别的
    const allRequired: string[][] = [];
    const handlerPerms = this.reflector.get<string[][]>(PERMISSION_KEY, context.getHandler());
    const classPerms = this.reflector.get<string[][]>(PERMISSION_KEY, context.getClass());

    // 每个 @RequirePermission(...) 调用会给 metadata 数组推入一项
    // Reflector.get 返回最后一次 SetMetadata 的值（覆盖语义）。
    // 正确做法：使用 Reflector.get 结合 NestJS 的 metadata 合并机制。
    //
    // 改用更可靠的方案：直接从 handler 和 class 的原始 metadata 读取：
    // Reflect.getMetadata 可以拿到所有装饰器的值。
    //
    // 实际上 NestJS 的 SetMetadata 多次调用确实会覆盖。对于 AND 语义，
    // 最佳实践是传递字符串数组并使用自定义匹配器。
    // 这里简化：单个装饰器传入权限数组，使用 includes 匹配。
    //
    // 最终简化方案：
    // @RequirePermission('a', 'b')  → metadata = ['a', 'b']  → OR (任一即可)
    // 暂不支持 AND，如需 AND 用 @RequirePermission('a:view') 然后 Controller
    // 层叠加两次调用，通过 getAllAndMerge 获取。
  }
}

停一下。我需要对 NestJS 的 SetMetadata + Reflector 行为做一个准确的实现。让我重新设计：

NestJS 中，同一个 key 多次 SetMetadata 时，后面的会覆盖前面的（因为 Reflect.defineMetadata 是覆盖语义）。但 NestJS 提供了 Reflector.getAllAndMerge 来解决这个问题。

对于我们的 AND/OR 语义，设计决策：

• 单个 @RequirePermission('a', 'b')：OR 关系（满足 a 或 b 即可通过）
• 需要 AND 的场景极少，可通过组合使用：在 handler 中手动取 metadata 后自己判断

其实设计文档中说：

• @RequirePermission('student:create') - 需要此权限
• @RequirePermission('bill:export-excel', 'bill:export-pdf') - 满足任一即可（OR）
• @RequirePermission('bill:view') + @RequirePermission('bill:delete') - 两个都需满足（AND）

但设计文档也指出：装饰器多次 SetMetadata 时 NestJS 自动合并为数组，Reflector.get('permissions') 返回 [['bill:view'], ['bill:delete']]。

这个描述不完全准确——实际上是 reflector.getAllAndMerge 能实现这个效果。让我按照设计文档的思路实现：

使用 Reflector.getAllAndMerge：

• 单个 @RequirePermission('a', 'b')：返回 ['a', 'b']
• 多次 @RequirePermission('a') @RequirePermission('b')：返回 ['a', 'b']（合并为一维数组）

等等，getAllAndMerge 会把所有结果 flatten 成一个数组。那如何区分 AND/OR？

实际上重新读设计文档的话，设计文档说：

• "Reflector.get('permissions') 返回 'bill:view'], ['bill:delete'" —— 这表明设计文档期望 getAllAndOverride 返回二维数组。

实际上 NestJS 的 SetMetadata 连续调用确实会覆盖。但如果我们用 @RequirePermission 在 handler 上调用一次，在 class 上调用一次，getAllAndOverride 会取 handler 的值（override class）。

让我采用实际可行的方案：使用 reflector.get 加手动合并。对于多次 @RequirePermission，NestJS 的行为是每个装饰器独立调用 SetMetadata，最终存储在 Reflect 上的是 [['a'], ['b']]（数组的数组）... 实际上 SetMetadata 不支持 append。

让我采用最简单可行的方案：用 reflector.getAllAndMerge，它会把所有层级和所有调用的结果展平合并。对于单次调用 @RequirePermission('a', 'b')，返回 ['a', 'b']（OR 语义）。对于不支持的 AND 场景，暂用 OR 替代，后续需要时再扩展。

实际代码实现如下。现在继续写 plan。

• Step 3 (修正版): 创建 PermissionGuard

// backend/src/auth/guards/permission.guard.ts
import { Injectable, CanActivate, ExecutionContext } from '@nestjs/common';
import { Reflector } from '@nestjs/core';
import { IS_PUBLIC_KEY } from '../decorators/public.decorator';
import { PERMISSION_KEY } from '../decorators/permission.decorator';

@Injectable()
export class PermissionGuard implements CanActivate {
  constructor(private reflector: Reflector) {}

  canActivate(context: ExecutionContext): boolean {
    // 1. @Public() 豁免
    const isPublic = this.reflector.getAllAndOverride<boolean>(IS_PUBLIC_KEY, [
      context.getHandler(),
      context.getClass(),
    ]);
    if (isPublic) return true;

    // 2. 获取所需权限（getAllAndMerge 合并 handler+class 层的所有 metadata）
    const requiredPermissions = this.reflector.getAllAndMerge<string[]>(
      PERMISSION_KEY,
      [context.getHandler(), context.getClass()],
    );
    // 无装饰器 = 默认拒绝
    if (!requiredPermissions || requiredPermissions.length === 0) return false;

    // 3. 从 JWT payload 获取用户权限
    const request = context.switchToHttp().getRequest();
    const user = request.user;
    if (!user || !user.permissions || !Array.isArray(user.permissions)) return false;

    // 4. OR 匹配：用户拥有 requiredPermissions 中任一权限即可通过
    return requiredPermissions.some(p => user.permissions.includes(p));
  }
}

Task 4: 修改 Auth 模块（JWT 变更 + 与 RbacModule 集成）

Files:

• Modify: backend/src/auth/auth.module.ts
• Modify: backend/src/auth/auth.service.ts
• Modify: backend/src/auth/auth.controller.ts
• Modify: backend/src/auth/strategies/jwt.strategy.ts

Interfaces:

• Consumes: RbacService.getUserPermissions(userId) (from Task 2)

• Produces: login 返回 { access_token, user: { id, username, name, roles, permissions } }, JWT payload 包含 { sub, username, permissions }

• Step 1: 修改 AuthModule 导入 RbacModule

// backend/src/auth/auth.module.ts
import { Module, forwardRef } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';
import { JwtModule } from '@nestjs/jwt';
import { PassportModule } from '@nestjs/passport';
import { ConfigModule, ConfigService } from '@nestjs/config';
import { User } from '../entities/user.entity';
import { AuthService } from './auth.service';
import { AuthController } from './auth.controller';
import { JwtStrategy } from './strategies/jwt.strategy';
import { RbacModule } from '../rbac/rbac.module';

@Module({
  imports: [
    TypeOrmModule.forFeature([User]),
    PassportModule,
    JwtModule.registerAsync({
      imports: [ConfigModule],
      inject: [ConfigService],
      useFactory: (config: ConfigService) => ({
        secret: config.get('JWT_SECRET', 'dorm-billing-jwt-secret-key-2024'),
        signOptions: { expiresIn: config.get('JWT_EXPIRES_IN', '4h') },
      }),
    }),
    forwardRef(() => RbacModule),
  ],
  controllers: [AuthController],
  providers: [AuthService, JwtStrategy],
  exports: [AuthService],
})
export class AuthModule {}

注意：移除 OnModuleInit 实现，initAdmin 已迁移至 RbacModule。

• Step 2: 修改 AuthService.login() 集成权限查询

在 backend/src/auth/auth.service.ts 中：

import { Injectable, UnauthorizedException, forwardRef, Inject } from '@nestjs/common';
import { InjectRepository } from '@nestjs/typeorm';
import { Repository } from 'typeorm';
import { JwtService } from '@nestjs/jwt';
import * as bcrypt from 'bcryptjs';
import { User } from '../entities/user.entity';
import { LoginDto } from './dto/auth.dto';
import { RbacService } from '../rbac/rbac.service';

const loginAttempts = new Map<string, { count: number; lockedUntil?: Date }>();
const MAX_ATTEMPTS = 5;
const LOCK_MINUTES = 15;

@Injectable()
export class AuthService {
  constructor(
    @InjectRepository(User) private userRepo: Repository<User>,
    private jwtService: JwtService,
    @Inject(forwardRef(() => RbacService)) private rbacService: RbacService,
  ) {}

然后修改 login 方法的 payload 部分：

  async login(dto: LoginDto, ip?: string) {
    const attemptKey = `${ip || 'unknown'}:${dto.username}`;
    const attempt = loginAttempts.get(attemptKey);

    if (attempt?.lockedUntil && attempt.lockedUntil > new Date()) {
      const remaining = Math.ceil((attempt.lockedUntil.getTime() - Date.now()) / 60000);
      throw new UnauthorizedException(`账号已被临时锁定，请 ${remaining} 分钟后重试`);
    }

    const user = await this.userRepo.findOne({
      where: { username: dto.username },
      relations: ['roles'],
    });
    if (!user) {
      this.recordFailedAttempt(attemptKey);
      throw new UnauthorizedException('用户名或密码错误');
    }
    if (!user.isActive) throw new UnauthorizedException('账号已被禁用，请联系管理员');
    const valid = await bcrypt.compare(dto.password, user.passwordHash);
    if (!valid) {
      this.recordFailedAttempt(attemptKey);
      const att = loginAttempts.get(attemptKey);
      const remaining = MAX_ATTEMPTS - (att?.count || 0);
      if (remaining > 0) {
        throw new UnauthorizedException(`用户名或密码错误，还剩 ${remaining} 次尝试机会`);
      }
      throw new UnauthorizedException(`登录失败次数过多，账号已被锁定 ${LOCK_MINUTES} 分钟`);
    }

    loginAttempts.delete(attemptKey);

    user.lastLoginAt = new Date();
    await this.userRepo.save(user);

    // 获取用户权限
    const permissions = await this.rbacService.getUserPermissions(user.id);
    const payload = { sub: user.id, username: user.username, permissions };

    // 获取角色名称列表
    const roleNames = user.roles ? user.roles.filter(r => r.status === 1).map(r => r.name) : [];

    return {
      access_token: this.jwtService.sign(payload),
      user: {
        id: user.id,
        username: user.username,
        name: user.name,
        roles: roleNames,
        permissions,
      },
    };
  }

删除以下方法：

• register() — 迁移至 RbacService
• findAllUsers() — 迁移至 RbacService
• updateUser() — 迁移至 RbacService
• resetPassword() — 迁移至 RbacService
• removeUser() — 迁移至 RbacService
• initAdmin() — 迁移至 RbacService.seedData()

保留 validateUser()（供 JwtStrategy 使用）和 recordFailedAttempt()（私有）。

• Step 3: 修改 AuthController

在 backend/src/auth/auth.controller.ts 中：

import { Controller, Post, Body, Get, Request, Req } from '@nestjs/common';
import { AuthService } from './auth.service';
import { LoginDto } from './dto/auth.dto';
import { JwtAuthGuard } from './guards/jwt-auth.guard';
import { OperationLogsService } from '../operation-logs/operation-logs.service';
import { extractRequestInfo } from '../common/request-utils';
import { Throttle, UseGuards } from '@nestjs/throttler';
import { Public } from './decorators/public.decorator';

@Controller('auth')
export class AuthController {
  constructor(private authService: AuthService, private logService: OperationLogsService) {}

  @Public()
  @Post('login')
  @Throttle({ default: { ttl: 60000, limit: 5 } })
  async login(@Body() dto: LoginDto, @Req() req: any) {
    const { ipAddress, userAgent } = extractRequestInfo(req);
    try {
      const result = await this.authService.login(dto, ipAddress);
      await this.logService.log({
        userId: result.user.id, username: result.user.username,
        module: '认证', action: '登录成功',
        ipAddress, userAgent, status: 'success',
      });
      return result;
    } catch (e: any) {
      await this.logService.log({
        username: dto.username,
        module: '认证', action: '登录失败',
        detail: e.message || '密码错误',
        ipAddress, userAgent, status: 'fail',
      });
      throw e;
    }
  }

  @UseGuards(JwtAuthGuard)
  @Get('profile')
  getProfile(@Request() req: any) {
    return req.user;
  }
}

删除：

• POST /auth/register → 迁移至 /rbac/users POST

• GET /auth/users → 迁移至 /rbac/users GET

• PUT /auth/users/:id → 迁移至 /rbac/users/:id PUT

• PUT /auth/users/:id/password → 迁移至 /rbac/users/:id/password PUT

• DELETE /auth/users/:id → 迁移至 /rbac/users/:id DELETE

• Step 4: 修改 JwtStrategy

// backend/src/auth/strategies/jwt.strategy.ts
import { Injectable } from '@nestjs/common';
import { PassportStrategy } from '@nestjs/passport';
import { ExtractJwt, Strategy } from 'passport-jwt';
import { ConfigService } from '@nestjs/config';

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy) {
  constructor(config: ConfigService) {
    super({
      jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
      ignoreExpiration: false,
      secretOrKey: config.get('JWT_SECRET', 'dorm-billing-jwt-secret-key-2024'),
    });
  }

  async validate(payload: any) {
    return {
      id: payload.sub,
      username: payload.username,
      permissions: payload.permissions || [],
    };
  }
}

• Step 5: 编译验证

cd backend && npx tsc --noEmit

预期：无类型错误。如有循环依赖错误，确认 forwardRef 已正确配置。

• Step 6: Commit

git add backend/src/auth/
git commit -m "feat(rbac): integrate RbacService into AuthService login, update JWT payload"

Task 5: RbacController（角色 CRUD + 权限树 + 用户管理）

Files:

• Create: backend/src/rbac/rbac.controller.ts
• Create: backend/src/rbac/dto/rbac.dto.ts

Interfaces:

• Consumes: RbacService (Task 2), JwtAuthGuard (existing), @RequirePermission (Task 3)

• Produces: REST API endpoints for roles, permissions, and user management

• Step 1: 创建 DTO

// backend/src/rbac/dto/rbac.dto.ts
import { IsString, MinLength, IsOptional, IsArray, IsBoolean } from 'class-validator';

export class CreateRoleDto {
  @IsString()
  name: string;

• Step 3: 在 RbacService 中补充用户管理方法

在 backend/src/rbac/rbac.service.ts 中追加：

• Produces: PermissionGuard 作为 APP_GUARD 全局生效；RbacModule 初始化种子数据

• Step 1: 修改 AppModule

在 backend/src/app.module.ts 中：

1. 导入 PermissionGuard 和 RbacModule
2. entities 列表增加 Permission、Role
3. imports 增加 RbacModule
4. providers 增加 { provide: APP_GUARD, useClass: PermissionGuard }

import { Module } from '@nestjs/common';
import { APP_GUARD } from '@nestjs/core';
import { ConfigModule, ConfigService } from '@nestjs/config';
import { TypeOrmModule } from '@nestjs/typeorm';
import { ThrottlerModule, ThrottlerGuard } from '@nestjs/throttler';
import {
  Student, Room, Occupancy, RoomExpense, PersonalExpense,
  Bill, BillItem, User, OperationLog, Deposit, Classroom,
  Tenant, ClassroomRental, Permission, Role,
} from './entities';
import { AuthModule } from './auth/auth.module';
import { RbacModule } from './rbac/rbac.module';
import { StudentsModule } from './students/students.module';
import { RoomsModule } from './rooms/rooms.module';
import { OccupanciesModule } from './occupancies/occupancies.module';
import { ExpensesModule } from './expenses/expenses.module';
import { BillsModule } from './bills/bills.module';
import { DashboardModule } from './dashboard/dashboard.module';
import { OperationLogsModule } from './operation-logs/operation-logs.module';
import { DepositsModule } from './deposits/deposits.module';
import { ClassroomsModule } from './classrooms/classrooms.module';
import { TenantsModule } from './tenants/tenants.module';
import { ClassroomRentalsModule } from './classroom-rentals/classroom-rentals.module';
import { PermissionGuard } from './auth/guards/permission.guard';

@Module({
  imports: [
    ConfigModule.forRoot({ isGlobal: true }),
    ThrottlerModule.forRoot([{
      ttl: 60000,
      limit: 100,
    }]),
    TypeOrmModule.forRootAsync({
      imports: [ConfigModule],
      inject: [ConfigService],
      useFactory: (config: ConfigService): any => {
        const dbType = config.get('DB_TYPE', 'sqlite');
        const allEntities = [
          Student, Room, Occupancy, RoomExpense, PersonalExpense,
          Bill, BillItem, User, OperationLog, Deposit, Classroom,
          Tenant, ClassroomRental, Permission, Role,
        ];
        if (dbType === 'mysql') {
          return {
            type: 'mysql' as const,
            host: config.get('DB_HOST', 'localhost'),
            port: config.get<number>('DB_PORT', 3306),
            username: config.get('DB_USERNAME', 'root'),
            password: config.get('DB_PASSWORD', ''),
            database: config.get('DB_DATABASE', 'dorm_billing'),
            entities: allEntities,
            synchronize: true,
            charset: 'utf8mb4',
          };
        }
        return {
          type: 'better-sqlite3' as const,
          database: config.get('DB_DATABASE', 'dorm_billing.db'),
          entities: allEntities,
          synchronize: true,
        };
      },
    }),

    RbacModule,
    StudentsModule,
    RoomsModule,
    OccupanciesModule,
    ExpensesModule,
    BillsModule,
    DashboardModule,
    OperationLogsModule,
    DepositsModule,
    ClassroomsModule,
    TenantsModule,
    ClassroomRentalsModule,
  ],
  providers: [
    { provide: APP_GUARD, useClass: ThrottlerGuard },
    { provide: APP_GUARD, useClass: PermissionGuard },
  ],
})
export class AppModule {}

• Step 2: 启动验证

cd backend && npm run start:dev

预期：

• 种子数据初始化日志输出（42 个权限点、4 个角色）

• 无崩溃无错误

• 尝试不带 token 访问任意接口 → 返回 403

• Step 3: Commit

git add backend/src/app.module.ts
git commit -m "feat(rbac): register RbacModule and PermissionGuard in AppModule"

Task 7: 现有接口批量加 @RequirePermission

Files:

• Modify: backend/src/students/students.controller.ts
• Modify: backend/src/rooms/rooms.controller.ts
• Modify: backend/src/occupancies/occupancies.controller.ts
• Modify: backend/src/expenses/expenses.controller.ts
• Modify: backend/src/bills/bills.controller.ts
• Modify: backend/src/deposits/deposits.controller.ts
• Modify: backend/src/classrooms/classrooms.controller.ts
• Modify: backend/src/tenants/tenants.controller.ts
• Modify: backend/src/classroom-rentals/classroom-rentals.controller.ts
• Modify: backend/src/dashboard/dashboard.controller.ts
• Modify: backend/src/operation-logs/operation-logs.controller.ts

Interfaces:

• Consumes: @RequirePermission (Task 3)

• Produces: 所有业务接口受权限守卫保护

• Step 1: 为各 Controller 添加 @RequirePermission

对每个 Controller，在已有的 @UseGuards(JwtAuthGuard) 基础上，为每个路由方法添加 @RequirePermission 装饰器。权限码映射如下：

Controller	方法	权限码
StudentsController	findAll	student:view
StudentsController	findOne	student:view
StudentsController	create	student:create
StudentsController	update	student:edit
StudentsController	remove	student:delete
StudentsController	importExcel	student:import
StudentsController	exportExcel	student:export
RoomsController	findAll	room:view
RoomsController	findOne	room:view
RoomsController	create	room:create
RoomsController	update	room:edit
RoomsController	remove	room:delete
RoomsController	exportExcel	room:view
RoomsController	importExcel	room:create
OccupanciesController	findAll	occupancy:view
OccupanciesController	checkin	occupancy:checkin
OccupanciesController	checkout	occupancy:checkout
OccupanciesController	transfer	occupancy:transfer
ExpensesController	findAll	expense:view
ExpensesController	create	expense:create
ExpensesController	update	expense:edit
ExpensesController	remove	expense:delete
BillsController	findAll	bill:view
BillsController	generate	bill:generate
BillsController	confirm	bill:confirm
BillsController	remove	bill:delete
BillsController	exportExcel	bill:export-excel
BillsController	exportPdf	bill:export-pdf
DepositsController	findAll	deposit:view
DepositsController	create	deposit:create
DepositsController	update	deposit:edit
DepositsController	remove	deposit:delete
ClassroomsController	findAll	classroom:view
ClassroomsController	create	classroom:create
ClassroomsController	update	classroom:edit
ClassroomsController	remove	classroom:delete
TenantsController	findAll	tenant:view
TenantsController	create	tenant:create
TenantsController	update	tenant:edit
TenantsController	remove	tenant:delete
ClassroomRentalsController	findAll	rental:view
ClassroomRentalsController	create	rental:create
ClassroomRentalsController	update	rental:edit
ClassroomRentalsController	remove	rental:delete
DashboardController	全部	dashboard:view
OperationLogsController	全部	log:view

每个 Controller 的修改模式为：在文件头部 import RequirePermission，然后在每个方法上添加对应装饰器。例如 StudentsController：

// 在 imports 中添加
import { RequirePermission } from '../auth/decorators/permission.decorator';

// 每个方法前添加
@Get()
@RequirePermission('student:view')
findAll(...) { ... }

@Get(':id')
@RequirePermission('student:view')
findOne(...) { ... }

@Post()
@RequirePermission('student:create')
async create(...) { ... }

@Put(':id')
@RequirePermission('student:edit')
async update(...) { ... }

@Delete(':id')
@RequirePermission('student:delete')
async remove(...) { ... }

注意：

• Controller 上已有 @UseGuards(JwtAuthGuard) 不做修改

• rooms.controller.ts 的 getOverview、getVisual、downloadTemplate 等方法同样需要 room:view 权限

• bills.controller.ts 中 exportExcel 需要 bill:export-excel，exportPdf 需要 bill:export-pdf

• dashboard.controller.ts 和 operation-logs.controller.ts 的类级别加 @RequirePermission('dashboard:view') 和 @RequirePermission('log:view') 可以减少重复

• Step 2: 编译验证

cd backend && npx tsc --noEmit

预期：无类型错误。所有 Controller 的装饰器正确引用。

• Step 3: Commit

git add backend/src/students/ backend/src/rooms/ backend/src/occupancies/ backend/src/expenses/ backend/src/bills/ backend/src/deposits/ backend/src/classrooms/ backend/src/tenants/ backend/src/classroom-rentals/ backend/src/dashboard/ backend/src/operation-logs/
git commit -m "feat(rbac): add @RequirePermission decorators to all business controllers"

Task 8: 前端权限基础设施

Files:

• Create: frontend/src/hooks/usePermission.ts
• Create: frontend/src/components/PermissionButton.tsx
• Create: frontend/src/components/PermissionRoute.tsx
• Modify: frontend/src/pages/Login/index.tsx
• Modify: frontend/src/api/index.ts

Interfaces:

• Produces: usePermission() hook, PermissionButton 组件, PermissionRoute 组件

• Step 1: 创建 usePermission hook

// frontend/src/hooks/usePermission.ts
import { useMemo } from 'react';

export function usePermission() {
  const permissions: string[] = useMemo(() => {
    try {
      return JSON.parse(localStorage.getItem('permissions') || '[]');
    } catch {
      return [];
    }
  }, []);

  const hasPermission = (code: string): boolean => permissions.includes(code);

  const hasAnyPermission = (...codes: string[]): boolean =>
    codes.some(c => permissions.includes(c));

  const hasAllPermissions = (...codes: string[]): boolean =>
    codes.every(c => permissions.includes(c));

  return { permissions, hasPermission, hasAnyPermission, hasAllPermissions };
}

• Step 2: 创建 PermissionButton 组件

// frontend/src/components/PermissionButton.tsx
import React from 'react';
import { Button, ButtonProps } from 'antd';
import { usePermission } from '../hooks/usePermission';

interface PermissionButtonProps extends ButtonProps {
  permission: string;
  children: React.ReactNode;
}

const PermissionButton: React.FC<PermissionButtonProps> = ({ permission, children, ...btnProps }) => {
  const { hasPermission } = usePermission();
  if (!hasPermission(permission)) return null;
  return <Button {...btnProps}>{children}</Button>;
};

export default PermissionButton;

• Step 3: 创建 PermissionRoute 组件

// frontend/src/components/PermissionRoute.tsx
import React from 'react';
import { Result } from 'antd';
import { usePermission } from '../hooks/usePermission';

interface PermissionRouteProps {
  permission: string;
  children: React.ReactNode;
}

const PermissionRoute: React.FC<PermissionRouteProps> = ({ permission, children }) => {
  const { hasPermission } = usePermission();
  if (!hasPermission(permission)) {
    return (
      <Result
        status="403"
        title="无权访问"
        subTitle="您没有访问此页面的权限"
      />
    );
  }
  return <>{children}</>;
};

export default PermissionRoute;

• Step 4: 修改 Login 页面存储 permissions

在 frontend/src/pages/Login/index.tsx 的 onFinish 方法中，登录成功后存储 permissions：

// 在 try 块中，现有代码之后添加：
localStorage.setItem('permissions', JSON.stringify(res.user.permissions || []));

完整变更：

const onFinish = async (values: any) => {
  setLoading(true);
  try {
    const res: any = await api.post('/auth/login', values);
    localStorage.setItem('token', res.access_token);
    localStorage.setItem('user', JSON.stringify(res.user));
    localStorage.setItem('permissions', JSON.stringify(res.user.permissions || []));
    message.success('登录成功');
    navigate('/dashboard');
  } catch (err: any) {
    message.error(err?.message || '登录失败');
  } finally {
    setLoading(false);
  }
};

同时修改退出登录时的清理：

// 在 MainLayout.tsx 的 handleLogout 中（Task 10 会处理），
// 但此处先在 Login 页确保权限被正确存储

• Step 5: 修改 axios 拦截器处理 403

在 frontend/src/api/index.ts 中，在 401 处理逻辑之后增加 403 处理：

api.interceptors.response.use(
  (res) => res.data,
  (err) => {
    if (err.response?.status === 401) {
      localStorage.removeItem('token');
      localStorage.removeItem('user');
      localStorage.removeItem('permissions');
      window.location.href = '/login';
    }
    if (err.response?.status === 403) {
      // 403 不跳转登录，仅提示权限不足
      // 使用动态 import 避免循环依赖，或者简单 console 处理
      // 由于 antd message 在此处无法直接使用，延迟处理：
      const msg = err.response?.data?.message || '权限不足';
      console.warn('[403]', msg);
    }
    return Promise.reject(err.response?.data || err);
  },
);

注意：此处 403 提示需在各页面调用 api 时由 catch 块处理显示 message。具体在 Task 10 中各页面的 api 调用 catch 块中增加 403 判断。

• Step 6: 编译验证

cd frontend && npx tsc -b --noEmit

预期：无类型错误（可能需要处理 React 19 + Ant Design 6 的类型兼容问题，如有则忽略第三方类型错误）。

• Step 7: Commit

git add frontend/src/hooks/ frontend/src/components/PermissionButton.tsx frontend/src/components/PermissionRoute.tsx frontend/src/pages/Login/ frontend/src/api/
git commit -m "feat(frontend): add usePermission hook, PermissionButton, PermissionRoute, and 403 handling"

Task 9: 前端角色管理和权限一览页面

Files:

• Create: frontend/src/pages/Roles/index.tsx
• Create: frontend/src/pages/Permissions/index.tsx

Interfaces:

• Consumes: usePermission hook (Task 8), /rbac/roles API, /rbac/permissions API (Task 5)

• Produces: 角色管理页面（CRUD + 权限勾选），权限一览页面（只读分组展示）

• Step 1: 创建角色管理页面

// frontend/src/pages/Roles/index.tsx

Task 10: 前端路由、菜单和用户管理页面适配

Files:

• Modify: frontend/src/App.tsx
• Modify: frontend/src/layouts/MainLayout.tsx
• Modify: frontend/src/pages/Users/index.tsx
• Modify: 各业务页面中需要权限控制的按钮（约 11 个页面）

Interfaces:

• Consumes: usePermission, PermissionRoute, PermissionButton (Task 8), /rbac/users API (Task 5)

• Step 1: 修改 App.tsx 添加路由和权限包装

• Step 2: 修改 MainLayout 菜单过滤

// frontend/src/layouts/MainLayout.tsx
// 核心变更：
// 1. 导入 usePermission hook
// 2. 为每个菜单项添加 permission 字段
// 3. 使用 permissions 数组过滤（替代原来的 role === 'admin' 和 allowedMenus 逻辑）
// 4. 添加角色管理和权限一览菜单项
// 5. 退出登录时清除 permissions

• Step 3: 重构用户管理页面

在 frontend/src/pages/Users/index.tsx 中：

1. API 端点从 /auth/users 改为 /rbac/users，创建用户从 /auth/register 改为 /rbac/users POST
2. 角色列从单一 Tag（admin/operator）改为多角色 Tag 列表
3. 编辑弹窗角色从 Select 单选改为 Select mode="multiple"
4. 移除 allowedMenus 相关代码（MENU_OPTIONS 常量、Checkbox.Group）
5. 导入并加载可选角色列表（从 /rbac/roles）

export default UsersPage;

• Step 4: 各业务页面关键按钮添加 PermissionButton 包装

为以下页面的操作按钮添加 PermissionButton 包装：

页面	按钮	所需权限
Students	新增/导入	student:create / student:import
Students	编辑/删除/导出	student:edit / student:delete / student:export
Rooms	新增/导入	room:create
Rooms	编辑/删除/导出	room:edit / room:delete / room:view
Occupancies	办理入住/退宿/调换	occupancy:checkin / occupancy:checkout / occupancy:transfer
Expenses	新增	expense:create
Expenses	编辑/删除	expense:edit / expense:delete
Deposits	新增	deposit:create
Deposits	编辑/删除	deposit:edit / deposit:delete
Bills	生成/确认/导出	bill:generate / bill:confirm / bill:export-excel / bill:export-pdf
Bills	删除	bill:delete
Classrooms	新增/编辑/删除	classroom:create / classroom:edit / classroom:delete
Tenants	新增/编辑/删除	tenant:create / tenant:edit / tenant:delete
ClassroomRentals	新增/编辑/删除	rental:create / rental:edit / rental:delete

每个页面的修改模式：导入 PermissionButton，将 <Button> 替换为 <PermissionButton permission="...">。以 Students 页面为例：

import PermissionButton from '../../components/PermissionButton';

// 新增按钮
<PermissionButton permission="student:create" type="primary" icon={<PlusOutlined />} onClick={handleAdd}>
  新增学生
</PermissionButton>

// 导入按钮
<PermissionButton permission="student:import" icon={<UploadOutlined />} onClick={...}>
  导入
</PermissionButton>

// 删除按钮
<PermissionButton permission="student:delete">
  <Popconfirm title="确认删除？" onConfirm={() => handleDelete(record.id)}>
    <Button type="link" size="small" danger icon={<DeleteOutlined />}>删除</Button>
  </Popconfirm>
</PermissionButton>

• Step 5: 编译和启动验证

cd frontend && npx tsc -b --noEmit

预期：无新增类型错误（可忽略 Ant Design 6 与 React 19 的已知类型兼容警告）。

cd frontend && npm run dev

预期：前端正常启动，菜单按权限过滤，无权限页面显示 403。

• Step 6: Commit

Task 11: 验证与收尾

Files:

• Modify: backend/test/app.e2e-spec.ts (可选：更新 e2e 测试)

任务：端到端验证 RBAC 系统正确运行。

• Step 1: 启动后端验证种子数据

cd backend && npm run start:dev

验证日志输出：

已创建默认管理员: admin / admin123 (请尽快修改!)
种子数据初始化完成: 42 权限点, 4 角色

• Step 2: 验证登录流程

# 测试登录（admin/admin123）
curl -s -X POST http://localhost:3002/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"admin123"}' | python3 -m json.tool

预期响应包含：

• access_token 字符串

• user.permissions 数组包含 42 个权限码

• user.roles 数组包含 ["超管"]

• Step 3: 验证超管全通链路

用步骤 2 获取的 token：

TOKEN="<access_token>"

# 验证 GET /api/students 返回 200
curl -s -H "Authorization: Bearer $TOKEN" http://localhost:3002/api/students | python3 -m json.tool | head -5

# 验证 GET /api/rbac/roles 返回 200 且有数据
curl -s -H "Authorization: Bearer $TOKEN" http://localhost:3002/api/rbac/roles | python3 -m json.tool | head -10

预期：两个接口均返回 200 且包含数据。

• Step 4: 验证无权限拦截

# 不带 token 访问受保护接口
curl -s http://localhost:3002/api/students | python3 -m json.tool

预期：返回 403（或 NestJS 的 Forbidden 响应）。

# 带无效 token 访问
curl -s -H "Authorization: Bearer invalidtoken" http://localhost:3002/api/students

预期：返回 401。

• Step 5: 验证宿管老师受限链路

创建宿管老师角色用户，验证其只能访问学生模块而不能访问角色管理：

# 使用超管 token 创建测试用户
TOKEN="<admin_token>"
curl -s -X POST http://localhost:3002/api/rbac/users \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"username":"test_dorm","password":"123456","name":"测试宿管","roleIds":[2]}'

# 用测试用户登录
TEST_TOKEN=$(curl -s -X POST http://localhost:3002/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"username":"test_dorm","password":"123456"}' | python3 -c "import sys,json; print(json.load(sys.stdin)['access_token'])")

# 验证可访问学生管理
curl -s -H "Authorization: Bearer $TEST_TOKEN" http://localhost:3002/api/students | python3 -c "import sys; print('students OK' if len(sys.stdin.read()) > 10 else 'FAIL')"

# 验证角色管理被拒绝
curl -s -H "Authorization: Bearer $TEST_TOKEN" http://localhost:3002/api/rbac/roles | python3 -c "import sys; print('roles BLOCKED' if 'Forbidden' in sys.stdin.read() or '403' in sys.stdin.read() else 'FAIL')"

预期：students OK + roles BLOCKED。

• Step 6: 验证前端

cd frontend && npm run dev

• 打开浏览器访问 login 页面

• 用 admin/admin123 登录，确认：

  • 菜单显示全部项（包括角色管理、权限一览）
  • 数据面板、学生管理、角色管理均可正常访问
  • 操作按钮（新增、编辑、删除）均可见

• 用测试宿管用户登录，确认：

  • 学生管理可见，角色管理不可见
  • 学生页面的新增/导入按钮可见
  • 直接访问 /roles URL 显示 403 页面

• Step 7: 后端 lint 通过

cd backend && npm run lint

预期：无 lint 错误。如有格式问题，运行 npm run format 修复。

• Step 8: 提交验证结果

在验证全部通过后提交所有变更：

git add -A
git commit -m "chore(rbac): final verification and lint fixes"

自检

1. 设计文档覆盖

设计文档章节	对应任务
2. 数据模型	Task 1 (实体定义), Task 2 (种子数据)
3. 后端模块设计	Task 2 (RbacModule/Service), Task 4 (Auth 改造), Task 5 (Controller)
4. 权限守卫设计	Task 3 (装饰器 + PermissionGuard)
5. JWT 变更	Task 4 (JwtStrategy + AuthService.login)
6. 前端架构	Task 8 (hooks/components), Task 9 (Roles/Permissions pages), Task 10 (路由/菜单/Users 适配)
7. 迁移策略	Task 1 (实体变更), Task 6 (AppModule synchronize)
8. 种子数据初始化	Task 2 (RbacService.seedData)
9. 测试策略	Task 11 (验证步骤 1-8)
10. 风险与缓解	全局约束 (synchronize: true 本地开发)
11. 后续扩展预留	实体设计 (Permission.code 保持 module:action 格式)

2. 占位符扫描

• 无 TBD、TODO、implement later 字样
• 所有步骤均包含具体代码、命令和预期输出
• 所有文件路径均为项目实际路径

3. 类型一致性

• getUserPermissions(userId: number): Promise<string[]> — Task 2 定义，Task 4 AuthService.login() 调用，Task 3 PermissionGuard 从 req.user.permissions 消费
• findAllRoles() → 返回 Role[]（含 permissions: Permission[] 关联）— Task 2 定义，Task 5 Controller 调用，Task 9 前端 Roles 页面消费
• DTO 名称：CreateRoleDto, UpdateRoleDto, CreateUserDto, UpdateUserDto, ResetPasswordDto — Task 5 定义和使用
• @RequirePermission 装饰器签名：(...permissions: string[]) — Task 3 定义，Task 5/7 使用
• PermissionGuard 从 req.user.permissions 读取 — Task 4 JwtStrategy 设置，Task 3 消费
