新建权限守卫

nest g gu ./guard/authorization

import { Injectable, CanActivate, ExecutionContext } from '@nestjs/common'

@Injectable()
export class RolesGuard implements CanActivate {
  constructor(private readonly allowedRoles: string[]) {}

  canActivate(context: ExecutionContext): boolean {
    const request = context.switchToHttp().getRequest()
    const user = request.user
    console.log(this.allowedRoles)
    if (user && this.allowedRoles.includes(user.role)) {
      return true
    }
    return false
  }
}

模型

import { Entity, Column, PrimaryGeneratedColumn, BeforeInsert } from 'typeorm'
import * as bcrypt from 'bcrypt'
@Entity()
export class App {
  @PrimaryGeneratedColumn()
  id: number

  @Column()
  userName: string

  @Column()
  passWord: string

  @BeforeInsert()
  async hashPassword() {
    this.passWord = await bcrypt.hash(this.passWord, 10)
  }

  @Column({ default: true })
  isActive: boolean

  @Column({ default: 'user' })
  role: string
}

使用

import { Controller, Get, UseGuards } from '@nestjs/common'
import { AppService } from './app.service'
import { AuthGuard } from 'src/guard/authentication/authentication.guard'
import { RolesGuard } from 'src/guard/authorization/authorization.guard'
@Controller()
export class AppController {
  constructor(private readonly appService: AppService) {}

  @UseGuards(AuthGuard, new RolesGuard(['admin']))
  @Get()
  isAdmin() {
    return this.appService.isAdmin()
  }
}
