如何在Nestjs中获取登录用户的属性

npm install @nestjs/passport passport passport-jwt jsonwebtoken

import { Injectable, ExecutionContext } from '@nestjs/common';
import { AuthGuard as NestAuthGuard } from '@nestjs/passport';

@Injectable()
export class AuthGuard extends NestAuthGuard('jwt') {
  canActivate(context: ExecutionContext) {
    return super.canActivate(context);
  }
}

import { Module } from '@nestjs/common';
import { PassportModule } from '@nestjs/passport';
import { JwtModule } from '@nestjs/jwt';
import { AuthService } from './auth.service';
import { JwtStrategy } from './jwt.strategy';
import { UserController } from './user.controller';

@Module({
  imports: [
    PassportModule.register({ defaultStrategy: 'jwt' }),
    JwtModule.register({
      secret: 'your-secret-key',
      signOptions: { expiresIn: '1h' },
    }),
  ],
  controllers: [UserController],
  providers: [AuthService, JwtStrategy],
})
export class AppModule {}

import { Injectable } from '@nestjs/common';
import { PassportStrategy } from '@nestjs/passport';
import { Strategy, ExtractJwt } from 'passport-jwt';
import { AuthService } from './auth.service';

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy) {
  constructor(private readonly authService: AuthService) {
    super({
      jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
      ignoreExpiration: false,
      secretOrKey: 'your-secret-key',
    });
  }

  async validate(payload: any) {
    return this.authService.validateUser(payload); // 根据实际情况修改此处的验证逻辑
  }
}

import { Controller, Get, UseGuards, Req } from '@nestjs/common';
import { AuthGuard } from './auth.guard';

@Controller('users')
export class UserController {
  @Get('profile')
  @UseGuards(AuthGuard)
  getProfile(@Req() request) {
    return request.user;
  }
}
