Nestjs如何将数据从AuthGuard传递到控制器

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

@Injectable()
export class AuthGuard implements CanActivate {
  canActivate(context: ExecutionContext): boolean | Promise<boolean> {
    const request = context.switchToHttp().getRequest();
    // 假设验证成功后，设置一些用户信息
    request.user = { id: 1, username: 'exampleUser' };
    return true;
  }
}

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

@Controller('profile')
@UseGuards(AuthGuard)
export class ProfileController {
  @Get()
  getProfile(@Request() req) {
    // 从req对象中获取用户信息
    return req.user;
  }
}

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

@Injectable()
export class AuthGuard implements CanActivate {
  canActivate(context: ExecutionContext): boolean | Promise<boolean> {
    const request = context.switchToHttp().getRequest();
    // 假设验证成功后，设置一些用户信息
    request.user = { id: 1, username: 'exampleUser' };
    return true;
  }
}

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

@Controller('profile')
@UseGuards(AuthGuard)
export class ProfileController {
  @Get()
  getProfile(@Req() req) {
    // 从req对象中获取用户信息
    return req.user;
  }
}

import { Injectable, CanActivate, ExecutionContext } from '@nestjs/common';
import { PassportStrategy } from '@nestjs/passport';
import { ExtractJwt, Strategy } from 'passport-jwt';

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

  async canActivate(context: ExecutionContext): Promise<boolean> {
    const user = this.validate(request.user);
    // 将用户信息设置到请求对象中
    request.user = user;
    return true;
  }

  validate(payload: any) {
    return { userId: payload.sub, username: payload.username };
  }
}

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

@Controller('profile')
@UseGuards(JwtAuthGuard)
export class ProfileController {
  @Get()
  getProfile(@Req() req) {
    // 从req对象中获取用户信息
    return req.user;
  }
}
