如何在Nest.js身份验证流程中传递状态

npm install passport passport-local

import { Module } from '@nestjs/common';
import { PassportModule } from '@nestjs/passport';
import { LocalStrategy } from './local.strategy';

@Module({
  imports: [
    PassportModule.register({ defaultStrategy: 'local' }),
  ],
  providers: [LocalStrategy],
})
export class AppModule {}

import { Injectable } from '@nestjs/common';
import { PassportStrategy } from '@nestjs/passport';
import { Strategy } from 'passport-local';

@Injectable()
export class LocalStrategy extends PassportStrategy(Strategy) {
  constructor() {
    super();
  }

  async validate(username: string, password: string): Promise<any> {
    // 在这里进行身份验证逻辑，验证成功返回用户对象，验证失败抛出异常
  }
}

import { Controller, Post, UseGuards } from '@nestjs/common';
import { AuthGuard } from '@nestjs/passport';

@Controller('auth')
export class AuthController {
  @Post('login')
  @UseGuards(AuthGuard('local'))
  async login() {
    // 身份验证成功后的处理逻辑
  }
}

import { Controller, Post, Req, UseGuards } from '@nestjs/common';
import { AuthGuard } from '@nestjs/passport';

@Controller('auth')
export class AuthController {
  @Post('login')
  @UseGuards(AuthGuard('local'))
  async login(@Req() req) {
    const user = req.user; // 获取验证成功的用户对象
    req.session.user = user; // 将用户对象存储在会话中
    // 其他处理逻辑
  }
}
