如何在NestJS的Passport JWT验证函数中获取Express Request？

问题出在你没有开启Passport JWT的passReqToCallback配置项，默认情况下validate方法只会接收JWT payload作为第一个参数，导致你现在的参数顺序完全错位。

修复方法很简单：

• 在super()的配置对象中添加passReqToCallback: true，开启将Request对象传递给validate的功能
• 保持validate方法的参数顺序为(request: Request, payload: any)即可

修改后的完整代码：

import { Injectable } from '@nestjs/common';
import { ConfigService } from '@nestjs/config';
import { PassportStrategy } from '@nestjs/passport';
import { ExtractJwt, Strategy } from 'passport-jwt';
import { PrismaService } from 'src/prisma/prisma.service';
import { Request } from 'express';

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy, 'jwt') {
  constructor(config: ConfigService, private prisma: PrismaService) {
    super({
      jwtFromRequest: ExtractJwt.fromExtractors([
        (request: Request) => {
          //Check if user has cookie "access_token"
          if (
            request.cookies &&
            'access_token' in request.cookies &&
            request.cookies.access_token.length > 0
          ) {
            return request.cookies.access_token;
          }
          return null;
        },
      ]),
      ignoreExpiration: false,
      secretOrKey: config.get('JWT_SECRET'),
      // 添加这一行，开启传递Request到validate
      passReqToCallback: true,
    });
  }

  async validate(request: Request, payload: any) {
    console.log(request);
    console.log(payload);
    // 这里可以继续添加你的业务逻辑，比如根据payload查询用户等
  }
}
