【问题描述】：

我有 jwt 策略：

export class JwtStrategy extends PassportStrategy(Strategy, "jwt") 
    constructor() 
        super(
            ignoreExpiration: false,
            secretOrKey: "secret",
            jwtFromRequest: ExtractJwt.fromExtractors([
                (request: Request) => 
                let data = request.cookies['access'];
                    return data;
                
            ]),
        );
    

    async validate(payload: any)
        return payload;
    

这是我的控制器：

export class AuthController 
    constructor(private authService: AuthService) 

    @UseGuards(AuthGuard("jwt"))
    @Get()
    getPayload() 
        //here I need to get the payload that was returned in jwt strategy
    

那么我怎样才能在控制器中获取 jwt 策略中返回的有效负载呢？

【参考方案1】：

JwtStrategy#validate 返回/解析的值将是req.user 的值

import  Req  from '@nestjs/common'
// ...
    @UseGuards(AuthGuard("jwt"))
    @Get()
    getPayload(@Req() req: any) 
       console.log(req.user)
