如何从 jwt 策略中获取 payload？

Question

我有jwt攻略：

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
    }
}

那么如何获取jwt策略返回的controller中的payload呢？

Answer 1

JwtStrategy#validate 的值 returned/resolved 将是 req.user

的值

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