在nestjs应用程序中，为什么payload.sub在JwtStrategy的validate方法中未定义？

我正在开发一个

nestjs

应用程序，并使用

JwtStrategy

进行身份验证

我通过唱一些信息来生成

访问令牌

，包括

有效负载。sub

：

token.service.ts

async createAccessToken(
    payload: IJwtPayload,
    expires = this.expiresInDefault,
  ): Promise<LoginResponseVm> {

    ... other codes ....

    // sign
    // here payload is contain sub property and is filled by userId
    const signedPayload = sign(payload, this.jwtKey, options);
    const token: LoginResponse = {
      accessToken: signedPayload,
      expiresIn: expires,
    };

    return this.mapperService.map<LoginResponseVm>(
      token,
      LoginResponseVm.name,
      LoginResponse.name,
    );
  }

export interface IJwtPayload {
  sub: string;
  iat?: number;
  exp?: number;
  jti?: string;
}

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy) {
  constructor(
    private readonly tokenService: TokenService,
    configurationService: ConfigurationService,
  ) {
    super({
      jwtFromRequest: ExtractJwt.fromExtractors([
        ExtractJwt.fromAuthHeaderAsBearerToken(),
        ExtractJwt.fromUrlQueryParameter('access_token'),
      ]),
      secretOrKey: configurationService.JWT.Key,
      passReqToCallback: true,
    });
  }

  async validate(payload: IJwtPayload) {

    console.log(payload.sub); // <<--- Problem: payload.sub is undefined!
    const result = await this.tokenService.validatePayload(payload);
    if (!result) {
      throw new UnauthorizedException();
    }
    return result;
  }
}

但在运行项目时，使用生成的承载访问令牌填充请求的授权头，并在下面的验证方法上设置断点。有效负载有值，但

有效负载。sub

未定义为什么？

jwt战略.ts

async createAccessToken(
    payload: IJwtPayload,
    expires = this.expiresInDefault,
  ): Promise<LoginResponseVm> {

    ... other codes ....

    // sign
    // here payload is contain sub property and is filled by userId
    const signedPayload = sign(payload, this.jwtKey, options);
    const token: LoginResponse = {
      accessToken: signedPayload,
      expiresIn: expires,
    };

    return this.mapperService.map<LoginResponseVm>(
      token,
      LoginResponseVm.name,
      LoginResponse.name,
    );
  }

export interface IJwtPayload {
  sub: string;
  iat?: number;
  exp?: number;
  jti?: string;
}

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy) {
  constructor(
    private readonly tokenService: TokenService,
    configurationService: ConfigurationService,
  ) {
    super({
      jwtFromRequest: ExtractJwt.fromExtractors([
        ExtractJwt.fromAuthHeaderAsBearerToken(),
        ExtractJwt.fromUrlQueryParameter('access_token'),
      ]),
      secretOrKey: configurationService.JWT.Key,
      passReqToCallback: true,
    });
  }

  async validate(payload: IJwtPayload) {

    console.log(payload.sub); // <<--- Problem: payload.sub is undefined!
    const result = await this.tokenService.validatePayload(payload);
    if (!result) {
      throw new UnauthorizedException();
    }
    return result;
  }
}

@Injectable（）
导出类JwtStrategy扩展了PassportStrategy（策略）{
建造师(
专用只读令牌服务：令牌服务，
configurationService:configurationService，
) {
超级({
jwtFromRequest:ExtractJwt.fromExtractors([
从AuthHeaderAbarerToken（）中提取JWT，
ExtractJwt.fromUrlQueryParameter（“访问令牌”），
]),
secretrokey:configurationService.JWT.Key，
passReqToCallback：正确，
});
}
异步验证（有效负载：IJwtPayload）{
console.log（payload.sub）；//我替换了此签名：

async validate(payload: IJwtPayload) {

用这个

async validate(req: Request, payload: IJwtPayload, done: Function) {

    const result = await this.tokenService.validatePayload(payload);
    if (!result) {
       return done(new UnauthorizedException(), false);
    }
    done(null, result);
}

我找到了上面的签名
