JWT 根据数据生成 token 时, 报错: JWT payload does not contain the required claims?

 //这个 $user 是从 MongoDB 中取出的数据
        $user = [
            'id' => 1,
            'username' => "123",
            'moblie' => 0,
            'qq' => 0,
            'weixin' => 0,
            'data_table' => 'app_user_data_1'
        ];
        $payload = JWTFactory::make($user);
        //报错: JWT payload does not contain the required claims?
        $token = JWTAuth::encode($payload);

        //直接从数据库取出取出, 但是User:first()取出的是object,
        //能返回token
        $user = User::first();
        $token= JWTAuth::fromUser($user);
//        dd($token);
        $data =['token' => $token];
        return $this->response->array($data);

怎么根据数组生成token尼???
