FatalThrowableError:参数 1 已通过 ..::fromUser() laravel 5.6

问题描述

我使用邮递员添加用户或登录，用户添加成功但我收到此错误

I use postman to add user or to login , user has added with sucess but I get this error

"传递给 TymonJWTAuthJWT::fromUser() 的参数 1 必须是TymonJWTAuthContractsJWTSubject 的实例，AppUser 的实例给定，在 C:UsersWeb 中调用WorkStationDesktoplaravelappjwtlaravelvendor ymonjwt-authsrcJWTAuth.php第 54 行"

"Argument 1 passed to TymonJWTAuthJWT::fromUser() must be an instance of TymonJWTAuthContractsJWTSubject, instance of AppUser given, called in C:UsersWeb WorkStationDesktoplaravelappjwtlaravelvendor ymonjwt-authsrcJWTAuth.php on line 54"

我在这个 ligne 中找到了这个函数

and I found in this ligne this founction

 public function attempt(array $credentials)
    {
        if (! $this->auth->byCredentials($credentials)) {
            return false;
        }

        return $this->fromUser($this->user());
    }

这是我的用户模型:

    <?php

    namespace App;


    use TymonJWTAuthContractsJWTSubject;
    use IlluminateNotificationsNotifiable;
    use IlluminateFoundationAuthUser as Authenticatable;
    class User extends Authenticatable
    {
        use Notifiable;

        /**
         * The attributes that are mass assignable.
         *
         * @var array
         */
        protected $fillable = [
            'name', 'email', 'password','username','lastname','tel','tel',
        ];

        /**
         * The attributes that should be hidden for arrays.
         *
         * @var array
         */
        protected $hidden = [
            'password', 'remember_token',
        ];
        public function getJWTIdentifier()
        {
            return $this->getKey();
        }

        /**
         * Return a key value array, containing any custom claims to be added to the JWT.
         *
         * @return array
         */
        public function getJWTCustomClaims()
        {
            return [];
        }
    }
and this my register controller

<?php

namespace AppHttpControllers;
use AppHttpControllersController;
use IlluminateHttpRequest;
use AppUser;
use JWTFactory;
use JWTAuth;
use Validator;
use Response;

class APIRegisterController extends Controller
{
    //
    public function register( Request $request){
        $validator = Validator::make($request -> all(),[
         'email' => 'required|string|email|max:255|unique:users',
         'username' =>'required',
         'tel' => 'required',
         'name' => 'required',
         'lastname' => 'required',
         'adress' => 'required',
         'password'=> 'required'
        ]);

        if ($validator -> fails()) {
            # code...
            return response()->json($validator->errors());

        }

        User::create([
            'name' => $request->get('name'),
            'email' => $request->get('email'),
            'tel' => $request->get('tel'),
            'username' => $request->get('username'),
            'lastname' => $request->get('lastname'),
            'adress' => $request->get('adress'),
            'password'=> bcrypt($request->get('password'))
        ]);
        $user = User::first();
        $token = JWTAuth::fromUser($user);

        return Response::json( compact('token'));


    }
}

推荐答案

在你的 User 模型中实现 JWTSubject:

Implement the JWTSubject in your User model:

class User extends Authenticatable implements JWTSubject
