【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

"传递给 Tymon\JWTAuth\JWT::fromUser() 的参数 1 必须是 Tymon\JWTAuth\Contracts\JWTSubject 的实例，App\User 的实例 给定，在 C:\Users\Web 中调用 WorkStation\Desktop\laravelapp\jwtlaravel\vendor\tymon\jwt-auth\src\JWTAuth.php 第 54 行"

我在这个 ligne 中找到了这个函数

 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 Tymon\JWTAuth\Contracts\JWTSubject;
    use Illuminate\Notifications\Notifiable;
    use Illuminate\Foundation\Auth\User 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 App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\User;
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'));


    

【参考方案1】：

这要求User Model 在你的模型中实现这个契约：

use Tymon\JWTAuth\Contracts\JWTSubject;

class User extends Model implements JWTSubject 

或者

你必须更新你的User model 来实现Tymon\JWTAuth\Contracts\JWTSubject 接口：

use Tymon\JWTAuth\Contracts\JWTSubject;

class User extends Model implements JWTSubject
    /**
     * Get the identifier that will be stored in the subject claim of the JWT.
     *
     * @return mixed
     */
    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 [];
    

【参考方案2】：

在您的用户模型中实现JWTSubject：

class User extends Authenticatable implements JWTSubject

【讨论】：

谢谢我的问题解决了，现在我得到 "token": null 但用户被添加到数据库中？我能做什么？

很高兴它有帮助。你跑php artisan jwt:secret了吗？
