Laravel 6：调用未定义的方法 App\\User::createToken()

Question

我正在尝试通过以下方式生成一个令牌来验证我的 Controller 中的用户：

namespace App\Http\Controllers\API;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;

use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Auth;
use App\Models\User;

class AuthController extends Controller
{
    public function login()
    {
        if (Auth::attempt(['email' => request('email'), 'password' => request('password')])) {
            $user = Auth::user();


            $success['token'] = $user->createToken('myApp')->accessToken;
            dd($success['token']);

        }
    }

目前，我只是想打印出令牌。 这是我用户的 model：

<?php

namespace App\Models;

use Illuminate\Notifications\Notifiable;
//use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Support\Facades\Hash;
use Laravel\Passport\HasApiTokens;

class User extends Authenticatable
{
    use HasApiTokens, Notifiable;

    const USER_FIRST_NAME_FIELD        = "first_name";
    const USER_LAST_NAME_FIELD         = "last_name";
    const USER_PREFERRED_NAME_FIELD    = "preferred_name";
    const USER_EMAIL_FIELD             = "email";
    const USER_EMAIL_VERIFIED_AT_FIELD = "email_verified_at";
    const USER_PASSWORD_FIELD          = "password";
    const USER_REMEMBER_TOKEN_FIELD    = "remember_token";
    const USER_RECEIVE_NEWSLETTER_FIELD= "receive_newsletter";
    const USER_ACTIVE_FIELD            = "active";

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        self::USER_FIRST_NAME_FIELD, 
        self::USER_LAST_NAME_FIELD,
        self::USER_PREFERRED_NAME_FIELD,
        self::USER_EMAIL_FIELD,
        self::USER_PASSWORD_FIELD,
        self::USER_RECEIVE_NEWSLETTER_FIELD,
        self::USER_ACTIVE_FIELD,
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        self::USER_PASSWORD_FIELD,
        self::USER_REMEMBER_TOKEN_FIELD
    ];

    /**
     * Automatically creates password hash when password is submitted
     *
     * @param string $password
     * @return void
     */
    public function setPasswordAttribute(string $password) : void
    {
        $this->attributes['password'] = Hash::make($password);    
    }
}

如您所见，我正在使用HasApiTokens, Notifiable特征，但我的 controller 出现错误：

调用未定义的方法 App\User::createToken()

Passport 已正确安装和配置。

这里有一些奇怪的东西：

注册用户时（我使用单独的 controller 并且还使用服务）成功创建了一个令牌：

这是我的 controller：

<?php

namespace App\Http\Controllers\API;

use App\Services\UserService;
use Illuminate\Http\JsonResponse;
use App\Http\Controllers\Controller;
use App\Http\Requests\RegisterUserRequest;


class UserController extends Controller 
{
    private $user;

    public function __construct(UserService $user)
    {
        $this->user = $user;
    }

    public function store(RegisterUserRequest $request) : JsonResponse
    {
        // TODO: verify message on error

        $user = $this->user->register($request->validated());
        $token = $user->createToken('MyApp')->accessToken;
        dd($token);

        return response()->json(['status' => 201, 'user_id' => $user->id]);
    }

}

这是我的服务：

<?php

namespace App\Services;

use App\Models\User;
use App\Services\BaseServiceInterface;

class UserService implements BaseServiceInterface
{

    public function register(array $formValues) : User
    {
        // 'terms and conditions' should not be saved into the db, hence it's removed
        unset($formValues['terms_conditions']);
        return User::create($formValues);
    }

}

这是我的 model 再次：

<?php

namespace App\Models;

use Illuminate\Notifications\Notifiable;
//use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Support\Facades\Hash;
use Laravel\Passport\HasApiTokens;

class User extends Authenticatable
{
    use HasApiTokens, Notifiable;

    const USER_FIRST_NAME_FIELD        = "first_name";
    const USER_LAST_NAME_FIELD         = "last_name";
    const USER_PREFERRED_NAME_FIELD    = "preferred_name";
    const USER_EMAIL_FIELD             = "email";
    const USER_EMAIL_VERIFIED_AT_FIELD = "email_verified_at";
    const USER_PASSWORD_FIELD          = "password";
    const USER_REMEMBER_TOKEN_FIELD    = "remember_token";
    const USER_RECEIVE_NEWSLETTER_FIELD= "receive_newsletter";
    const USER_ACTIVE_FIELD            = "active";

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        self::USER_FIRST_NAME_FIELD, 
        self::USER_LAST_NAME_FIELD,
        self::USER_PREFERRED_NAME_FIELD,
        self::USER_EMAIL_FIELD,
        self::USER_PASSWORD_FIELD,
        self::USER_RECEIVE_NEWSLETTER_FIELD,
        self::USER_ACTIVE_FIELD,
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        self::USER_PASSWORD_FIELD,
        self::USER_REMEMBER_TOKEN_FIELD
    ];

正如我告诉你的，在创建用户时，令牌正在正确生成。

我会说Auth::user()没有直接调用我的 Model，但我不确定这是怎么回事。

知道为什么吗？ 谢谢

Answer 1

由于您的警卫返回了错误的User model, App\User ，您应该检查您的身份验证配置“config/auth.php”。 在providers数组中调整任何提供者，通常是users ，即使用App\User model 到App\Models\User 。

'providers' => [
    'users' => [
        'driver' => 'eloquent',
        // 'model' => App\User::class,
        'model' => App\Models\User::class,
    ],
    ...
],

Answer 2

就我而言，我错过了使用 Trait HasApiTokens这就是 laravel 无法创建令牌的原因。

只需打开 User.php

afetr 名称空间包括

use Laravel\Passport\HasApiTokens;

然后在 class 里面

use HasApiTokens

请注意：我使用的是 laravel 7。

Answer 3

您可以让auth.basic中间件为您进行身份验证，方法是在构造方法中调用它：

public function __construct()
    {
        $this->middleware('auth.basic'); 
    }

然后为当前经过身份验证的用户生成访问令牌，并将用户信息与访问令牌一起返回：

public function login()
    {
        $Accesstoken = Auth::user()->createToken('Access Token')->accessToken;

        return Response(['User' => Auth::user(), 'Access Token' => $Accesstoken]);
    }

现在 Controller 将如下所示：

    <?php


namespace App\Http\Controllers\API;

use App\Models\User;
use Illuminate\Support\Facades\Auth;
use App\Http\Controllers\API\BaseController;

class AuthController extends BaseController
{
        /**
         * Instantiate a new controller instance.
         *
         * @return void
         */
        public function __construct()
        {
            $this->middleware('auth.basic'); 
        }

        public function login()
        {
            $Accesstoken = Auth::user()->createToken('Access Token')->accessToken;

            return Response(['User' => Auth::user(), 'Access Token' => $Accesstoken]);
        }
    }

Answer 4

所以，这不是正确的方法，但它目前正在工作：

<?php

namespace App\Http\Controllers\API;

use App\Models\User;
use Illuminate\Support\Facades\Auth;
use App\Http\Controllers\API\BaseController;

class AuthController extends BaseController
{
    public function login()
    {
        if (Auth::attempt(['email' => request('email'), 'password' => request('password')])) {
            $authenticated_user = \Auth::user();
            $user = User::find($authenticated_user->id);
            dd($user->createToken('myApp')->accessToken);
        }

        dd('here');
    }
}

现在我看到了令牌。

我想以正确的方式做到这一点，所以如果有人可以帮助我，我仍然会很感激。 谢谢
