Question

我是Laravel的新手，并且在laravel 5.5.18中使用JWT auth，但对我不起作用，它在api登录中给出了错误 Interface 'Tymon\JWTAuth\Contracts\JWTSubject' not found"

任何人都可以帮助我如何解决它。

谢谢

Answer 1

删除以前安装的jwt

composer remove tymon/jwt-auth
composer dump-autoload

然后安装

composer require tymon/jwt-auth:dev-develop --prefer-source

php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\LaravelServiceProvider"

php artisan jwt:secret

Route::post('login', 'ApiController@login');
Route::post('register', 'ApiController@register');

Route::group(['middleware' => 'auth.jwt'], function () {
    Route::get('logout', 'ApiController@logout');
    Route::get('user', 'ApiController@getAuthUser');

});

?php

namespace App;

use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Tymon\JWTAuth\Contracts\JWTSubject;

class User extends Authenticatable implements JWTSubject
{
    use Notifiable;

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

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    /**
     * 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 [];
    }
}

<?php
namespace App\Http\Controllers;
use App\User;
use Illuminate\Http\Request;
use JWTAuth;
use Tymon\JWTAuth\Exceptions\JWTException;

class ApiController extends Controller
{
    public function register(Request $request)
    {
        $user = new User;
        $user->name = $request->name;
        $user->email = $request->email;
        $user->password = bcrypt($request->password);
        $user->save();

        return response()->json([
            'success' => true,
            'data' => $user
        ], 200);
    }

    public function login(Request $request)
    {
        $input = $request->only('email', 'password');
        $jwt_token = null;

        if (!$jwt_token = JWTAuth::attempt($input)) {
            return response()->json([
                'success' => false,
                'message' => 'Invalid Email or Password',
            ], 401);
        }

        return response()->json([
            'success' => true,
            'token' => $jwt_token,
        ]);
    }

    public function logout(Request $request)
    {
        $this->validate($request, [
            'token' => 'required'
        ]);

        try {
            JWTAuth::invalidate($request->token);

            return response()->json([
                'success' => true,
                'message' => 'User logged out successfully'
            ]);
        } catch (JWTException $exception) {
            return response()->json([
                'success' => false,
                'message' => 'Sorry, the user cannot be logged out'
            ], 500);
        }
    }

    public function getAuthUser(Request $request)
    {
        $this->validate($request, [
            'token' => 'required'
        ]);

        $user = JWTAuth::authenticate($request->token);

        return response()->json(['user' => $user]);
    }
}

您可以考虑使用 Laravel Passport

来自laravel官方文档： https://laravel.com/docs/5.8/passport

Laravel使用Laravel Passport使API身份验证变得轻而易举，它可以在几分钟内为您的Laravel应用程序提供完整的OAuth2服务器实现。 Passport建立在由Andy Millington和Simon Hamp维护的League OAuth2服务器之上。

实际上，由于该库是由Laravel的创建者维护的，因此与其他并发库相比，它对于Laravel而言将是最新且稳定的。

laravel 5.5不支持jwt auth lib
