Jwt-auth: Class 'App\Http\Controllers\Api\JWTAuth' not found

[NickvdMeij]

Hi,

After installing the 0.5.0 version of jwt-auth in my Laravel 5 project.
I get the error

FatalErrorException in AuthController.php line 18:
Class 'App\Http\Controllers\Api\JWTAuth' not found

when I access my route.

Here is my code in the controller:

<?php namespace App\Http\Controllers\Api;

use App\Http\Requests;
use App\Http\Controllers\Api\ApiController;

use Tymon\JWTAuth\Exceptions\JWTException;

use Illuminate\Http\Request;

class AuthController extends ApiController {

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

        try {
            // attempt to verify the credentials and create a token for the user
            if (! $token = JWTAuth::attempt($credentials)) {
                return response()->json(['error' => 'invalid_credentials'], 401);
            }
        } catch (JWTException $e) {
            return response()->json(['error' => 'could_not_create_token'], 500);
        }

        return response()->json(compact('token'));
    }
}

I did follow the wiki, and added the provider and alias

Looks like you need to import the class because you are within a namespace.

Either by prefixing JWTAuth (\JWTAuth) with a backslash where you using it or adding the use statement at the top of your class:

use Tymon\JWTAuth\Facades\JWTAuth;
// or
use JWTAuth;

or you could always inject the instance via the constructor:

<?php namespace App\Http\Controllers\Api;

use App\Http\Controllers\Api\ApiController;
use Tymon\JWTAuth\Exceptions\JWTException;
use Tymon\JWTAuth\JWTAuth;
use Illuminate\Http\Request;

class AuthController extends ApiController {

    protected $auth;

    public function __construct(JWTAuth $auth)
    {
        $this->auth = $auth;
    }

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

        try {
            // attempt to verify the credentials and create a token for the user
            if (! $token = $this->auth->attempt($credentials)) {
                return response()->json(['error' => 'invalid_credentials'], 401);
            }
        } catch (JWTException $e) {
            return response()->json(['error' => 'could_not_create_token'], 500);
        }

        return response()->json(compact('token'));
    }
}

That worked, nice!
I'd suggest adding this to the documentation, so other wont encounter the same problem ;-)

Hi,

Please follow the instruction at https://github.com/tymondesigns/jwt-auth/wiki/Installation

it worked for me after changing config/app.php aliases from

'JWTAuth' => Tymon\JWTAuthFacades\JWTAuth::class,
to
'JWTAuth' => 'Tymon\JWTAuth\Facades\JWTAuth',

Change controller line
use JWTAuth;
with
use Tymon\JWTAuth\Facades\JWTAuth;

@vikramparihar Hi, can you help me understand why use JWTAuth throws an error when I try to use toUser() even though I configured it in the config/app.php aliases.

Also, why does use Tymon\JWTAuth\Facades\JWTAuth work, what's the difference?

This fix does not work for Lumen 5.5 ... I receive the following error

BindingResolutionException
Unresolvable dependency resolving [Parameter #0 [ $app ]] in class Illuminate\Cache\CacheManager

Please advice ...
