Middleware - Call to undefined method Illuminate\Auth\RequestGuard::handle() - lumen

Question

I am currently unable to protect my routes with the passport middleware. I am using lumen-passport, a package that makes Passport compatible with Lumen. When I attempt to hit the following route:
$app->get('/test', 'Game#test')->middleware('auth:api');
I get the following:
FatalThrowableError in AuthManager.php line 294:
Call to undefined method Illuminate\Auth\RequestGuard::handle()
in AuthManager.php line 294
at AuthManager->__call('handle', array(object(Request), object(Closure), 'api')) in Pipeline.php line 148
at Pipeline->Illuminate\Pipeline\{closure}(object(Request))
at call_user_func(object(Closure), object(Request)) in Pipeline.php line 32
at Pipeline->Laravel\Lumen\Routing\{closure}(object(Request)) in Pipeline.php line 102
at Pipeline->then(object(Closure)) in RoutesRequests.php line 780
at Application->sendThroughPipeline(array('auth:api'), object(Closure)) in RoutesRequests.php line 534
at Application->dispatch(null) in RoutesRequests.php line 475
at Application->run() in index.php line 28
My auth.php if it helps:
'defaults' => [
'guard' => 'api',
'passwords' => 'users',
],
'guards' => [
'api' => [
'driver' => 'passport',
'provider' => 'users',
],
],
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => \App\User::class
]
],
'passwords' => [
//
],
The route is correct as removing the middleware redirects to the appropriate controller as expected. Any help would be greatly appreciated.

Answer 1

For me the problem turned out to be my routes were in the wrong format. So to debug I commented out all existing routes and added the code (making sure APP_KEY=xxx is set in the .env file):
$app->group(['middleware' => 'auth:api'], function($app) {
$app->get('/user/info', function() {
$user = app('auth')->guard()->user();
return response()->json($user);
});
});
And the route /user/info worked without the error.
Then replaced my routes with the existing routes in the following format:
$app->group(['middleware' => 'auth:api'], function($app)
{
$app->get('/api/v1/users', [
'as' => 'listall', 'uses' => 'MyController#listModels'
]);
$app->get('/api/v1/users/{id}', [
'as' => 'list', 'uses' => 'MyController#listModel'
]);
$app->post('/api/v1/users', [
'as' => 'create', 'uses' => 'MyController#createModel'
]);
$app->delete('/api/v1/users/{id}', [
'as' => 'delete', 'uses' => 'MyController#deleteModel'
]);
$app->put('/api/v1/users/{id}', [
'as' => 'update', 'uses' => 'MyController#updateModel'
]);
});
And the error was no longer thrown.

In your bootstrap/app.php file, you need to make sure to uncomment the auth middleware setup.
https://github.com/laravel/lumen/blob/v5.4.0/bootstrap/app.php#L66-L68:
// $app->routeMiddleware([
// 'auth' => App\Http\Middleware\Authenticate::class,
// ]);
If the auth middleware is not registered, I believe Lumen will attempt to resolve auth out of the container (resolving to the AuthManager) and will attempt to treat it as middleware (calling handle on it, which doesn't exist).

I don´t know if you resolve your problem, but i had the same one and I resolved it adding the middleware 'auth:api' inside the constructor of the Controller, in my case UserController:
public function __construct(){
$this->middleware('auth:api');
}

Answer 4

you have to add this code in Authenticate.php
public function __construct(Guard $auth)
{
$this->auth = $auth;
}

Answer 5

All you have to do is in you app.php located in bootstrap folder.
There you should define passport middleware.
$app->routeMiddleware([
'auth' => App\Http\Middleware\Authenticate::class,
'client_credentials' => \Laravel\Passport\Http\Middleware\CheckClientCredentials::class
]);
When it's done you have to set your protected urls to client_credentials middleware.
When it's done try to make request with token to your protected route and for example return Auth::id().
You will receive user id for this token.
