Run Middleware Before Controller's Constructor On Laravel 5.1? - php

I have a middleware that authenticates a JWT user using tymon/jwt-auth package:
public function handle($request, \Closure $next)
{
if (! $token = $this->auth->setRequest($request)->getToken()) {
return $this->respond('tymon.jwt.absent', 'token_not_provided', 400);
}
try {
$user = $this->auth->authenticate($token);
} catch (TokenExpiredException $e) {
return $this->respond('tymon.jwt.expired', 'token_expired', $e->getStatusCode(), [$e]);
} catch (JWTException $e) {
return $this->respond('tymon.jwt.invalid', 'token_invalid', $e->getStatusCode(), [$e]);
}
if (! $user) {
return $this->respond('tymon.jwt.user_not_found', 'user_not_found', 404);
}
$this->events->fire('tymon.jwt.valid', $user);
return $next($request);
}
Then I have a controller and I want to pass the user from the middleware to the controller.
So I did on the controller:
public function __construct()
{
$this->user = \Auth::user();
}
The problem is that $this->user is null, but when I do this on a method of the controller, it's not null.
So:
public function __construct()
{
$this->user = \Auth::user();
}
public function index()
{
var_dump($this->user); // null
var_dump(\Auth::user()); // OK, not null
}
So the issue is that __construct is running before the middleware. How can I change that, or do you have another solution?
Update: I'm using dingo/api for routing, maybe it's an error on their side?

You should use the middleware(s) in the routes
Route::middleware('jwt.auth')->group(function() {
// your routes
});

1) Remove Your middleware from Your kernel's $middleware array
2) Put Your middleware to $routeMiddleware array with custom name jwt.auth:
protected $routeMiddleware = [
// ...
'jwt.auth' => 'App\Http\Middleware\YourAuthMiddleware'
];
2) Create BaseController in parent directory of needle controller, with function:
public function __construct() {
$this->middleware('jwt.auth');
}
3) Extend needle controller from BaseController
4) Make __construct function of needle controller to look like this:
public function __construct() {
parent::__construct();
$this->user = \Auth::user();
}

Why is the data lost in the parent constructor?

I have a class like this:
class BaseApiController extends Controller
{
protected $user;
function __construct()
{
$this->configHeaderRequest();
$this->validateToken();
}
protected function validateToken()
{
$this->middleware(function ($request, $next) {
if (Auth::guard('web')->user()) {
$this->user = Auth::guard('web')->user();
}
var_dump($this->user); //=> This is "user object" as well
return $next($request);
});
}
}
And another class that is extended from the class above:
class NewsController extends BaseApiController
{
public function __construct(Request $request)
{
parent::__construct($request);
$this->middleware(function ($request, $next) {
if (empty($this->user)) {
return $this->sendFailedResponse('Unauthorized Request', 401);
}
return $next($request);
});
}
public function search(Request $request): JsonResponse
{
var_dump($this->user); //=> but there is "null"
}
}
As you can see, $this->user will be null when I needed the user's object inside the search(Request $request) method while surprisingly the user's object exists inside the validateToken() method. Why? And how can I access the user's object there?

Call to a member function createData() on null using middleware on Laravel Transformers

So i created a controller for authentication with 2 methods (token() / native)_). Im using fractal transformer to return response. The token method works fine for me, but the loginAndroid() returns
"Call to a member function createData() on null" error.
Any help? Thank you.
class AuthController extends RestController
{
protected $transformer = UserTransformers::Class;
public function __construct()
{
$this->middleware('auth:api', ['except' => ['login', 'loginAndroid']]);
}
public function login(Request $request)
{
$credentials = $request->only(['username', 'password']);
if (!$token = auth()->attempt($credentials)) {
return response()->json(['error' => 'Unauthorized'], 401);
}
return $this->respondWithToken($token);
}
public function loginAndroid(Request $request)
{
$credentials = $request->only(['username', 'password']);
if (Auth::attempt($credentials)) {
//$user = Auth::user()->with(['employees']);
$userdata = User::with(['employees', 'employees.role', 'employees.branch'])->find(Auth::id());
//$success['token'] = $user->createToken('MyApp')->accessToken;
//return response()->json($userdata, 200);
//return $userdata;
$response = $this->generateItem($userdata);
return $this->sendResponse($response, 201);
} else {
return response()->json('gagal', 401);
}
}
}
this is my restcontroller
abstract class RestController extends Controller
{
protected $manager;
protected $transformer;
public function __construct()
{
$this->manager = new Manager();
}
protected function generateItem($model, $transformer = null)
{
if (!is_null($transformer)) {
return new Item($model, new $transformer);
}
return new Item($model, new $this->transformer);
}
protected function generateCollection($model, $transformer = null)
{
if (!is_null($transformer)) {
return new Collection($model, new $transformer);
}
return new Collection($model, new $this->transformer);
}
protected function sendResponse(ResourceInterface $data, $status = 200)
{
return response()->json(
$this->manager->createData($data)->toArray(),
$status
);
}
protected function sendNotFoundResponse($status)
{
return response()->json($status, 404);
}
protected function sendIseResponse($status)
{
return response()->json($status, 500);
}
}
It looks like your sendResponse() method depends on $this->manager. However, $this->manager gets set in RestController::__construct() and you've overridden the __construct() method in your AuthController::__construct(). So, in order to have $this->manager available, you should call the parent constructor from your AuthController, like this:
class AuthController extends RestController
{
protected $transformer = UserTransformers::Class;
public function __construct()
{
parent::__construct(); // call the parent constructor where
// $this->manager gets initialized
$this->middleware('auth:api', ['except' => ['login', 'loginAndroid']]);
}
... etc

Issue accessing Auth() object data in Laravel class

I am seeing some behaviour. I can't explain when accessing user data via the Auth facade in Laravel class. Here's an extract of my code:
private $data;
private $userID;//Set property
function __construct()
{
$this->middleware('auth');//Call middleware
$this->userID = Auth::id();//Define property as user ID
}
public function index() {
return view('');
}
public function MyTestMethod() {
echo $this->userID;//This returns null
echo Auth::id();//This works & returns the current user ID
}
I am logged in and have included use Illuminate\Support\Facades\Auth; in the class thus the code works, but only when accessing Auth in methods - else it returns a null value.
Most odd, I can't work out what is causing this. Any thoughts much appreciated as ever. Thanks in advance!
In Laravel Laravel 5.3.4 or above, you can't access the session or authenticated user in your controller's constructor, since the middlware isn't runnig yet.
As an alternative, you may define a Closure based middleware directly in your controller's constructor.:
try this :
function __construct()
{
$this->middleware(function ($request, $next) {
if (!auth()->check()) {
return redirect('/login');
}
$this->userID = auth()->id(); // or auth()->user()->id
return $next($request);
});
}
another alternative solution go you your base controller class and add __get function like this :
class Controller
{
public function __get(string $name)
{
if($name === 'user'){
return Auth::user();
}
return null;
}
}
and now if your current controller you can use it like this $this->user:
class YourController extends Controller
{
public function MyTestMethod() {
echo $this->user;
}
}
You should try this :
function __construct() {
$this->userID = Auth::user()?Auth::user()->id:null;
}
OR
public function __construct()
{
$this->middleware(function ($request, $next) {
$this->userID = Auth::user()->id;
return $next($request);
});
}

Laravel auth::guard('web')->user() is null in auth middleware

I put myRoute inside the auth middleware group and I get
// myController
Auth::guard('web')->user() // null
I dont know what to do.. I have controllers and routes below.
Seems like parent controller constructor is working but the middleware is not.
// Controller.php
public function __construct() {
$this->middleware(function ($request, $next) {
$this->currentUser = Auth::guard('web')->user();
return $next($request);
});
}
// myController extends Controller
public function __construct(Request $request) {
parent::__construct();
$this->request = $request;
var_dump($this->currentUser); // null
var_dump(Auth::guard('web')->user); // null
// $userId = Auth::guard('web')->user()->id;
// $userId = $this->currentUser->id;
$this->userId = $userId;
}
// route/web.php
Route::middleware(['auth'])->group(function () {
Route::get('myRoute', 'myController#index');
}
You can't get the Auth::user() in constructor. try Auth::guard('web')->user(); in another method. The result is not null anymore

Slim3 right way to set errors and check is user logged in

I'm a new user of Slim framework, I've a simple Slim 3 application, with sign in and sign up validation. But I'm not really sure if this is the right/best way to set errors and check if user is logged in -In order to redirect it to his account if session user.id exists.
I used a middleware: AuthMiddleware which includes:
class AuthMiddleware
{
protected $container;
public function __construct($container)
{
$this->container = $container;
}
public function __invoke($request, $response, $next)
{
if (isset($_SESSION['user.id']) && !empty($_SESSION['user.id'])) {
return $response->withRedirect($this->container->router->pathFor('user.index'));
}
$twig = $this->container->view->getEnvironment();
if (isset($_SESSION['validation'])) {
$twig->addGlobal('errors', $_SESSION['validation']['errors']);
$twig->addGlobal('values', $_SESSION['validation']['values']);
unset($_SESSION['validation']);
}
if (isset($_SESSION['auth.signup.success'])) {
$twig->addGlobal('auth_signup_success', $_SESSION['auth.signup.success']);
unset($_SESSION['auth.signup.success']);
}
if (isset($_SESSION['auth.signin.failed'])) {
$twig->addGlobal('auth_signin_failed', $_SESSION['auth.signin.failed']);
unset($_SESSION['auth.signin.failed']);
}
$response = $next($request, $response);
return $response;
}
}
And I used Twig for my views.
Session validation assigned in the validator.php which includes:
class Validator
{
protected $errors = [];
protected $values = [];
public function validate($request, $rules)
{
foreach ($rules as $field => $rule) {
$this->values[$field] = $request->getParam($field);
try {
$rule->setName(ucfirst($field))->assert($request->getParam($field));
} catch (NestedValidationException $e) {
$this->errors[$field] = $e->getMessages()[0];
}
}
if ($this->failed()) {
$_SESSION['validation'] = [
'errors' => $this->errors,
'values' => $this->values,
];
}
return $this;
}
public function failed()
{
return !empty($this->errors);
}
}
Using Respect\Validation. Also, is this the right use of Middlewares?
Thanks in advance.
try creating a separate file for the methods, and calling it from the middleware:
<?php
class AuthMiddleware extends Middleware {
public function __invoke($request, $response, $next) {
if (!$this->container->auth->check()) {
$this->container->flash->addMessage('danger', 'Please sign in to continue.');
return $response->withRedirect($this->container->router->pathFor('auth.signin'));
}
$response = $next($request, $response);
return $response;
}
}
while the Auth class would have those methods to check:
<?php
public function check () {
return isset($_SESSION['user']);
}
public function user() {
if (isset($_SESSION['user'])) {
return User::find($_SESSION['user'])->first();
} else {
return false;
}
}
Don't forget to include the Auth Class within your $app:
<?php
$container['auth'] = function ($container) {
return new \App\Auth\Auth();
};
