How to modify the return of request()->getHttpHost() in Laravel 5.
I used a middelware to modify $_SERVER[HTTP_HOST], but it was not affected.
class ModifyHttpHost
{
public function handle($request, Closure $next)
{
$_SERVER['HTTP_HOST'] = 'another.com';
return $next($request);
}
}

i added header in middleware and i want to check in my controller that header that i set exists or not . the problem i cant watch headers in controller debugging? how can i do that? anyway use case for this is cors problem
this is my middleware:
public function handle(Request $request, Closure $next)
{
return $next($request)
->header('Access-Control-Allow-Origin', '*');
}
and this is my controller:
public function action()
{
dd(request()->headers->get("Access-Control-Allow-Origin")); //always null
}
You need to call the set method:
public function handle(Request $request, Closure $next)
{
$request->headers->set('Access-Control-Allow-Origin', '*');
return $next($request);
}
Then you can retrieve the header:
public function action()
{
dd(request()->headers->get("Access-Control-Allow-Origin")); // *
}
I am trying to send a variable to terminate of middleware from route:
Route::group(['middleware' => 'checkUserLevel'], function () {
// my routes
});
I can get checkUserLevel in handle of middleware but I need to access in terminate method too, what should I do?
public function handle($request, Closure $next, $key)
{
dd($key); // it returns variable
}
public function terminate($request, $response)
{
//I need that variable here
}
As mentioned in documentation, if you would like to use the same instance of middleware (because by default it is using the fresh instance of middleware) you need to register the middleware as singleton.
You can register it as singleton by adding to your ServiceProvider's register method
public function register()
{
$this->app->singleton(\App\Http\Middleware\YourMiddleware::class);
}
Then you can use the class' property like the first example of lorent's answer
protected $foo;
public function handle($request, Closure $next)
{
$this->foo = 'bar';
return $next($request);
}
public function terminate($request, $response)
{
// because we cannot use `dd` here, so the example is using `logger`
logger($this->foo);
}
You can do:
protected $key;
public function handle($request, Closure $next, $key)
{
$this->key = $key;
}
public function terminate($request, $response)
{
$this->key; //access property key
}
even though this should be passed via request global. Like:
public function handle($request, Closure $next)
{
$request->input('key');
}
public function terminate($request, $response)
{
$request->input('key');
}
Edited:
Route::group(['middleware' => 'checkUserLevel'], function () {
Route::get('/test/{testparam}', function () {
});
});
public function handle($request, Closure $next)
{
$request->route('testparam');
}
public function terminate($request, $response)
{
$request->route('testparam');
}
I know this is ages old, but you could also use a static property. That saves you from having to register a singleton:
<?php
namespace App\Http\Middleware;
class MyMiddleware {
private static $key;
public function handle($request, Closure $next, $key)
{
self::$key = ($key); // it returns variable
}
public function terminate($request, $response)
{
$key = self::$key;
}
}
This works in my Laravel 5.8 application, don't see why it wouldnt' work anywhere else. Cannot say if there's any reason NOT to do this, but I don't know of one.
I'm using this myself to generate a Cache key in my handle function, and reuse the same key in my terminate function.
I am trying to process 2 middleware before routing it to controller. Laravel won't give me an error on the following code but it only processes the 1st middleware 'CheckReferer' and won't process the 2nd middleware 'CheckCart'. It process the 1st middleware even if you change the sequence (e.g 'CheckCart', 'CheckReferer').
web.php
Route::prefix($language)->middleware('CheckReferer', 'CheckCart')->group(function() {
Route::get('/', 'HomeController#getIndex')->name('home');
});
CheckReferer.php (Middleware)
class CheckReferer
{
public function handle($request, Closure $next)
{
$Referer = isset($_SERVER['HTTP_REFERER']) ? $_SERVER['HTTP_REFERER'] : null;
if($Referer != null) {
$url_parsed = parse_url($Referer);
if ($url_parsed['host'] == 'www.example.com') {
$Referer = true;
Session::put('Referer', $Referer);
}
}
return $next($request);
}
}
CheckCart.php (Middleware)
class CheckCart
{
public function handle(Request $request, Closure $next)
{
$oldCart = Session::has('Cart') ? Session::get('Cart') : null;
return $next($request);
}
}
Pass them as array...
Route::prefix($language)->middleware(['CheckReferer', 'CheckCart'])->group(function() {
Route::get('/', 'HomeController#getIndex')->name('home');
});
this my middleware:
<?php
namespace App\Http\Middleware;
use Closure;
class CheckSession
{
public function handle($request, Closure $next)
{
return $next($request);
}
public function CheckSessionPageReuestTokenFailed($request, $next)
{
if ($request->session()->has('request_failed')) {
return $next($request);
} else {
echo 'forbidden';
}
}
}
how i can use method CheckSessionPageReuestTokenFailed($request, $next)?
thanks
Why you have written this method ?. you can write this code into handle method.
public function handle($request, Closure $next)
{
if ($request->session()->has('request_failed')) {
return $next($request);
} else {
echo 'forbidden';
}
}
and also you need register this middleware into $routeMiddleware array in
app/Http/Kernel.php file.
add this line:
'CheckSession' => CheckSession::class,
read laravel documentation to know more https://laravel.com/docs/5.4/middleware
public function handle($request, Closure $next)
{
$this->CheckSessionPageReuestTokenFailed($request, $next);
return $next($request);
}
You can use inside handle() method.
public function handle($request, Closure $next)
{
$this->CheckSessionPageReuestTokenFailed($request, $next);
return $next($request);
}
I have 2 Middlewares.
My StaffMiddleware
public function handle($request, Closure $next)
{
if( $request->user()->role->name != 'staff'){
return redirect()->route('store');
}
return $next($request);
}
My AdminMiddleware
public function handle($request, Closure $next)
{
if( $request->user()->role->name != 'admin'){
return redirect()->route('store');
}
return $next($request);
}
The Problem is my UnitController
public function __construct(UnitInterface $unit){
$this->middleware('staff');
$this->middleware('admin);
$this->unit = $unit;
}
It should work either the role is a staff or an admin. Do I need to create another Middleware to combine them both?
This completely depends on the way your Middleware is designed. As you can see from your code, it simple redirects if the role is not staff or not admin so there would be no way for you to have an OR logic.
However, you could use middleware parameters to avoid this.
$this->middleware('role:admin,staff');
This will use the role middleware and pass admin and staff as parameters.
Then you can use these parameters in your middleware:
public function handle($request, Closure $next, ...$params)
{
if(!in_array($request->user()->role->name, $params)){
return redirect()->route('store');
}
return $next($request);
}
This captures the additional parameters into an array $params in which you can check if the user's role matches one of the parameters.
**try this**
public function __construct(UnitInterface $unit){
$this->middleware(function ($request, $next) {
if($request->user()->role->name == 'staff' || $request->user()->role->name == 'admin')
{
return $next($request);
}
return redirect()->route('store')
});
}
No middleware
