How to pass Request object from route in Laravel? - laravel-5

Question

Following is my routes where I am calling my Controller directly in route.
How can I pass Request $request to my getBlog Function.. Or is there any way to directly get $request object in my getblog function of controller ???
$artObj = App::make('App\Http\Controllers\Front\ArticleController');
return $artObj->getBlog($id);
Code in Routes:
Route::get('/{slug}', function($slug) {
// Get Id and Type depending on url
$resultarray = App\Model\UrlAlias::getTypefromUrl($slug);
if(!empty($resultarray)) {
if($resultarray[0]['type'] == 'article') {
$id = $resultarray[0]['ref_id'] ;
$artObj = App::make('App\Http\Controllers\Front\ArticleController');
return $artObj->getBlog($id);
} else {
return Response::view("errors.404", $msg, 400);
}
} else {
return Response::view("errors.404", array(), 400);
}
});

You can do in the head of the routes.php file:
use Illuminate\Http\Request;
And then in the beginning of your route:
Route::get('/{slug}', function($slug, Request $request) {
And the $request will be available to you. But that is extremely bad practice. What you should do - is move the whole logic into the controller like that:
Route::group(['namespace' => 'Front'], function(){
Route::get('/{slug}', 'ArticleController#methodName');
});
and then you can use the Request class in your controller class and the controller method:
<?php
namespace App\Http\Controllers\Front
use Illuminate\Http\Request;
class ArticleController
{ ...
public function methodName(Request $request){
...function implementation...
}
...
}

The Request is a global variable, you can access it anywhere with either php code or even some helper Laravel functions.
Just use request() and it's the same as passing the request as an object inside a variable through a function. (It's equivalent to the Request $request variable received).
It improved readability also. Just remember you can't change request objects directly, you'd better use request()->merge(['key' => 'newValue']);
