How To Create URLs For Controller Actions In laravel

The action function generates a URL for the given controller action.

You do not need to pass the full namespace of the controller. Instead, pass the controller class name relative to the App\Http\Controllers namespace:
 

$url = action('HomeController@index');

use App\Http\Controllers\HomeController;

$url = action([HomeController::class, 'index']);

If the controller method accepts route parameters, you may pass them as the second argument to the function:

$url = action('UserController@profile', ['id' => 1]);

Default Values

For some applications, you may wish to specify request-wide default values for certain URL parameters. For example, imagine many of your routes define a {locale} parameter:
 

Route::get('/{locale}/posts', function () {
    //
})->name('post.index');

It is cumbersome to always pass the locale every time you call the route helper. So, you may use the URL::defaults method to define a default value for this parameter that will always be applied during the current request. You may wish to call this method from a route middleware so that you have access to the current request:
 

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\URL;

class SetDefaultLocaleForUrls
{
    public function handle($request, Closure $next)
    {
        URL::defaults(['locale' => $request->user()->locale]);

        return $next($request);
    }
}

Once the default value for the locale parameter has been set, you are no longer required to pass its value when generating URLs via the route helper.

Example(1)

1.Create route with action in routes\web.php file

Route::get(
    'demo/{name}',
    'demoController@demo'
);
$url = action(
    'demoController@demo',
    ['name' => 'Shiva']
);
echo '<br>'.$url;

2.Create demoController using below command

php artisan make:controller demoController

3.Open app\Http\demoController.php and implement below code in it

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;

class demoController extends Controller
{
    public function demo($name) {
        return "Hello, {$name}!";
    }
}

4.To see Output use below url
