Laravel | 如果用户未经过身份验证，如何更改路由

Question

I don't know If this is possible with laravel or what is the best way to achieve it, i wan't if user click to like post or add to favorites and he is not authenticated to showing login form,

I want every visitor to have access to all posts, i have used before if(auth::check()) in my view to hide or display the buttons (like & favorite) if user authenticated, but i don't like this way. i want to display the buttons to all visitors but when a Unauthenticated user click on like button redirecting to login page. I tried to add this method to my routes but seems not working

if (Auth:check()){
  Route::post('/favorite/{post}', 'SiteController@favorite');
  Route::post('/unfavorite/{post}', 'SiteController@unFavorite');

  Route::post('/like/{post}', 'SiteController@like');
  Route::post('/update/{post}', 'SiteController@update');
  Route::post('/unlike/{post}', 'SiteController@unLike');

} else {

  Route::get('/login', ['as' => 'login', 'uses' => 'Auth\LoginController@showLoginForm']);

You are supposed to use middlewares for things like this. Group the routes you want only logged in users to have access to and use a middleware on that route to check if the user is authenticated.

Example: web.php

<?php
// Routes for logged in users.
$router->group(['middleware' => ['auth']], function($router) {
    $router->get('foobar', ['as' => 'foobar', 'uses' => 'FooController@index']);
});

// Routes for all users.
$router->get('bar', ['as' => 'bar', 'uses' => 'BarController@index']);

App\Http\Middleware\Authenticate.php

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\Auth;

class Authenticate
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @param  string|null  $guard
     * @return mixed
     */
    public function handle($request, Closure $next, $guard = null)
    {
        if (Auth::guard($guard)->guest()) {
            if ($request->ajax() || $request->wantsJson()) {
                return response('Unauthorized.', 401);
            } else {
                return redirect()->guest(route('bar'));
            }
        }

        view()->share('user', Auth::user());

        return $next($request);
    }
}

Then in App\Http\Kernel.php you add this to your $routeMiddleware array:

'auth' => \App\Http\Middleware\Authenticate::class,
