推荐答案

当您使用Route::get()方法为您的站点/应用程序添加路由时，以下功能是从Laravel'的Illuminate\Routing\Router.php类获取的，Laravel为url添加了这两种方法，这意味着使用get方法注册的这些url可以使用GET和HEAD HTTP方法以及

Following function is taken from the Laravel's Illuminate\Routing\Router.php class, when you use Route::get() method to add a route for your site/application, Laravel adds both methods for the url, it means that, these urls registered using getmethod could be accessed using both GET and HEAD HTTP method, and HEAD is just another HTTP verb/method, used for making a HEAD request.

/**
 * Register a new GET route with the router.
 *
 * @param  string  $uri
 * @param  \Closure|array|string  $action
 * @return \Illuminate\Routing\Route
 */
public function get($uri, $action)
{
    return $this->addRoute(array('GET', 'HEAD'), $uri, $action);
}
