如何通過Laravel檢查URL是否存在？

Question

我沒看這個答案：

How can I check if a URL exists via PHP?

不過，我在想，如果一種方法在Laravel存在，可以檢查是否存在URL（不是404）或不？

Answer 1

我假設你想檢查是否有一個匹配某個URL的路由。

$routes = Route::getRoutes(); 
$request = Request::create('the/url/you/want/to/check'); 
try { 
    $routes->match($request); 
    // route exists 
} 
catch (\Symfony\Component\HttpKernel\Exception\NotFoundHttpException $e){ 
    // route doesn't exist 
} 

Answer 2

試試這個功能

function checkRoute($route) { 
    $routes = \Route::getRoutes()->getRoutes(); 
    foreach($routes as $r){ 
     if($r->getUri() == $route){ 
      return true; 
     } 
    } 

    return false; 
}

不是特別laravel功能，但你可以在這個

function urlExists($url = NULL) 
{ 
    if ($url == NULL) return false; 
    $ch = curl_init($url); 
    curl_setopt($ch, CURLOPT_TIMEOUT, 5); 
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
    $data = curl_exec($ch); 
    $httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE); 
    curl_close($ch); 
    if ($httpcode >= 200 && $httpcode < 300) { 
     return true; 
    } else { 
     return false; 
}
