How can I check if a URL exists via Laravel?
提问by rotaercz
I did look at this answer:
我确实看过这个答案：
How can I check if a URL exists via PHP?
However, I was wondering if a method exists in Laravel that can check if a URL exists (not 404) or not?
但是，我想知道 Laravel 中是否存在可以检查 URL 是否存在（不是 404）的方法？

I assume you want to check if a there's a route matching a certain URL.
我假设您想检查是否有与某个 URL 匹配的路由。
$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
}

Not particular laravel function, but you can make a try on this
不是特别的 Laravel 功能，但您可以尝试一下
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($ch);
return ($httpcode >= 200 && $httpcode < 300) ? true : false;
}

Since you mentioned you want to check an external URL (eg. https://google.com), not a route within the app , you can use use the Httpfacade in Laravel as such (https://laravel.com/docs/master/http-client):
由于您提到要检查外部 URL（例如https://google.com），而不是应用程序内的路由，因此您可以使用HttpLaravel 中的外观（https://laravel.com/docs/master/http-client）：
use Illuminate\Support\Facades\Http;
$response = Http::get('https://google.com');
if( $response->successful() ) {
// Do something ...
}

try this function
试试这个功能
function checkRoute($route) {
$routes = \Route::getRoutes()->getRoutes();
foreach($routes as $r){
if($r->getUri() == $route){
return true;
}
}
return false;
}
