Laravel检查路由中是否存在给定URL的路由

Question

By providing a URL I would like to know if there's any way to determine if the URL exists in my Laravel application (in comparison to "How can I check if a URL exists via Laravel?" which wants to check an external URL)?

I tried this but it always tells me the URL doesn't match:

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

Answer 1

In one of my Laravel application, I achieved it by doing the following

private function getRouteSlugs()
{
    $slugs  = [];
    $routes = Route::getRoutes();

    foreach ($routes as $route)
    {
        $parts = explode('/', $route->uri());
        foreach ($parts as $part)
        {
            $slug    = trim($part, '{}?');
            $slugs[] = $slug;
        }
    }

    return array_unique($slugs);
}

This function would help to get all the slugs that are registered within Laravel and then with a simple in_array you can check if that slug has been reserved.

EDIT

Based on your comment, you can extend the following function

private function getRouteSlugs()
{
    $slugs  = [];
    $routes = Route::getRoutes();

    foreach ($routes as $route)
    {
        $slugs[] = $route->uri();
    }

    return array_unique($slugs);
}

That will get you an array of items as such:

0 => "dashboard/news"
1 => "dashboard/post/news"
2 => "dashboard/post/news/{id}"
3 => "dashboard/post/news"

It should be easy enough from here to compare.
