Laravel - URL Generation - Signed Urls

Laravel allows you to easily create "signed" URLs to named routes. These URLs have a "signature" hash appended to the query string which allows Laravel to verify that the URL has not been modified since it was created. Signed URLs are especially useful for routes that are publicly accessible yet need a layer of protection against URL manipulation.

For example, you might use signed URLs to implement a public "unsubscribe" link that is emailed to your customers. To create a signed URL to a named route, use the signedRoute method of the URL facade:

    use Illuminate\Support\Facades\URL;
    return URL::signedRoute('unsubscribe', ['user' => 1]);

If you would like to generate a temporary signed route URL that expires after a specified amount of time, you may use the temporarySignedRoute method. When Laravel validates a temporary signed route URL, it will ensure that the expiration timestamp that is encoded into the signed URL has not elapsed:

    use Illuminate\Support\Facades\URL;
    return URL::temporarySignedRoute(
        'unsubscribe', now()->addMinutes(30), ['user' => 1]
