This package can create URLs with a limited lifetime. This is done by adding an expiration date and a signature to the URL.
The difference with Laravel's native route signing is that using this package:
- you can easily use signed URLs between different apps
- the signing secret used is not tied to the app key
- you can easily sign any URL (and not only a route belonging to your app)
This is how you can create signed URL that's valid for 30 days:
use Spatie\UrlSigner\Laravel\Facades\UrlSigner;
UrlSigner::sign('https://myapp.com/protected-route', now()->addDays(30));The output will look like this:
https://app.com/protected-route?expires=xxxxxx&signature=xxxxxx
The URL can be validated with the validate-function.
// returns `true` if the signed URL is valid, `false` if not
UrlSigner::validate('https://app.com/protected-route?expires=xxxxxx&signature=xxxxxx');The package also provides a middleware to protect routes.

As you would have guessed the package can be installed via composer:
composer require spatie/laravel-url-signerYou must set an environment variable called URL_SIGNER_SIGNATURE_KEY and set it to a long secret value. This value will be used to sign and validate signed URLs.
# in your .env file
URL_SIGNER_SIGNATURE_KEY=some_random_value
The configuration file can optionally be published via:
php artisan vendor:publish --tag="url-signer-config"This is the content of the file:
return [
/*
* This string is used the to generate a signature. You should
* keep this value secret.
*/
'signature_key' => env('URL_SIGNER_SIGNATURE_KEY'),
/*
* The default expiration time of a URL in seconds.
*/
'default_expiration_time_in_seconds' => 60 * 60 * 24,
/*
* These strings are used a parameter names in a signed url.
*/
'parameters' => [
'expires' => 'expires',
'signature' => 'signature',
],
];URL's can be signed with the sign-method:
use Spatie\UrlSigner\Laravel\Facades\UrlSigner;
UrlSigner::sign('https://myapp.com/protected-route');By default, the lifetime of an URL is one day. This value can be change in the config file. If you want a custom lifetime, you can specify the number of days the URL should be valid:
use Spatie\UrlSigner\Laravel\Facades\UrlSigner;
// the generated URL will be valid for 5 minutes.
UrlSigner::sign('https://myapp.com/protected-route', now()->addMinutes(5));
// alternatively you could also pass the amount of seconds
UrlSigner::sign('https://myapp.com/protected-route', 60 * 5);To validate a signed URL, simply call the validate()-method. This method returns a boolean.
use Spatie\UrlSigner\Laravel\Facades\UrlSigner;
UrlSigner::validate('https://app.com/protected-route?expires=xxxxxx&signature=xxxxxx');The package provides a middleware to protect routes.
To use it you must first register the Spatie\UrlSigner\Laravel\Middleware\ValidateSignature as route middleware in your HTTP kernel.
// in app/Http/Kernel.php
protected $routeMiddleware = [
// ...
'signed-url' => \Spatie\UrlSigner\Laravel\Middleware\ValidateSignature::class,
];Next, you can apply it on any route you want.
Route::get('protected-route', fn () => 'Hello secret world!')
->middleware('signed-url');Your app will abort with a 403 status code if the route is called without a valid signature.
Please see CHANGELOG for more information what has changed recently.
You can run the test using this command:
composer testIf you're working on a non-Laravel project, you can use the framework agnostic version.
Please see CONTRIBUTING for details.
