Download the PHP package spatie/laravel-url-signer without Composer

Create signed URLs with a limited lifetime in Laravel

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:

The output will look like this:

The URL can be validated with the validate-function.

The package also provides a middleware to protect routes.

Installation

As you would have guessed the package can be installed via composer:

You 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.

The configuration file can optionally be published via:

This is the content of the file:

Usage

URL's can be signed with the sign-method:

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:

Validating URLs

To validate a signed URL, simply call the validate()-method. This method returns a boolean.

Protecting routes with middleware

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.

Next, you can apply it on any route you want.

Your app will abort with a 403 status code if the route is called without a valid signature.
