This package will add CORS headers to the responses of your Laravel or Lumen app. Read [this excellent article](https://spring.io/understanding/CORS) on the subject if you want to understand what CORS is all about.
This package supports preflight requests and is easily configurable to fit your needs.
## Installation
- [Laravel](#laravel)
- [Lumen](#lumen)
### Laravel
You can install the package via Composer:
```bash
composer require spatie/laravel-cors
```
The package will automatically register its service provider.
The provided `Spatie\Cors\Cors` middleware must be registered in the global middleware group.
```php
// app/Http/Kernel.php
protected $middleware = [
...
\Spatie\Cors\Cors::class
];
```
```php
php artisan vendor:publish --provider="Spatie\Cors\CorsServiceProvider" --tag="config"
```
This is the default content of the config file published at `config/cors.php`:
```php
return [
/*
* A cors profile determines which orgins, methods, headers are allowed for
* a given requests. The `DefaultProfile` reads its configuration from this
* config file.
*
* You can easily create your own cors profile.
* More info: https://github.com/spatie/laravel-cors/#creating-your-own-cors-profile
*/
'cors_profile' => Spatie\Cors\CorsProfile\DefaultProfile::class,
/*
* This configuration is used by `DefaultProfile`.
*/
'default_profile' => [
'allow_credentials' => false,
'allow_origins' => [
'*',
],
'allow_methods' => [
'POST',
'GET',
'OPTIONS',
'PUT',
'PATCH',
'DELETE',
],
'allow_headers' => [
'Content-Type',
'X-Auth-Token',
'Origin',
'Authorization',
],
'expose_headers' => [
'Cache-Control',
'Content-Language',
'Content-Type',
'Expires',
'Last-Modified',
'Pragma',
],
'forbidden_response' => [
'message' => 'Forbidden (cors).',
'status' => 403,
],
/*
* Preflight request will respond with value for the max age header.
*/
'max_age' => 60 * 60 * 24,
],
];
```
### Lumen
You can install the package via Composer:
```bash
composer require spatie/laravel-cors
```
Copy the config file from the vendor directory:
```bash
cp vendor/spatie/laravel-cors/config/cors.php config/cors.php
```
Register the config file, the middleware and the service provider in `bootstrap/app.php`:
```php
$app->configure('cors');
$app->middleware([
Spatie\Cors\Cors::class,
]);
$app->register(Spatie\Cors\CorsServiceProvider::class);
```
## Usage
With the middleware installed your API routes should now get apprioriate CORS headers. Preflight requests will be handled as well. If a request comes in that is not allowed, Laravel will return a `403` response.
The default configuration of this package allows all requests from any origin (denoted as `'*'`). You probably want to at least specify some origins relevant to your project. If you want to allow requests to come in from `https://spatie.be` and `https://laravel.com` add those domains to the config file:
```php
// config/cors.php
...
'default_profile' => [
'allow_origins' => [
'https://spatie.be',
'https://laravel.com',
],
...
...
```
### Creating your own CORS profile
Imagine you want to specify allowed origins based on the user that is currently logged in. In that case the `DefaultProfile` which just reads the config file won't cut it. Fortunately it's very easy to write your own CORS profile, which is simply a class that extends `Spatie\Cors\DefaultProfile`.
Here's a quick example where it is assumed that you've already added an `allowed_domains` column on your user model:
```php
namespace App\Services\Cors;
use Spatie\Cors\CorsProfile\DefaultProfile;
class UserBasedCorsProfile extends DefaultProfile
{
public function allowOrigins(): array
{
return Auth::user()->allowed_domains;
}
}
```
You can override the default HTTP status code and message returned when a request is forbidden by editing the `forbidden_response` array in your configuration file:
```php
'forbidden_response' => [
'message' => 'Your request failed',
'status' => 400,
],
```
Don't forget to register your profile in the config file.
```php
// config/cors.php
...
'cors_profile' => App\Services\Cors\UserBasedCorsProfile::class,
...
```
In the example above we've overwritten the `allowOrigins` method, but of course you may choose to override any of the methods present in `DefaultProfile`.
