Laravel API blocked by CORS Policy | Resolved

If you have been running into an error message that tells you that Laravel API is blocked by CORS policy, it means that the web browser is blocking requests to our API from a different origin due to security restrictions.

CORS is a security feature in web browsers that prevents potential CSRF and other security vulnerabilities.

Today, we are going to take a look at how to fix this error in our Laravel API:

1. To begin with, we have to install a package to handle CORS headers. A popular package is fruitcake/laravel-cors. We can install it with Composer.
2. Then, we have to register the Cors middleware in our app/Http/Kernel.php file.
   This is done by adding it to the $middleware array:

   
protected $middleware = [
// ...
\Fruitcake\Cors\HandleCors::class,
];
3. Now, it is time to publish the configuration file for the laravel-cors package with the Artisan command:

   php artisan vendor:publish –tag=cors

   This command will create a config/cors.php configuration file.
4. Then, open the config/cors.php file and configure it as per our needs. We can mention which origins, methods, headers, and other settings are allowed for our API.

   For example:

   'paths' => ['api/*'],
'allowed_methods' => ['*'],
'allowed_origins' => ['*'],
'allowed_headers' => ['*'],
'exposed_headers' => [],
'max_age' => 0,
'supports_credentials' => false,


   We can adjust these settings to match our needs.
5. At this point, we have to test our API requests from different origins to make sure that the CORS policy is correctly configured and that we can make requests without encountering CORS errors.
6. Finally, we can make changes to our CORS configuration for better performance. After that, we can clear the cache using Artisan:

   php artisan config:clear

   And then re-cache the configuration:

   php artisan config:cache

Furthermore, if our API is meant to be accessible from multiple origins, we can use proper authentication and authorization mechanisms to secure our API endpoints.
