Spatie Media Library http / https issue.

It looks like you're encountering an issue where the URLs generated by Spatie Media Library are using http instead of https, despite your APP_URL being set to https. This can happen due to a few reasons, such as incorrect configuration or the request not being recognized as secure.

Here are a few steps to troubleshoot and resolve this issue:

1. Ensure APP_URL is Correctly Set: Make sure that your .env file has the correct APP_URL set to https.

   APP_URL=https://staging.contenthead.com
   

2. Force HTTPS in the Application: You can force HTTPS in your application by adding the following code in the AppServiceProvider:

   use Illuminate\Support\Facades\URL;
   
   public function boot()
   {
       if (config('app.env') !== 'local') {
           URL::forceScheme('https');
       }
   }
   

3. Check the Web Server Configuration: Ensure that your web server (Nginx, Apache, etc.) is correctly configured to handle HTTPS requests and forward them to your Laravel application.

4. Check Trusted Proxies: If you're behind a load balancer or proxy, you might need to configure trusted proxies in your TrustProxies middleware. This ensures that Laravel correctly identifies the request as secure.

   namespace App\Http\Middleware;
   
   use Illuminate\Http\Middleware\TrustProxies as Middleware;
   use Fideloper\Proxy\TrustProxies as ProxyMiddleware;
   
   class TrustProxies extends Middleware
   {
       protected $proxies = '*';
   
       protected $headers = Request::HEADER_X_FORWARDED_ALL;
   }
   

5. Clear Cache: After making these changes, clear your application cache to ensure that the new settings take effect.

   php artisan config:cache
   php artisan route:cache
   php artisan view:cache
   

6. Verify URL Generation: Finally, verify that the URLs are being generated correctly by running a test in Tinker or by checking the output in your application.

Here is your updated index method with the above considerations:

public function index(Request $request) {
    $page_length = $request->page_length ?? 10;

    $items = MediaStore::search($request->search, 'created_at', 'DESC', ['name', 'description'])
        ->where('type', $request->type)
        ->with(['owner' => function ($query) {
            $query->select('id', 'first_name', 'last_name', 'email');
        }])
        ->paginate($page_length);

    // Now let's mutate each by adding media to it
    foreach ($items->items() as $item) {
        $media = $item->getMedia('*');
        if (count($media) > 0) {
            $item->url = $media[0]->getUrl();

            if ($item->type === 0) {
                $item->thumb = $media[0]->getUrl('thumb');
                $item->srcset = $media[0]->getSrcset();
            }
        }
    }

    return $items;
}

By following these steps, you should be able to ensure that the URLs generated by Spatie Media Library use https instead of http.
