How to Redirect All Laravel 5 Requests to HTTPS with Domain Exceptions?

Laravel 5: Enforce HTTPS Redirection

Question: How do I redirect all requests to HTTPS in a Laravel 5 application, while allowing exceptions for specific domains?

Answer:

To enforce HTTPS redirection, you can utilize a Middleware class. Here's how:

namespace MyApp\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\App;

class HttpsProtocol
{
    public function handle($request, Closure $next)
    {
        // In production environment, redirect non-secure requests
        if (!$request->secure() && App::environment() === 'production') {
            return redirect()->secure($request->getRequestUri());
        }

        return $next($request);
    }
}

Application:

Register the middleware in the Kernel.php file:

protected $middleware = [
    ...
    'MyApp\Http\Middleware\HttpsProtocol',
];

Cloudflare Configuration:

If you're using Cloudflare, you may encounter a redirect loop. To resolve this:

1. Add the following line to your middleware:

   $request->setTrustedProxies([$request->getClientIp()]);

   Copy after login

2. In Cloudflare's control panel, create a new Page Rule:

   • Match URL: *
   • Settings: Always Use HTTPS

Laravel v5.3 and Later:

For Laravel v5.3 and later, simply include the middleware in the web group:

protected $middlewareGroups = [
    'web' => [
        ...
        'MyApp\Http\Middleware\HttpsProtocol'
    ],
];

Other Notes:

• Ensure that your SSL is properly configured for the domains you specify.
• The environment you redirect from (HTTP) must be different from the production environment (HTTPS).
• You can further fine-tune the middleware behavior by checking the request domain or other factors.
