Laravel 5 - redirect to HTTPS

Working on my first Laravel 5 project and not sure where or how to place logic to force HTTPS on my app. The clincher here is that there are many domains pointing to the app and only two out of three use SSL (the third is a fallback domain, long story). So I'd like to handle this in my app's logic rather than .htaccess.

In Laravel 4.2 I accomplished the redirect with this code, located in filters.php:

App::before(function($request)
{
    if( ! Request::secure())
    {
        return Redirect::secure(Request::path());
    }
});

I'm thinking Middleware is where something like this should be implemented but I cannot quite figure this out using it.

Thanks!

UPDATE

If you are using Cloudflare like I am, this is accomplished by adding a new Page Rule in your control panel.

You can make it works with a Middleware class. Let me give you an idea.

namespace MyApp\Http\Middleware;

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

class HttpsProtocol {

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

            return $next($request); 
    }
}

Then, apply this middleware to every request adding setting the rule at Kernel.php file, like so:

protected $middleware = [
    'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
    'Illuminate\Cookie\Middleware\EncryptCookies',
    'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
    'Illuminate\Session\Middleware\StartSession',
    'Illuminate\View\Middleware\ShareErrorsFromSession',

    // appending custom middleware 
    'MyApp\Http\Middleware\HttpsProtocol'       

];

At sample above, the middleware will redirect every request to https if:

1. The current request comes with no secure protocol (http)
2. If your environment is equals to production. So, just adjust the settings according to your preferences.

Cloudflare

I am using this code in production environment with a WildCard SSL and the code works correctly. If I remove && App::environment() === 'production' and test it in localhost, the redirection also works. So, having or not a installed SSL is not the problem. Looks like you need to keep a very hard attention to your Cloudflare layer in order to get redirected to Https protocol.

Edit 23/03/2015

Thanks to @Adam Link's suggestion: it is likely caused by the headers that Cloudflare is passing. CloudFlare likely hits your server via HTTP and passes a X-Forwarded-Proto header that declares it is forwarding a HTTPS request. You need add another line in your Middleware that say...

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

...to trust the headers CloudFlare is sending. This will stop the redirect loop

Edit 27/09/2016 - Laravel v5.3

Just need to add the middleware class into web group in kernel.php file:

protected $middlewareGroups = [
    'web' => [
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,

        // here
        \MyApp\Http\Middleware\HttpsProtocol::class

    ],
];

Remember that web group is applied to every route by default, so you do not need to set web explicitly in routes nor controllers.

Edit 23/08/2018 - Laravel v5.7

• To redirect a request depending the environment you can use App::environment() === 'production'. For previous version was env('APP_ENV') === 'production'.
• Using \URL::forceScheme('https'); actually does not redirect. It just builds links with https:// once the website is rendered.

An other option that worked for me, in AppServiceProvider place this code in the boot method:

\URL::forceScheme('https');

The function written before forceSchema('https') was wrong, its forceScheme

Alternatively, If you are using Apache then you can use .htaccess file to enforce your URLs to use https prefix. On Laravel 5.4, I added the following lines to my .htaccess file and it worked for me.

RewriteEngine On

RewriteCond %{HTTPS} !on
RewriteRule ^.*$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

for laravel 5.4 use this format to get https redirect instead of .htaccess

namespace App\Providers;

use Illuminate\Support\Facades\URL;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {
        URL::forceScheme('https');
    }
}
