A simple solution for using Laravel's rate-limiting on openshift.com

OpenshiftThrottleRequests.php

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Routing\Middleware\ThrottleRequests;

class OpenshiftThrottleRequests extends ThrottleRequests
{
    /**
     * Resolve request signature.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return string
     */
    protected function resolveRequestSignature($request)
    {
        if (! $request->route()) {
            throw new RuntimeException('Unable to generate fingerprint. Route unavailable.');
        }

        return sha1(
            implode('|', $request->route()->methods()).
            '|'.$request->route()->domain().
            '|'.$request->route()->uri().
            '|'.$request->header('x-forwarded-for', $request->ip())
        );
    }
}
