Laravel5.3でSSL通信を強制する

Last updated at Posted at 2016-11-04

他のフレームワークではBefore Filterで実装するが、Laravelはmiddlewareで実装する。

$ php artisan make:middleware HttpsProtocol

本番とステージング環境でSSL通信を強制する。

<?php

namespace App\Http\Middleware;

use Closure;

class HttpsProtocol
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
      if (!$request->secure() && config('app.env') === 'production' || config('app.env') === 'staging') {
          return redirect()->secure($request->getRequestUri());
      }

      return $next($request);
    }
}

Kernelに登録

protected $middleware = [
  \App\Http\Middleware\HttpsProtocol::class,
];

ELBだとリダイレクトしまくる問題

ELBを噛ませていると、ELB(Port:443)→EC2(Port:80)のため、$request->secure()が効かなくなってしまう。EC2も443にしてしまう手もあるが、それができない場合は$_SERVER[“HTTP_X_FORWARDED_PROTO”]httpsであるかをチェックすればいいらしい。

if (config('app.env') === 'production' || config('app.env') === 'staging') {
  if ($_SERVER["HTTP_X_FORWARDED_PROTO"] != 'https') {
    return redirect()->secure($request->getRequestUri());
  }
}

続いてApp\Providers\AppServiceProviderのboot()に以下を追加
※5.4の場合はforceSchemaではなくforceSchemeにする必要がある

if (config('app.env') === 'production' || config('app.env') === 'staging') {
  \URL::forceSchema('https');
}

※ productionとstagingはELBが必ず噛んでいる想定です。ELBを噛んでいない場合は$_SERVER["HTTP_X_FORWARDED_PROTO"]の値が存在しないので、エラーになります。
