Laravelフレームワークはミドルウェアを利用して操作ログ機能を実装

php artisan make:middleware AdminOperationLog

<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use App\Http\Models\OperationLog;
class AdminOperationLog
{
  /**
   * Handle an incoming request.
   *
   * @param \Illuminate\Http\Request $request
   * @param \Closure $next
   * @return mixed
   */
  public function handle($request, Closure $next)
  {
    $user_id = 0;
    if(Auth::check()) {
      $user_id = (int) Auth::id();
    }
    $_SERVER[&#39;admin_uid&#39;] = $user_id;
    if(&#39;GET&#39; != $request->method()){
      $input = $request->all();
      $log = new OperationLog(); # 提前创建表、model
      $log->uid = $user_id;
      $log->path = $request->path();
      $log->method = $request->method();
      $log->ip = $request->ip();
      $log->sql = &#39;&#39;;
      $log->input = json_encode($input, JSON_UNESCAPED_UNICODE);
      $log->save();  # 记录日志
    }
    return $next($request);
  }
}
