Laravel框架实现利用中间件进行操作日志记录功能

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['admin_uid'] = $user_id;
    if('GET' != $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 = '';
      $log->input = json_encode($input, JSON_UNESCAPED_UNICODE);
      $log->save();  # 记录日志
    }
    return $next($request);
  }
}

protected $middlewareGroups = [
    'web' => [
      ...
      \App\Http\Middleware\AdminOperationLog::class,
      ...
    ],
    'api' => [
      'throttle:60,1',
      'bindings',
    ],
  ];
