Laravel Framework Realizes Operation Log Recording Using Middleware

In this paper, an example is given to describe the implementation of Laravel framework using middleware to record operation logs. Share it for your reference, as follows:

Operation logging process using middleware:

1. Create middleware

php artisan make:middleware AdminOperationLog

2. The file is generated./app/Http/Middleware/AdminOperationLog. php

The code is as follows:

<?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(); #  Create tables in advance, 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();  #  Record a log 
    }
    return $next($request);
  }
}

3. Middleware introduction./app/Http/Kernel. php

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

At this time, the operation log will be recorded when the operation is performed
