本文实例讲述了Laravel框架实现利用监听器进行sql语句记录功能。分享给大家供大家参考,具体如下:

利用监听器进行sql语句记录

1、监听sql语句的事件类已经定义,直接创建监听器类即可:


# 监听sql
make:listener QueryListener --event=Illuminate\Database\Events\QueryExecuted

2、监听器类代码

./app/Listeners/QueryListener.php


<?php
namespace App\Listeners;
use Illuminate\Database\Events\QueryExecuted;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use App\Http\Models\OperationLog;
class QueryListener
{
 /**
 * Create the event listener.
 *
 * @return void
 */
 public function __construct()
 {
 //
 }
 /**
 * Handle the event.
 *
 * @param QueryExecuted $event
 * @return void
 */
 public function handle(QueryExecuted $event)
 {
 $sql = str_replace("?", "'%s'", $event->sql);
 $log = vsprintf($sql, $event->bindings);
 # 此处$uid定义是依赖于中间件记录操作日志代码
 $uid = isset($_SERVER['admin_uid']) ? $_SERVER['admin_uid'] : 0;
 if('select' != substr($log , 0 , 6)){
 if('insert into `operationLog`' != substr($log , 0 , 26)){
 $OperationLog = new OperationLog();
 $OperationLog->uid = $uid;
 $OperationLog->sql = $log;
 $OperationLog->input = '';
 $OperationLog->save();
 }
 }
 }
}

3、引入监听器

./app/Providers/EventServiceProvider.php


protected $listen = [
 ...
 \Illuminate\Database\Events\QueryExecuted::class => [
 'App\Listeners\QueryListener'
 ],
 ...
 ];

此时进行操作时就会记录sql日志
