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
