Laravel 利用中间件进行操作日志记录

利用中间件进行操作日志记录过程：

1、创建中间件

php artisan make:middleware AdminOperationLog

2、生成了文件./app/Http/Middleware/AdminOperationLog.php

代码如下：

<?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);
    }
}

3、中间件引入 ./app/Http/Kernel.php

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

此时进行操作时就会记录操作日志
