实现laravel 插入操作日志到数据库的方法

<?php

namespace App\Http\Middleware;

use App\User;
use Closure;
use Illuminate\Support\Facades\Auth;

class OperationLog
{
  /
    Handle an ining request.
   
    @param \Illuminate\Http\Request $request
    @param \Closure $next
    @return mixed
   /
  public function handle($request, Closure $next)
  {
    $input = $request->all(); //操作的内容
    $path = $request->path(); //操作的路由
    $method = $request->method(); //操作的方法
    $ip = $request->ip(); //操作的IP
    $usernum = $request->usernum; //操作人(要自己获取)
    self::writeLog($usernum,$input,$path,$method,$ip);

    return $next($request);
  }
  public function writeLog($usernum,$input,$path,$method,$ip){

    $user = User::where('usernum',$usernum)->first();

    if($user) {
      $user_id = $user->userid;
    }

    $log = new \App\Models\OperationLog();
    $log->setAttribute('user_id', $user_id);
    $log->setAttribute('path', $path);
    $log->setAttribute('method', $method);
    $log->setAttribute('ip', $ip);
    $log->setAttribute('input', json_encode($input, JSON_UNESCAPED_UNICODE));
    $log->save();
  }
}

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class OperationLog extends Model
{

  //定义表
  protected $table = "operation_log";

  //定义主键
  protected $primaryKey = "id";
}

  The application's global HTTP middleware stack.
 
  这些中间件是在对应用程序的每次请求中运行的
 
  @var array

protected $middleware = [
    .......,
    .......,
    .......,
    \App\Http\Middleware\OperationLog::class,
  ];
