控制器代碼

<?php
namespace app\controller;

use app\model\Order;
use Illuminate\Database\QueryException;
use support\Db;
use support\Request;

class User
{
    public function index(Request $request)
    {
//        $data = Order::filter($request->all())->get();
//        $data = Order::where('id',1)->first();
        $data = Db::table('cz_order')->where('id','>',1)->first();
        return json($data);
    }
}

app/bootstrap/Report.php

<?php
namespace app\bootstrap;
use support\Db;
use Webman\Bootstrap;

class Report implements Bootstrap
{
    public static function start($worker)
    {
        echo "Report start被調用啦~\n";
        Db::listen(function(\Illuminate\Database\Events\QueryExecuted $query) {
            echo $query->sql. "\n";
        });
    }
}

config/bootstrap.php

<?php
return [
    support\bootstrap\Session::class,
    support\bootstrap\LaravelDb::class,
    \app\bootstrap\Report::class,
];
