这个是Api下的index

<?php


namespace App\HttpController\Api;

use App\HttpController\Api\Base;
use EasySwoole\Component\Di;


class Index extends Base
{

    public function video()
    {
        //$config =  new \EasySwoole\Mysqli\Config(config::getInstance()->getConf('MYSQL'));
        $db = Di::getInstance()->get('MYSQL');
        $db->queryBuilder()->getOne('video');
        $result = $db->execBuilder();
        $this->writeJson('201', 'ok', $result);
    }

    public function nihao()
    {
        //$this->response()->write('hhhhhh');
        return $this->writeJson('101', 'ok');
    }
}

这个是Base

<?php
