在这里插入图片描述
index.php映射

//获取websocket链接
$this->assignconfig('socket_url', Config::get('websocket.url')?Config::get('websocket.url'):'ws://127.0.0.1:8282');//js中Config.socket_url就可以读取值

config.php

//配置websocket地址'websocket' => ['url' => 'ws://127.0.0.1:8282',//本地测试],

Backend.php 映射未读消息数量

//渲染消息总数量--判断是否登录if ($this->auth->id){$notice_num = Db::name('notice')->where(['role'=>1,'read'=>1,'uid'=>$this->auth->id])->count();$this->assign('notice', $notice_num);}
