1.到workman官网下载GatewayWorker框架解压
下面是下载链接
https://www.workerman.net/download

2.将GatewayWorker/Applications/YourApp/start_gateway.php的

$gateway = new Gateway("tcp://0.0.0.0:8282");

改成

$gateway = new Gateway("Websocket://0.0.0.0:8282");

3.将GatewayWorker文件夹复制到tp5的vendor文件夹下
主要聊天的逻辑在\vendor\GatewayWorker\Applications\YourApp\下的Events.php
将下面代码粘到Events.php，将其覆盖

4.在TP5的application下的index/controller/index.php
控制器

namespace app\index\controller;

use think\Controller;

class Index extends Controller {

    public function index() {
        $formid = input('formid');
        $toid = input('toid');
        $this->assign('formid',$formid);
        $this->assign('toid',$toid);
        return $this->fetch();
    }
}

在TP5的application下的index/view/index/index.html
视图

双击TP5项目的\vendor\GatewayWorker下的start_for_win.bat启动

Linux系统切到\vendor\GatewayWorker下
以debug（调试）方式启动

php start.php start

以daemon（守护进程）方式启动

php start.php start -d

效果如下
