前言php

ThinkPHP即将迎来最新版本6.0，针对目前愈来愈流行Swoole，thinkphp也推出了最新的扩展think-swoole 3.0。html

介绍react

即将推出的tp6.0，已经适配swoole.并推出think-swoole 3.0，而且默认适配了socketio。和2.0版本在使用方法上面有些许不一样。web

Websocket 继承与Http，进行websocket链接以前须要一次HTTP请求，若是当期地址支持websocket则返回101，而后进行链接。也就是说并非个人服务支持websocket后，请求每一个链接地址均可以进行websocket链接，而是须要预先适配才能够链接。thinkphp

handler和parser大大方便了自定义websocket服务，默认系统集成socketio。

本文主要介绍如何使用socketio，这里假设你们有socketio有必定了解和使用基础。

socketIo默认会在请求地址后加相应的参数

同时，socketio默认状况下，会认为 http://url/socket.io/ 是支持websocket服务的地址。

而在tp-swoole3.0内部已经对该地址请求进行了处理

<?phpnamespace think\swoole\websocket\socketio;use think\Config;use think\Cookie;use think\Request;class Controller{    protected $transports = ['polling', 'websocket'];    public function upgrade(Request $request, Config $config, Cookie $cookie)
    {        if (!in_array($request->param('transport'), $this->transports)) {            return json(
                [                    'code'    => 0,                    'message' => 'Transport unknown',
                ],                400
            );
        }        if ($request->has('sid')) {
            $response = response('1:6');
        } else {
            $sid     = base64_encode(uniqid());
            $payload = json_encode(
                [                    'sid'          => $sid,                    'upgrades'     => ['websocket'],                    'pingInterval' => $config->get('swoole.websocket.ping_interval'),                    'pingTimeout'  => $config->get('swoole.websocket.ping_timeout'),
                ]
            );
            $cookie->set('io', $sid);
            $response = response('97:0' . $payload . '2:40');
        }        return $response->contentType('text/plain');
    }    public function reject(Request $request)
    {        return json(
            [                'code'    => 3,                'message' => 'Bad request',
            ],            400
        );
    }
}

TP6.0,插件注册采用了service方式进行了注册，可在tp-swoole 服务注册文件中查看路由注册信息,若是想自定义连接规则，则能够覆盖该路由。

    protected function createSwooleServer()

        $config     = $this->app->config;
        $host       = $config->get('swoole.server.host');

        $options = $config->get('swoole.server.options');        static::$server->set($options);
    }
}

Socketio默认使用demo

<!DOCTYPE html><html lang="en"><head>
    <meta charset="UTF-8">
    <title>Title</title>
    <script src="./static/js/socket.io.js"></script></head><body><script>
    const socket = io('http://localhost:808');
    socket.emit("test", "your message");
    socket.on("test",function(res){console.log(res)});</script></body></html>

Websocket路由配置方法

在app目录下新建websocket.php文件,其中须要注意，因为使用了反射，闭包参数名称不能随意定义，否则没法注入。第一个参数是websocket，是当前websocket的Server对象，第二个参数data是客户端发送的数据。其中socketio emit的第一个参数和Websocket::on的第一个参数一致，做为事件名称。

<?php/**
 * Author:Xavier Yang
 * Date:2019/6/5
 * Email:499873958@qq.com
 */use \think\swoole\facade\Websocket;
Websocket::on("test", function (\think\swoole\Websocket $websocket, $data) {    //var_dump($class);
    $websocket->emit("test", "asd");
});
Websocket::on("test1", function ($websocket, $data) {
    $websocket->emit("test", "asd");
});
Websocket::on("join", function (\think\swoole\Websocket $websocket, $data) {
    $websocket->join("1");
});

参考如上方法便可使用全新的websocket服务。固然tp-swoole3.0一样还有许多其余的新功能，这些功能须要你们去摸索尝试。我也会在接下来的文章中，一块儿与你们分享个人使用过程。
