windows 搭建 swoole开发环境（官网已支持）

参考文章：https://zhuanlan.zhihu.com/p/628489045

1.下载：https://wenda-1252906962.file.myqcloud.com/dist/swoole-cli-v5.0.3-cygwin-x64.zip

2.解压后放到自己的目录：F:\work\swoole-cli-v5.0.3-cygwin-x64

3.添加系统变量：

4.编写server.php后端文件,index.html前端文件

<?php

//创建WebSocket Server对象，监听0.0.0.0:9502端口。
$ws = new Swoole\WebSocket\Server('0.0.0.0', 9502);

//监听WebSocket连接打开事件。
$ws->on('Open', function ($ws, $request) {
    echo "Message: {$request->fd} is in!\n";
    $ws->push($request->fd, "hello, welcome!xw\n");
});

//监听WebSocket消息事件。
$ws->on('Message', function ($ws, $frame) {
    echo "Message: {$frame->data}\n";
    $ws->push($frame->fd, "server: {$frame->data}");
});

//监听WebSocket连接关闭事件。
$ws->on('Close', function ($ws, $fd) {
    echo "client-{$fd} is closed\n";
});

$ws->start();
