这一上机实验的开发环境用的是jetbrain公司的phpstorm
上级步骤如下：
- 创建websocket服务端
<?php
$server = new swoole_websocket_server('127.0.0.1',9502);
function onopen($serv,$request)
{
echo "成功开启,已经为标示符".$request->fd."打开连接
";
}
$server->on('open','onopen');
$server->on('message',function(swoole_websocket_server $sw,$frame)
{
echo "opcode操作符---{$frame->opcode};操作数据---{$frame->data};fd数据来自句柄
---{$frame->fd};finish结束符号{$frame->finish}.
";
$sw->push($frame->fd,"推送的数据".$frame->data);//数据大小不过2M
});
$server->on('close',function($serv,$fd)
{
echo "来自{$fd}的通信结束
";
});
$server->start();
?>
- 准备一个html页面，并在页面中附上websocket协议脚本
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <meta name="description" content=""> <meta name="author" content=""> <link rel="icon" href="../../../../favicon.ico"> <title>websocket协议</title> <!-- Bootstrap core CSS --> <link href="../css/bootstrap.min.css" rel="stylesheet"> <!-- Custom styles for this template --> <link href="../mycss/sticky-footer-navbar.css" rel="stylesheet"> </head> <body> <header> <!-- Fixed navbar --> <nav class="navbar navbar-expand-md navbar-dark fixed-top bg-dark"> <a class="navbar-brand" href="#">Fixed navbar</a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarCollapse" aria-controls="navbarCollapse" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarCollapse"> <ul class="navbar-nav mr-auto"> <li class="nav-item active"> <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a> </li> <li class="nav-item"> <a class="nav-link" href="#">Link</a> </li> <li class="nav-item"> <a class="nav-link disabled" href="#">Disabled</a> </li> </ul> <form class="form-inline mt-2 mt-md-0"> <input class="form-control mr-sm-2" type="text" placeholder="Search" aria-label="Search"> <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button> </form> </div> </nav> </header> <!-- Begin page content --> <main role="main" class="container"> <h1 class="mt-5">Sticky footer with fixed navbar</h1> <p class="lead">Pin a fixed-height footer to the bottom of the viewport in desktop browsers with this custom HTML and CSS.

#精简---websocket部分
<script> var myurl = "ws://swsocks.com:9502"; var ws = new WebSocket(myurl); ws.onopen = function (evt) { ws.send("hello server"); console.log("向服务器打了个招呼") }; ws.onmessage = function (evt) { console.log("哟吼～服务器返回了数据"+evt.data); }; ws.onclose = function (evt) { console.log("关闭了面向服务器的连接"); } </script>
- 在phpstorm中运行写好的前端页面----右键点击要运行的html标签页，运行Run index.html
- 运行结果
- 如果运行多个前端页面实例将会显示更多句柄
成功开启,已经为标示符1打开连接 opcode操作符---1;操作数据---hello server;fd数据来自句柄---1;finish结束符号1. 成功开启,已经为标示符2打开连接 opcode操作符---1;操作数据---hello server;fd数据来自句柄---2;finish结束符号1. 成功开启,已经为标示符3打开连接 opcode操作符---1;操作数据---hello server;fd数据来自句柄---3;finish结束符号1. 成功开启,已经为标示符4打开连接 opcode操作符---1;操作数据---hello server;fd数据来自句柄---4;finish结束符号1.
- 优化，把服务端封装成类
class myswserver { const myip = '127.0.0.1'; const myport = 9502; public $serv = null; public function __construct() { $this->serv = new swoole_websocket_server('127.0.0.1',9502); $this->serv->on('open',[$this,'onopen']);#可能是swoole特有回调函数形式，可以对比php魔术方法call_user_func $this->serv->on('message',[$this,'onmessage']); $this->serv->on('close',[$this,'onclose']); $this->serv->start(); } public function onopen($serv,$request) { echo "连接{$request->fd}已经建立 "; } public function onmessage($serv,$frame) { echo "已经为{$frame->fd}建立了连接,并发送了数据{$frame->data},其退出标示符为{$frame->finish},其opcode为{$frame->opcode} "; $serv->push($frame->fd,$frame->data);//向客户端推送数据 } public function onclose($serv,$fd) { echo "关闭了{$fd}的连接 "; } } $serv = new myswserver(); $serv->start();
