安装swoole
以mac操作系统为例，如果你是mac新手，推荐阅读 程序员如何优雅使用mac
环境要求：php版本大于7.0
☁ swoole php -v
PHP 7.1.19 (cli) (built: Jun 25 2018 10:42:21) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2018 Zend Technologies

使用pecl安装swoole，安装过程中，会提示你是否需要安装某些扩展，可自主选择yes或no，如果是选择安装redis扩展，本机需要安装redis环境
pecl install swoole
选择redis扩展需要先安装相应的库
brew install redis
brew install hiredis
ide自动提示
默认情况下，phpstorm并不会自动提示swoole扩展包的相关函数，需要借助 swoole-ide-helper 实现自动提示
安装方法：
在项目的根目录执行：
composer require --dev "eaglewu/swoole-ide-helper:dev-master"
对于compoesr不熟悉的同学，请参阅这一次，真正掌握composer
接下来使用swoole搭建tcp，udp, http, websocket 服务，体验swoole的基本使用
tcp 服务
新建server.php
<?php
// 创建Server对象，监听 127.0.0.1:9501 端口
$serv = new swoole_server("127.0.0.01", 9501);
// 监听连接进入事件
$serv->on('connect', function ($serv, $fd) {
echo "Client: Connect.\n";
});
// 监听数据接收事件
$serv->on('receive', function ($serv, $fd, $from_id, $data) {
$serv->send($fd, "Server: " . $data);
});
// 监听连接关闭事件
$serv->on('close', function ($serv, $fd) {
echo "Client: Close.\n";
});
// 启动服务器
$serv->start();
服务端启动：
☁ server [master] ⚡ php server.php
[2018-04-26 09:08:59 @96245.0] TRACE Create swoole_server host=127.0.0.01, port=9501, mode=3, type=1
telnet 测试连接
☁ ~ telnet 127.0.0.1 9501
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
hello
Server: hello
退出telnet的方式：ctrl+], 然后再按 ctrl+d
udp 服务
新建udp_server.php
<?php
// 创建UDP Server对象
$serv = new swoole_server('127.0.0.1', 9502, SWOOLE_PROCESS, SWOOLE_SOCK_UDP);
// 监听数据接收事件
$serv->on('Packet', function ($serv, $data, $clientInfo) {
$serv->sendto($clientInfo['address'], $clientInfo['port'], 'Server ' . $data);
var_dump($clientInfo);
});
// 启动服务器
$serv->start();
☁ server [master] ⚡ php udp_server.php
[2018-04-26 09:18:10 @97828.0] TRACE Create swoole_server host=127.0.0.1, port=9502, mode=3, type=2
☁ ~ netcat -u 127.0.0.1 9502
hello
Server hello
http 服务
<?php
$http = new swoole_http_server('0.0.0.0', 9502);
$http->on('request', function ($request, $response) {
$response->header("Content-Type", "text/html; charset=utf-8");
$time = date('Y-m-d H:i:s', time());
$response->end("<h1>{$time}--这是swoole提供的http服务，修改代码后要重启服务才能生效</h1>");
});
$http->start();
☁ http php http_server.php
[2018-07-27 09:25:05 @53999.0] TRACE Create swoole_server host=0.0.0.0, port=9502, mode=3, type=1
浏览器访问：http://127.0.0.1:9502/
swoole-http
websocket 服务
ws 服务端
新建server.php文件
<?php
class Ws {
CONST HOST = "0.0.0.0";
CONST PORT = 8812;
public $ws = null;
public function __construct()
{
$this->ws = new swoole_websocket_server(self::HOST, self::PORT);
$this->ws->set(
[
'worker_num' => 2,
]
);
$this->ws->on('open', [$this, 'onOpen']);
$this->ws->on('message', [$this, 'onMessage']);
$this->ws->on('close', [$this, 'onClose']);
$this->ws->start();
}
/**
* 监听连接事件
* @param $ws
* @param $request
*/
public function onOpen($ws, $request)
{
echo "建立连接，客户端id：{$request->fd}\n";
}
/**
* 监听消息事件
* @param $ws
* @param $frame
*/
public function onMessage($ws, $frame)
{
echo "客户端发送的数据: {$frame->data}\n";
$pushData = date("Y-m-d H:i:s");
$ws->push($frame->fd, "服务端推送的数据: {$pushData}");
}
/**
* 监听关闭事件
* @param $ws
* @param $fd
*/
public function onClose($ws, $fd)
{
echo "客户端：{$fd} 关闭了连接\n";
}
}
$ws = new Ws();
ws 客户端
新建client.html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>websocket client</title>
</head>
<body>
<h1>swoole-websocket测试</h1>
<script>
var wsUrl = "ws://127.0.0.1:8812";
var websocket = new WebSocket(wsUrl);
websocket.onopen = function(evt) {
websocket.send("我是客户端，我要连接服务端");
console.log('连接成功');
}
websocket.onmessage = function(evt) {
console.log("接收到的服务端信息: " + evt.data);
}
websocket.onclose = function(evt) {
console.log("服务端关闭了");
}
websocket.onerror = function(evt, e) {
console.log("出错了: " + evt.data);
}
</script>
</body>
</html>
结果显示
开启ws服务：
ws server
浏览器打开ws_client.html文件:
ws client
