安裝swoole

以mac操作系統(tǒng)為例，如果你是mac新手啥刻，推薦閱讀程序員如何優(yōu)雅使用mac

環(huán)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
    with Zend OPcache v7.1.19, Copyright (c) 1999-2018, by Zend Technologies

使用pecl安裝swoole应狱，安裝過程中绑嘹，會提示你是否需要安裝某些擴展郭脂，可自主選擇yes或no年碘，如果是選擇安裝redis擴展，本機需要安裝redis環(huán)境

pecl install swoole

選擇redis擴展需要先安裝相應(yīng)的庫

brew install redis
brew install hiredis

ide自動提示

默認情況下展鸡，phpstorm并不會自動提示swoole擴展包的相關(guān)函數(shù)屿衅，需要借助 swoole-ide-helper 實現(xiàn)自動提示

安裝方法：

在項目的根目錄執(zhí)行：

composer require --dev "eaglewu/swoole-ide-helper:dev-master"

對于compoesr不熟悉的同學(xué)，請參閱這一次莹弊，真正掌握composer

接下來使用swoole搭建tcp涤久，udp, http, websocket 服務(wù)，體驗swoole的基本使用

tcp 服務(wù)

新建server.php

<?php
// 創(chuàng)建Server對象忍弛，監(jiān)聽 127.0.0.1:9501 端口
$serv = new swoole_server("127.0.0.01", 9501);

// 監(jiān)聽連接進入事件
$serv->on('connect', function ($serv, $fd) {
    echo "Client: Connect.\n";
});

// 監(jiān)聽數(shù)據(jù)接收事件
$serv->on('receive', function ($serv, $fd, $from_id, $data) {
    $serv->send($fd, "Server: " . $data);
});

// 監(jiān)聽連接關(guān)閉事件
$serv->on('close', function ($serv, $fd) {
    echo "Client: Close.\n";
});

// 啟動服務(wù)器
$serv->start();

服務(wù)端啟動：

?  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 測試連接

?  ~  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 服務(wù)

新建udp_server.php

<?php
// 創(chuàng)建UDP Server對象
$serv = new swoole_server('127.0.0.1', 9502, SWOOLE_PROCESS, SWOOLE_SOCK_UDP);

// 監(jiān)聽數(shù)據(jù)接收事件
$serv->on('Packet', function ($serv, $data, $clientInfo) {
    $serv->sendto($clientInfo['address'], $clientInfo['port'], 'Server ' . $data);
    var_dump($clientInfo);
});

// 啟動服務(wù)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 服務(wù)

<?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}--這是swoole提供的http服務(wù)响迂，修改代碼后要重啟服務(wù)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

websocket 服務(wù)

ws 服務(wù)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();
    }


    /**

     * @param $ws
     * @param $request
     */
    public function onOpen($ws, $request)
    {
        echo "建立連接，客戶端id：{$request->fd}\n";
    }


    /**

     */
    public function onMessage($ws, $frame)
    {
        echo "客戶端發(fā)送的數(shù)據(jù): {$frame->data}\n";
        $pushData = date("Y-m-d H:i:s");
        $ws->push($frame->fd, "服務(wù)端推送的數(shù)據(jù): {$pushData}");
    }

    /**

     * @param $ws
     * @param $fd
     */
    public function onClose($ws, $fd)
    {
        echo "客戶端：{$fd} 關(guān)閉了連接\n";
    }
}

$ws = new Ws();
