workerman的使用方法

workerman是什么？

Workerman是一個異步事件驅動的PHP框架，具有高性能，可輕松構建快速，可擴展的網絡應用程序。支持HTTP，Websocket，SSL和其他自定義協議。支持libevent，HHVM，ReactPHP。

要求

PHP 5.3或更高版本
兼容POSIX的操作系統（Linux，OSX，BSD）
用于PHP的POSIX和PCNTL擴展

安裝

composer require workerman/workerman

基本用法

websocket服務器

<?php
require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;

// 創建一個Websocket服務器
$ws_worker = new Worker("websocket://0.0.0.0:2346");

$ws_worker->count = 4;

// 在新連接到來時發出
$ws_worker->onConnect = function($connection)
{
    echo "New connection\n";
 };

// 接收數據時發出
$ws_worker->onMessage = function($connection, $data)
{
    // Send hello $data
    $connection->send('hello ' . $data);
};

// 連接關閉時發出
$ws_worker->onClose = function($connection)
{
    echo "Connection closed\n";
};

// 運行worker
Worker::runAll();

http服務器

require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;

// #### http worker ####
$http_worker = new Worker("http://0.0.0.0:2345");

$http_worker->count = 4;

// 接收數據時發出
$http_worker->onMessage = function($connection, $data)
{
    //$_GET、$_POST、$_COOKIE、$_SESSION、$_SERVER、$_FILES都是可用的
    var_dump($_GET, $_POST, $_COOKIE, $_SESSION, $_SERVER, $_FILES);
    // 發送數據給客戶端
    $connection->send("hello world \n");
};

// 運行所有workers
Worker::runAll();

WebServer

require_once __DIR__ . '/vendor/autoload.php';
use Workerman\WebServer;
use Workerman\Worker;

// WebServer
$web = new WebServer("http://0.0.0.0:80");

$web->count = 4;

$web->addRoot('www.your_domain.com', '/your/path/Web');
$web->addRoot('www.another_domain.com', '/another/path/Web');

Worker::runAll();

TCP服務器

require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;

// #### 創建socket并監聽1234端口 ####
$tcp_worker = new Worker("tcp://0.0.0.0:1234");

$tcp_worker->count = 4;

//在新連接到來時發出
$tcp_worker->onConnect = function($connection)
{
    echo "New Connection\n";
};

// 接收數據時發出
$tcp_worker->onMessage = function($connection, $data)
{
    // 發送數據給客戶端
    $connection->send("hello $data \n");
};

// 在新連接到來時發出
$tcp_worker->onClose = function($connection)
{
    echo "Connection closed\n";
};

Worker::runAll();

啟用SSL

<?php
require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;

// SSL環境
$context = array(
    'ssl' => array(
        'local_cert'  => '/your/path/of/server.pem',
        'local_pk'    => '/your/path/of/server.key',
        'verify_peer' => false,
    )
);

// 創建一個帶有ssl的Websocket服務器。
$ws_worker = new Worker("websocket://0.0.0.0:2346", $context);

// 啟用SSL。WebSocket+SSL意味著安全的WebSocket (wss://)。
//類似的Https方法等等。
$ws_worker->transport = 'ssl';

$ws_worker->onMessage = function($connection, $data)
{
    // 發送hello $data
    $connection->send('hello ' . $data);
};

Worker::runAll();

自定義協議

Protocols/MyTextProtocol.php

namespace Protocols;
/**
 * 用戶定義的協議
*格式文本+“\ n”
 */
class MyTextProtocol
{
    public static function input($recv_buffer)
    {
        // 找到“\n”第一個出現的位置
        $pos = strpos($recv_buffer, "\n");
        // 不是一個完整的package。返回0，因為package的長度無法計算
        if($pos === false)
        {
            return 0;
        }
        // 返回package的長度
        return $pos+1;
    }

    public static function decode($recv_buffer)
    {
        return trim($recv_buffer);
    }

    public static function encode($data)
    {
        return $data."\n";
    }
}

require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;

// #### MyTextProtocol worker ####
$text_worker = new Worker("MyTextProtocol://0.0.0.0:5678");

$text_worker->onConnect = function($connection)
{
    echo "New connection\n";
};

$text_worker->onMessage =  function($connection, $data)
{
    // 發送數據給客戶端
    $connection->send("hello world \n");
};

$text_worker->onClose = function($connection)
{
    echo "Connection closed\n";
};

// 運行所有workers
Worker::runAll();

計時器

require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;
use Workerman\Lib\Timer;

$task = new Worker();
$task->onWorkerStart = function($task)
{
    // 2.5秒
    $time_interval = 2.5; 
    $timer_id = Timer::add($time_interval, 
        function()
        {
            echo "Timer run\n";
        }
    );
};

//運行
Worker::runAll();

AsyncTcpConnection（tcp / ws / text / frame等...）

require_once __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;
use Workerman\Connection\AsyncTcpConnection;

$worker = new Worker();
$worker->onWorkerStart = function()
{
    //客戶端Websocket協議。
    $ws_connection = new AsyncTcpConnection("ws://echo.websocket.org:80");
    $ws_connection->onConnect = function($connection){
        $connection->send('hello');
    };
    $ws_connection->onMessage = function($connection, $data){
        echo "recv: $data\n";
    };
    $ws_connection->onError = function($connection, $code, $msg){
        echo "error: $msg\n";
    };
    $ws_connection->onClose = function($connection){
        echo "connection closed\n";
    };
