(要求Workerman版本>=3.3.0)

基于Worker的多进程(分布式集群)推送系统

start.php

<?php
use Workerman\Worker;
require_once './Workerman/Autoloader.php';
require_once './Channel/src/Server.php';
require_once './Channel/src/Client.php';

// 初始化一个Channel服务端
$channel_server = new Channel\Server('0.0.0.0', 2206);

// websocket服务端
$worker = new Worker('websocket://0.0.0.0:4236');
$worker->count=2;
$worker->name = 'pusher';
$worker->onWorkerStart = function($worker)
{
    // Channel客户端连接到Channel服务端
    Channel\Client::connect('127.0.0.1', 2206);
    // 以自己的进程id为事件名称
    $event_name = $worker->id;
    // 订阅worker->id事件并注册事件处理函数
    Channel\Client::on($event_name, function($event_data)use($worker){
        $to_connection_id = $event_data['to_connection_id'];
        $message = $event_data['content'];
        if(!isset($worker->connections[$to_connection_id]))
        {
            echo "connection not exsits\n";
            return;
        }
        $to_connection = $worker->connections[$to_connection_id];
        $to_connection->send($message);
    });

    // 订阅广播事件
    $event_name = '广播';
    // 收到广播事件后向当前进程内所有客户端连接发送广播数据
    Channel\Client::on($event_name, function($event_data)use($worker){
        $message = $event_data['content'];
        foreach($worker->connections as $connection)
        {
            $connection->send($message);
        }
    });
};

$worker->onConnect = function($connection)use($worker)
{
    $msg = "workerID:{$worker->id} connectionID:{$connection->id} connected\n";
    echo $msg;
    $connection->send($msg);
};

// 用来处理http请求，向任意客户端推送数据，需要传workerID和connectionID
$http_worker = new Worker('http://0.0.0.0:4237');
$http_worker->name = 'publisher';
$http_worker->onWorkerStart = function()
{
    Channel\Client::connect('127.0.0.1', 2206);
};
$http_worker->onMessage = function($connection, $data)
{
    $connection->send('ok');
    if(empty($_GET['content'])) return;
    // 是向某个worker进程中某个连接推送数据
    if(isset($_GET['to_worker_id']) && isset($_GET['to_connection_id']))
    {
        $event_name = $_GET['to_worker_id'];
        $to_connection_id = $_GET['to_connection_id'];
        $content = $_GET['content'];
        Channel\Client::publish($event_name, array(
           'to_connection_id' => $to_connection_id,
           'content'          => $content
        ));
    }
    // 是全局广播数据
    else
    {
        $event_name = '广播';
        $content = $_GET['content'];
        Channel\Client::publish($event_name, array(
           'content'          => $content
        ));
    }
};

Worker::runAll();

测试 （假设都是本机127.0.0.1运行）

1、运行服务端

 php start.php start
Workerman[start.php] start in DEBUG mode
----------------------- WORKERMAN -----------------------------
Workerman version:3.2.7          PHP version:5.4.37
------------------------ WORKERS -------------------------------
user          worker         listen                    processes status
root          ChannelServer  text://0.0.0.0:2206        1         [OK]
root          pusher         websocket://0.0.0.0:4236   2         [OK]
root          publisher      http://0.0.0.0:4237        1         [OK]
----------------------------------------------------------------
Press Ctrl-C to quit. Start success.

2、客户端连接服务端

打开chrome浏览器，按F12打开调试控制台，在Console一栏输入(或者把下面代码放入到html页面用js运行)

// 假设服务端ip为127.0.0.1，测试时请改成实际服务端ip
ws = new WebSocket("ws://127.0.0.1:4236");
ws.onmessage = function(e) {
    alert("收到服务端的消息：" + e.data);
};

3、通过调用http接口推送

url访问 http://127.0.0.1:4237/?content={$content} 向所有客户端连接推送$content数据

url访问http://127.0.0.1:4237/?to_worker_id={$worker_id}&to_connection_id={$connection_id}&content={$content}向某个worker进程中的某个客户端连接推送$content数据

注意：测试时把127.0.0.1 {$worker_id} {$connection_id}和{$content} 换成实际值
