(要求Workerman版本>=3.3.0)

基于Worker的多進(jìn)程(分布式集群)推送系統(tǒng)，集群群發(fā)、集群廣播。

start_channel.php
整個(gè)系統(tǒng)只能部署一個(gè)start_channel服務(wù)。假設(shè)運(yùn)行在192.168.1.1。

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

// 初始化一個(gè)Channel服務(wù)端
$channel_server = new Channel\Server('0.0.0.0', 2206);

Worker::runAll();

start_ws.php
整個(gè)系統(tǒng)可以部署多個(gè)start_ws服務(wù)，假設(shè)運(yùn)行在 192.168.1.2和192.168.1.3 兩臺(tái)服務(wù)器上。

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

// websocket服務(wù)端
$worker = new Worker('websocket://0.0.0.0:4236');
$worker->count=2;
$worker->name = 'pusher';
$worker->onWorkerStart = function($worker)
{
    // Channel客戶端連接到Channel服務(wù)端
    Channel\Client::connect('192.168.1.1', 2206);
    // 以自己的進(jìn)程id為事件名稱
    $event_name = $worker->id;
    // 訂閱worker->id事件并注冊(cè)事件處理函數(shù)
    Channel\Client::on($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 exists\n";
            return;
        }
        $to_connection = $worker->connections[$to_connection_id];
        $to_connection->send($message);
    });

    // 訂閱廣播事件
    $event_name = '廣播';
    // 收到廣播事件后向當(dāng)前進(jìn)程內(nèi)所有客戶端連接發(fā)送廣播數(shù)據(jù)
    Channel\Client::on($event_name, function($event_data)use($worker){
        $message = $event_data['content'];
        foreach($worker->connections as $connection)
        {
            $connection->send($message);
        }
    });
};

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

start_http.php
整個(gè)系統(tǒng)可以部署多個(gè)start_http服務(wù)，假設(shè)運(yùn)行在 192.168.1.4和192.168.1.5 兩臺(tái)服務(wù)器上。

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

// 用來處理http請(qǐng)求，向任意客戶端推送數(shù)據(jù)，需要傳workerID和connectionID
$http_worker = new Worker('http://0.0.0.0:4237');
$http_worker->name = 'publisher';
$http_worker->onWorkerStart = function()
{
    Channel\Client::connect('192.168.1.1', 2206);
};
$http_worker->onMessage = function(TcpConnection $connection, $request)
{
    // 兼容workerman4.x 5.x
    if (!is_array($request)) {
        $get = $request->get();
    }
    $connection->send('ok');
    if(empty($get['content'])) return;
    // 是向某個(gè)worker進(jìn)程中某個(gè)連接推送數(shù)據(jù)
    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
        ));
    }
    // 是全局廣播數(shù)據(jù)
    else
    {
        $event_name = '廣播';
        $content = $get['content'];
        Channel\Client::publish($event_name, array(
           'content'          => $content
        ));
    }
};

Worker::runAll();

測(cè)試

1、運(yùn)行個(gè)個(gè)服務(wù)器上的服務(wù)

2、客戶端連接服務(wù)端

打開chrome瀏覽器，按F12打開調(diào)試控制臺(tái)，在Console一欄輸入(或者把下面代碼放入到html頁(yè)面用js運(yùn)行)

// 也可以連ws://192.168.1.3:4236
ws = new WebSocket("ws://192.168.1.2:4236");
ws.onmessage = function(e) {
    alert("收到服務(wù)端的消息：" + e.data);
};

3、通過調(diào)用http接口推送

url訪問 http://192.168.1.4:4237/?content={$content} 或者 http://192.168.1.5:4237/?content={$content}向所有客戶端連接推送$content數(shù)據(jù)

url訪問 http://192.168.1.4:4237/?to_worker_id={$worker_id}&to_connection_id={$connection_id}&content={$content} 或者http://192.168.1.5:4237/?to_worker_id={$worker_id}&to_connection_id={$connection_id}&content={$content} 向某個(gè)worker進(jìn)程中的某個(gè)客戶端連接推送$content數(shù)據(jù)

注意：測(cè)試時(shí)把 {$worker_id} {$connection_id} 和{$content} 換成實(shí)際值
