(要求Workerman版本>=3.3.0)
基于Worker的多进程分组推送系统
require_once __DIR__ . '/../Workerman/Autoloader.php';
require_once __DIR__ . '/Channel/src/Server.php';
require_once __DIR__ . '/Channel/src/Client.php';
use WorkermanWorker;
$channel_server = new ChannelServer('0.0.0.0', 2206);
$worker = new Worker('websocket://0.0.0.0:1234');
$worker->count = 8;
// 全局群组到连接的映射数组
$group_con_map = array();
$worker->onWorkerStart = function(){
// Channel客户端连接到Channel服务端
ChannelClient::connect('127.0.0.1', 2206);
// 监听全局分组发送消息事件
ChannelClient::on('send_to_group', function($event_data){
$group_id = $event_data['group_id'];
$message = $event_data['message'];
global $group_con_map;
var_dump(array_keys($group_con_map));
if (isset($group_con_map[$group_id])) {
foreach ($group_con_map[$group_id] as $con) {
$con->send($message);
}
}
});
};
$worker->onMessage = function($con, $data){
// 加入群组消息{"cmd":"add_group", "group_id":"123"}
// 或者 群发消息{"cmd":"send_to_group", "group_id":"123", "message":"这个是消息"}
$data = json_decode($data, true);
var_dump($data);
$cmd = $data['cmd'];
$group_id = $data['group_id'];
switch($cmd) {
// 连接加入群组
case "add_group":
global $group_con_map;
// 将连接加入到对应的群组数组里
$group_con_map[$group_id][$con->id] = $con;
// 记录这个连接加入了哪些群组,方便在onclose的时候清理group_con_map对应群组的数据
$con->group_id = isset($con->group_id) ? $con->group_id : array();
$con->group_id[$group_id] = $group_id;
break;
// 群发消息给群组
case "send_to_group":
// ChannelClient给所有服务器的所有进程广播分组发送消息事件
ChannelClient::publish('send_to_group', array(
'group_id'=>$group_id,
'message'=>$data['message']
));
break;
}
};
// 这里很重要,连接关闭时把连接从全局群组数据中删除,避免内存泄漏
$worker->onClose = function($con){
global $group_con_map;
// 遍历连接加入的所有群组,从group_con_map删除对应的数据
if (isset($con->group_id)) {
foreach ($con->group_id as $group_id) {
unset($group_con_map[$group_id][$con->id]);
}
if (empty($group_con_map[$group_id])) {
unset($group_con_map[$group_id]);
}
}
};
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[del.php] start in DEBUG mode
----------------------- WORKERMAN -----------------------------
Workerman version:3.4.2 PHP version:7.1.3
------------------------ WORKERS -------------------------------
user worker listen processes status
liliang ChannelServer frame://0.0.0.0:2206 1 [OK]
liliang none websocket://0.0.0.0:1234 12 [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://127.0.0.1:1234');
ws.onmessage = function(data){console.log(data.data)};
ws.onopen = function() {
ws.send('{"cmd":"add_group", "group_id":"123"}');
ws.send('{"cmd":"send_to_group", "group_id":"123", "message":"这个是消息"}');
};
