+# Channel
+基于订阅的多进程通讯组件，用于workerman进程间通讯或者服务器集群通讯，类似redis订阅发布机制。基于workerman开发。
+
+Channel 提供两种通讯形式，分别是发布订阅的事件机制和消息队列机制。
+
+它们的主要区别是：
+- 事件机制是消息发出后，所有订阅该事件的客户端都能收到消息。
+- 消息队列机制是消息发出后，所有订阅该消息的客户端只有一个会收到消息，如果客户端忙消息会进行排队直到有客户端闲置后重新取到消息。
+- 需要注意的是 Channel 只是提供一种通讯方式，本身并不提供消息确认、重试、延迟、持久化等功能，请根据实际情况合理使用。

+# 手册地址
+[Channel手册](http://doc.workerman.net/components/channel.html)
+
+# 服务端
+```php
+use Workerman\Worker;
+
+//Tcp 通讯方式
+$channel_server = new Channel\Server('0.0.0.0', 2206);

+//$channel_server = new Channel\Server('unix:///tmp/workerman-channel.sock');
+
+if(!defined('GLOBAL_START'))

+# phpsocket.io手册
+
+## 安装
+请使用composer集成phpsocket.io。
+
+脚本中引用vendor中的autoload.php实现SocketIO相关类的加载。例如
+```php
+require_once '/你的vendor路径/autoload.php';
+```
+
+## 服务端和客户端连接
+**创建一个SocketIO服务端**
+```php
+<?php
+require_once __DIR__ . '/vendor/autoload.php';
+use Workerman\Worker;
+use PHPSocketIO\SocketIO;
+
+// 创建socket.io服务端，监听3120端口
+$io = new SocketIO(3120);
+// 当有客户端连接时打印一行文字
+$io->on('connection', function($socket)use($io){
+  echo "new connection coming\n";
+});
+
+Worker::runAll();
+```
+**客户端**
+```javascript
+<script src='https://cdn.bootcss.com/socket.io/2.0.3/socket.io.js'></script>
+<script>
+// 如果服务端不在本机，请把127.0.0.1改成服务端ip
+var socket = io('http://127.0.0.1:3120');
+// 当连接服务端成功时触发connect默认事件
+socket.on('connect', function(){
+    console.log('connect success');
+});
+</script>
+```
+
+## 自定义事件
+socket.io主要是通过事件来进行通讯交互的。
+
+socket连接除了自带的connect，message，disconnect三个事件以外，在服务端和客户端开发者可以自定义其它事件。
+
+服务端和客户端都通过emit方法触发对端的事件。
+
+例如下面的代码在服务端定义了一个```chat message```事件，事件参数为```$msg```。
+```php
+<?php
+require_once __DIR__ . '/vendor/autoload.php';
+use Workerman\Worker;
+use PHPSocketIO\SocketIO;
+
+$io = new SocketIO(3120);
+// 当有客户端连接时
+$io->on('connection', function($socket)use($io){
+  // 定义chat message事件回调函数
+  $socket->on('chat message', function($msg)use($io){
+    // 触发所有客户端定义的chat message from server事件
+    $io->emit('chat message from server', $msg);
+  });
+});
+Worker::runAll();
+```
+
+客户端通过下面的方法触发服务端的chat message事件。
+```javascript
+<script src='//cdn.bootcss.com/socket.io/1.3.7/socket.io.js'></script>
+<script>
+// 连接服务端
+var socket = io('http://127.0.0.1:3120');
+// 触发服务端的chat message事件
+socket.emit('chat message', '这个是消息内容...');
+// 服务端通过emit('chat message from server', $msg)触发客户端的chat message from server事件
+socket.on('chat message from server', function(msg){
+    console.log('get message:' + msg + ' from server');
+});
+</script>
+```
+
+## workerStart事件
+phpsocket.io提供了workerStart事件回调，也就是当进程启动后准备好接受客户端链接时触发的回调。
+一个进程生命周期只会触发一次。可以在这里设置一些全局的事情，比如开一个新的Worker端口等等。
+```php
+require_once __DIR__ . '/vendor/autoload.php';
+use Workerman\Worker;
+use PHPSocketIO\SocketIO;
+
+$io = new SocketIO(9120);
+
+// 监听一个http端口，通过http协议访问这个端口可以向所有客户端推送数据(url类似http://ip:9191?msg=xxxx)
+$io->on('workerStart', function()use($io) {
+    $inner_http_worker = new Worker('http://0.0.0.0:9191');
+    $inner_http_worker->onMessage = function($http_connection, $data)use($io){
+        if(!isset($_GET['msg'])) {
+            return $http_connection->send('fail, $_GET["msg"] not found');
+        }
+        $io->emit('chat message', $_GET['msg']);
+        $http_connection->send('ok');
+    };
+    $inner_http_worker->listen();
+});
+
+// 当有客户端连接时
+$io->on('connection', function($socket)use($io){
+  // 定义chat message事件回调函数
+  $socket->on('chat message', function($msg)use($io){
+    // 触发所有客户端定义的chat message from server事件
+    $io->emit('chat message from server', $msg);
+  });
+});
+
+Worker::runAll();
+```
+phpsocket.io启动后开内部http端口通过phpsocket.io向客户端推送数据参考 [web-msg-sender](http://www.workerman.net/web-sender)。
+
+## 分组
+socket.io提供分组功能，允许向某个分组发送事件，例如向某个房间广播数据。
+
+1、加入分组（一个连接可以加入多个分组）
+```php
+$socket->join('group name');
+```
+2、离开分组（连接断开时会自动从分组中离开）
+```php
+$socket->leave('group name');
+```
+
+## 向客户端发送事件的各种方法
+$io是SocketIO对象。$socket是客户端连接
+
+$data可以是数字和字符串，也可以是数组。当$data是数组时，客户端会自动转换为javascript对象。
+
+同理如果客户端向服务端emit某个事件传递的是一个javascript对象，在服务端接收时会自动转换为php数组。
+
+1、向当前客户端发送事件
+```php
+$socket->emit('event name', $data);
+```
+2、向所有客户端发送事件
+```php
+$io->emit('event name', $data);
+```
+3、向所有客户端发送事件，但不包括当前连接。
+```php
+$socket->broadcast->emit('event name', $data);
+```
+
+4、向某个分组的所有客户端发送事件
+```php
+$io->to('group name')->emit('event name', $data);
+```
+
+## 获取客户端ip
+```php
+$io->on('connection', function($socket)use($io){
+        var_dump($socket->conn->remoteAddress);
+});
+```
+
+## 关闭链接
+```php
+$socket->disconnect();
+```
+
+## 限制连接域名
+当我们想指定特定域名的页面才能连接，可以用$io->origins方法来设置域名白名单。
+```php
+$io = new SocketIO(2020);
+$io->origins('http://example.com:8080');
+```
+多个域名时用空格分隔，类似
+```php
+$io = new SocketIO(2020);
+$io->origins('http://workerman.net http://www.workerman.net');
+```
+
+## 支持SSL(https wss)
+SSL支持有两种方法，workerman原生和nginx代理
+### workerman原生支持
+SSL 要求workerman>=3.3.7 phpsocket.io>=1.1.1
+
+```php
+<?php
+require_once __DIR__ . '/vendor/autoload.php';
+use Workerman\Worker;
+use PHPSocketIO\SocketIO;
+
+// 传入ssl选项，包含证书的路径
+$context = array(
+    'ssl' => array(
+        'local_cert'  => '/your/path/of/server.pem',
+        'local_pk'    => '/your/path/of/server.key',
+        'verify_peer' => false,
+    )
+);
+$io = new SocketIO(2120, $context);
+
+$io->on('connection', function($socket)use($io){
+  echo "new connection coming\n";
+});
+
+Worker::runAll();
+```
+**注意：**<br>
+1、证书是要验证域名的，所以客户端链接时要指定域名才能顺利的建立链接。<br>
+2、客户端连接时不能再用http方式，要改成https类似下面这样。
+```javascript
+<script>
+var socket = io('https://yoursite.com:2120');
+//.....
+</script>
+```
+### nginx代理SSL
+
+**前提条件及准备工作：**
+
+1、已经安装nginx，版本不低于1.3
+
+2、假设phpsocket.io监听的是2120端口
+
+3、已经申请了证书（pem/crt文件及key文件）放在了/etc/nginx/conf.d/ssl下
+
+4、打算利用nginx开启443端口对外提供ssl代理服务（端口可以根据需要修改）
+
+**nginx配置类似如下：**
+```
+server {
+  listen 443;
+
+  ssl on;
+  ssl_certificate /etc/ssl/server.pem;
+  ssl_certificate_key /etc/ssl/server.key;
+  ssl_session_timeout 5m;
+  ssl_session_cache shared:SSL:50m;
+  ssl_protocols SSLv3 SSLv2 TLSv1 TLSv1.1 TLSv1.2;
+  ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
+
+  location /socket.io
+  {
+    proxy_pass http://127.0.0.1:2120;
+    proxy_http_version 1.1;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection "Upgrade";
+    proxy_set_header X-Real-IP $remote_addr;
+  }
+
+  # location / {} 站点的其它配置...
+}
+```
+**注意：**<br>
+1、证书是要验证域名的，所以客户端链接时要指定域名才能顺利的建立链接。<br>
+2、客户端连接时不能再用http方式，要改成https类似下面这样。
+```javascript
+<script>
+var socket = io('https://yoursite.com');
+//.....
+</scrip
