驱动支持

安装

安装此扩展程序的首选方法是通过 composer.

编辑运行

php composer.phar require --prefer-dist yiiplus/yii2-websocket "^1.0.0"

或添加配置到项目目录下的composer.json文件的 require 部分

"yiiplus/yii2-websocket": "^1.0.0"

基本使用

每个 channel 的功能都需要定义一个单独的类。例如,如果你需要为指定客户端推送一条消息,则该类可能如下所示:

namespace xxx\channels;

class PushMessageChannel extends BaseObject implements \yiiplus\websocket\ChannelInterface
{
	public function execute($fd, $data)
	{
		return [
			$fd, // 第一个参数返回客户端ID,多个以数组形式返回
			$data // 第二个参数返回需要返回给客户端的消息
		];
	}

	public function close($fd)
	{
		return;
	}
}

以下是从客户端发送消息的方法:

Yii::$app->websocket->send(['channel' => 'push-message', 'message' => '用户 xxx 送了一台飞机!']);

执行任务的确切方式取决于使用的驱动程序。 大多数驱动程序可以使用控制台命令运行,组件需要在应用程序中注册。

此命令启动一个守护进程,该守护进程维护一个 WebSocket Server,根据客户端发来的数据,处理相关 channel 的任务:

yii websocket/start
