越来越多的项目需要用到实时消息的推送与接收,怎样用php实现最方便呢?我这里推荐大家使用GoEasy, 它是一款第三方推送服务平台,使用它的API可以轻松搞定实时推送!

浏览器兼容性:GoEasy推送 支持websocket 和polling两种连接方式,从而可以支持IE6及其以上的所有版本,同时还支持其它浏览器诸如Firefox, Chrome, Safari等等。

支持不同的开发语言:    GoEasy推送 提供了Restful API接口,无论你的后台程序用的是哪种语言都可以通过Restful API来实现后台实时推送。如:Java,PHP, C#, Ruby, Python, C, C++, ASP.NET,Node.js...

支持后台及前台推送: 后台用Restful API, 前台用goeasy.js; 运用十分简单!

 PHP Web实时消息后台服务器推送技术-GoEasy

 下面我介绍一下使用GoEasy的步骤:

 1. 你需要到goeasy官网上注册一个账号,并创建一个应用,应用创建好后系统会默认为它生成两个key: publish key和subscribe key

 2. 前台实时订阅及接收

    只需要引入goeasy.js,然后调用goeasy的subscribe方法订阅一个channel即可,订阅时无论是用publish key还是subscribe key都可以。通过subscribe的参数 onMessage的回调函数可以实时接收到消息。

 3. 前台实时推送

    还是需要引入goeasy.js(如果该页面已经引入了可不在引入),然后调用goeasy的publish方法向已订阅的channel上推送消息即可,推送时只能用publish key。

 4. 后台实时推送

     调用GoEasy Restful API, 用post方式访问http://goeasy.io/goeasy/publish, 同时还需要带上三个必要参数:

    appkey: publish key

    channel: 你订阅了的channel

   content: 推送内容

 就是这么简单。

下面我将之前写的一个小实例贴出来,里面用了Javascript 在web页面进行订阅,推送,接收,以及取消订阅的例子,里面的appkey用的是goeasy官方的demo 的appkey.
