使用swoole进行消息推送通知，配合vb.net进行客户端开发一样爽[

导读：在以前的项目中，就曾听说过swoole的大名，想用来进行消息推送，但是当时只是有了初步的了解，并不敢大胆的运用到线上产品。所谓?识不足则多虑，威不足则多怒、所以就是怕，只能跟领导说了运用极光的推送功能，而且还说出了一定的理由，领导自然也只有相信了

　　第五步，使用vb.net实现客户端访问：

Public Class SynchronousSocketClient
Protected Shared port As Integer = 9501
Protected Shared host As String = "localhost"

如上是访问连接服务器的代码，触发代码则是在另一个页面进行的，界面如下：
