下面是服务器端接收请求方法：
加载事件里：//对应方法StartPingbyte[] byts = new byte[Request.InputStream.Length];Request.InputStream.Read(byts, 0, byts.Length);string req = System.Text.Encoding.Default.GetString(byts);req = Server.UrlDecode(req);//下面是接收到的内容//<?xml version="1.0"?><params><title>????</title><content>?????base64???</content><verify=be10c510b5f4f082dbd4268820cde895></params>*/
