网站程序在万网虚拟主机上用post方式向另一网站传递数据失败！郁闷中！

[zy44995]

网站用post方式向一短信接口传递数据，以实现在线发送手机短信功能：
private void sendsms(string userid,string password,string phonenumber,string msg)
{
string s = null;
try
{
string url = "http://www.xunsai.net:8000/?";
string param = null;
param = "user=" + userid + "&password=" + password + "&phonenumber=" + phonenumber + "&text=" + msg + "&charset=gb2312";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "POST";
request.AllowAutoRedirect = true;
request.ContentType = "text/html;charset=GB2312;";
NetworkCredential nc = new NetworkCredential(userid, password);
request.Credentials = nc;
byte[] data = Encoding.GetEncoding("GB2312").GetBytes(param);
request.ContentLength = data.Length;
Stream stream = request.GetRequestStream();
stream.Write(data, 0, data.Length);
stream.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("GB2312"));
s = sr.ReadToEnd();
response.Close();
}
catch (Exception e)
{
Page.ClientScript.RegisterStartupScript(this.GetType(), "", "<script>alert('" + e.Message + "');</script>");
return;
}
string sc = "已经成功提交";
if (s.Contains(sc))
{ Page.ClientScript.RegisterStartupScript(this.GetType(), "", "<script>alert('发送成功！');</script>"); }
else
{ Page.ClientScript.RegisterStartupScript(this.GetType(), "", "<script>alert('发送失败！');</script>"); }
}
在本机上调试一切正常，可以正常发送短信。但是把程序传到万网虚拟主机上后却失败，返回e.Message错误信息“无法连接远程服务器”

8000端口被屏蔽了估计

不会短信接口没有将8000端口屏蔽，通过直接在ie中输入url: http://www.xunsai.net:8000/?user=***&password=***....是可以发送短信的，并且在本机调试也可以正常发送的，与万网是否开放8000端口没任何关系！

你确定万网的服务器开了8000端口了？

接收方的端口可以肯定是一直打开的，你得确定发送方的端口是否打开
