下面的代码实现了与以前XMLHTTP类似的功能。代码如下：
HttpSendData.aspx
<![CDATA[
<%@ Page language="c#"%> <%@ Import Namespace = "System"%> <%@ Import Namespace = "System.Collections"%> <%@ Import Namespace = "System.Web"%> <%@ Import Namespace = "System.Web.UI"%> <%@ Import Namespace = "System.Web.UI.WebControls"%> <%@ Import Namespace = "System.Net"%> <%@ Import Namespace = "System.IO"%> <%@ Import Namespace = "System.Text"%> <!doctype HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" > <html> <head> <script runat="server"> void Button1_Click(object sender, System.EventArgs e) { string strTitle = TextBox1.Text; string strDesc = TextBox2.Text; Encoding encoding = Encoding.GetEncoding("GB2312"); string postData = "Title=" + strTitle; string strUrl = "http://xml.sz.luohuedu.net/HttpReceiveData.aspx"; postData += ("&Desc=" + strDesc); byte[] data = encoding.GetBytes(postData); // 准备请求... HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(strUrl); myRequest.Method = "POST"; myRequest.ContentType="application/x-www-form-urlencoded"; myRequest.ContentLength = data.Length; Stream newStream=myRequest.GetRequestStream(); // 发送数据 newStream.Write(data,0,data.Length); newStream.Close(); Response.Redirect("HttpSendData.aspx"); } </script> </head> <body> <form id="HTTPPost" method="post" runat="server"> 标题：<asp:TextBox id="TextBox1" runat="server"></asp:TextBox> <br /> 内容： <br /> <asp:TextBox id="TextBox2" runat="server" TextMode="MultiLine" Rows="10" Columns="100"></asp:TextBox> <br /> <asp:Button id="Button1" runat="server" Text=" 发 送 " onclick="Button1_Click"></asp:Button> </form> </body> </html>
]]>
HttpReceiveData.aspx
<![CDATA[

补充code：
private HttpWebRequest CreateRequest()
{
HttpWebRequest 请求=null;
// string aa=TxNetId();
请求=(HttpWebRequest)HttpWebRequest.Create(this._strUrl);//创建请求
请求.Accept = "*/*"; //接受任意文件
请求.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.1.4322)"; // 模拟使用IE在浏览
请求.AllowAutoRedirect = true;//这里不允许302
请求.CookieContainer =comm.cookie;//cookie容器，
请求.Referer="http://bbs.tiexue.net"; //当前页面的引用
//如果附带cookie 就发送
if ( this._cookiePost !=null)
{
System.Uri u =new Uri(_strUrl);
//doenet处理cookie的bug：请求的服务器和cookie的Host必须一直，否则不发送或获取！
//这里修改成一致！
foreach(System.Net.Cookie c in _cookiePost)
{
c.Domain= u.Host;
}
请求.CookieContainer.Add(_cookiePost);
}
//如果需要发送数据，就以Post方式发送
if (_strPostdata !=null && _strPostdata.Length>0)
{
// 请求.CookieContainer.Add(new Cookie("TxNet","","/","bbs.tiexue.net"));
请求.ContentType = "application/x-www-form-urlencoded";//作为表单请求
请求.Method = "POST";//方式就是Post
//发送http数据：朝请求流中写post的数据
byte[] b= this._encoding.GetBytes(this._strPostdata);
请求.ContentLength=b.Length;
System.IO.Stream sw=null;
try
{
sw=请求.GetRequestStream();
sw.Write(b,0,b.Length );
}
catch (System.Exception ex)
{
this._strErr=ex.Message;
}
finally
{
if (sw!=null){sw.Close();}
}
}
return 请求; //返回创建的请求对象
}
public string Proc()
{
HttpWebRequest 请求=CreateRequest();//请求
HttpWebResponse 响应=null;;
System.IO.StreamReader sr=null;
try
{
//这里得到响应
响应 =(HttpWebResponse)请求.GetResponse();
sr=new System.IO.StreamReader(响应.GetResponseStream(),this.encoding);
this._ResHtml=sr.ReadToEnd(); // 这里假定响应的都是html文本
}
catch (System.Exception ex)
{
this._strErr=ex.Message;//发生错误就返回空文本
return "";
}
finally
{
if (sr!=null){sr.Close();}
}
//状态码
this._strCode=响应.StatusCode.ToString();
if (this._strCode=="302") //如果是302重定向的话就返回新的地址。
{

}
//得到cookie

}

}
