在asp.net中实现post发送数据
下面的代码实现了与以前xmlhttp类似的功能。代码如下：
httpsenddata.aspx
<%@ page language="<a href="http://dev.21tx.com/do.net/csharp/" target="_blank">c#</a>"%>
<%@ import namespace = "system"%>
<%@ import namespace = "system.collections"%>
<%@ import namespace = "system.<a href="http://dev.21tx.com/web/" target="_blank">web</a>"%>
<%@ import namespace = "system.web.ui"%>
<%@ import namespace = "system.web.ui.<a href="http://dev.21tx.com/do.net/as.net/webcontrols/" target="_blank">webcontrols</a>"%>
<%@ import namespace = "system<a href="http://dev.21tx.com/do.net/" target="_blank">.net</a>"%>
<%@ 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://<a href="http://dev.21tx.com/web/xml/" target="_blank">xml</a>.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">
