用C#和js实现xmlHttp发送cookies

function XmlHttpHelper(){}

XmlHttpHelper.__getXmlHttpObj = function()
{
try
{
return new ActiveXObject("MSXML2.XMLHTTP");
}
catch(e)
{
try
{
return new XMLHttpRequest();
}
catch(ee)
{
throw(new Error(-1, "无法创建XMLHTTP对象。"));
}
}
};

//
// 使用XMLHTTP和远程服务器通信。
//
// async 是否为异步方式：true/false
// httpMethod http方法："post"/"get"
// responseType 返回数据的类型："text"/"xml"/null
// url 请求的URL地址
// callback 异步操作完成时执行的回调函数
// postData post方式时发送的数据
//
XmlHttpHelper.transmit = function(async, httpMethod, responseType, url, callback, postData)
{
var xmlhttp = this.__getXmlHttpObj();
xmlhttp.open(httpMethod, url, async);

if(!async && httpMethod.toLowerCase() == "post")
{
xmlhttp.setRequestHeader('Content-Length', postData.length);
xmlhttp.setRequestHeader("content-type", "text/xml;charset=utf-8");

//xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
}

if(async)
{
xmlhttp.onreadystatechange = function()
{
if(xmlhttp.readyState == 4)
{
try
{
if(responseType != null)
{
if(responseType.toLowerCase() == "text")
callback(xmlhttp.responseText);
else if(responseType.toLowerCase() == "xml")
callback(xmlhttp.responseXML);
}
else
{
callback(null);
}
}
finally
{
xmlhttp = null;
}
}
}
xmlhttp.send(postData);
}
else
{
xmlhttp.send(postData);
if(xmlhttp.status == 200)
{
if(responseType != null)
{
if(responseType.toLowerCase() == "text")
return xmlhttp.responseText;
else if(responseType.toLowerCase() == "xml")
return xmlhttp.responseXML;
}
else
{
return null;
}
}
return null;
}
};

恩 很难

public string GetCookie(string KeyName)
{ string CookieName = "myCookie";//你的Cookie名称
HttpCookie myCookie = new HttpCookie(CookieName);
myCookie = HttpContext.Current.Request.Cookies[CookieName];

if (myCookie != null)
return myCookie.Values[KeyName];
else
return null;
}
//string myValue = GetCookie("KeyNname");
