关于Ajax请求中传输中文乱码问题的解决方案

今天遇到一个问题，有关ajax 请求中传输中文，遇到乱码的问题。

如下代码：


function UpdateFolderInfoByCustId(folderId, folderName, custId) {
$.ajax({
type: "Post",
contentType: "application/x-www-form-urlencoded; charset=utf-8",
url: "http://localhost/CRM/Ashx/HandKBSucessCustomer.ashx?Method=UpdateCustomerByCustId&folderId=" 
+ folderId + "&folderName=" + encodeURI(encodeURI(folderName)) + "&custId=" + custId,
success: function (msg) {
alert(msg);
},
error: function (error) {
alert(error);
}
});
}

如上代码如果只是传“&foderName=”+folderName 的话，汉字就会产生乱码，如果经过encodeURL 转换两次的话，汉字编码会变为类似

“%e6%b5%8b%eb%af%95” 的格式。转换为这种格式之后，在获取的时候在转码，如下所示：


public void UpdateCustomerByCustId()
{
int folderId = Convert.ToInt32(Request["folderId"]);
string folderName = Request["folderName"];
string folderName2 = Convert.ToString(System.Web.HttpUtility.UrlDecode(folderName));
int custId = Convert.ToInt32(Request["custId"]);
bool res = false;
try
{
res = CustomerBusiness.UpdateCustomerByCustId(folderId, folderName2, custId);
}
catch (Exception ex)
{
throw;
}
Response.Write(res);
}
}
}
