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：

复制代码 代码如下:

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：

复制代码 代码如下:

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);

}

}

}

经此转换之后，即可获取到传输的汉字。
