今天遇到一個問題，有關ajax 請求中傳輸中文，遇到亂碼的問題。

如下代碼：

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);
??????? }
??? });
?}

如上代碼 如果只是傳“&foderName=”+folderName 的話，漢字就會產生亂碼，如果經過encodeURL 轉換兩次的話，漢字編碼會變為類似

“%e6%b5%8b%eb%af%95” 的格式。轉換為這種格式之后，在獲取的時候在轉碼，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);
??????? }
??? }
}

經此轉換之后，即可獲取到傳輸的漢字。
