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：

復制代碼 代碼如下:

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：

復制代碼 代碼如下:

 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);
        }
    }
}

經此轉換之后，即可獲取到傳輸的漢字。
