ajax 请求如何解决乱码

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); } }}

经此转换之后，即可获取到传输的汉字。
