How to solve the problem of Chinese garbled characters being transmitted during Ajax requests

This time I will show you how to solve the problem of transmitting Chinese garbled characters when Ajax requests. What are the precautions to solve the problem of transmitting Chinese garbled characters when Ajax requests. The following is a practical case, let's take a look.

I encountered a problem today, regarding the problem of garbled characters when transmitting Chinese in an ajax request.

The following code:

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);
}
});
}

If the above code only passes "&foderName="+folderName, the Chinese characters will be garbled. If it is converted twice through encodeURL, the Chinese character encoding will become similar to

The format of "%e6%b5%8b%eb%af%95". After converting to this format, transcode when obtaining, as shown below:

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);
}
}
}

After this conversion, the transmitted Chinese characters can be obtained.
