Solution to ajax request garbled characters

This article describes how to solve ajax request Garbled text (Chinese Garbled text). For more information, see

Today, I encountered a problem with garbled characters concerning the transmission of Chinese Characters in ajax requests.

 

The following code:

The Code is as follows:

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 (folderName) + "& custId =" + custId,

Success: function (msg ){

Alert (msg );

},

Error: function (error ){

Alert (error );

}

});

}

 

 

If the above Code only transmits "& foderName =" + folderName, Chinese characters will produce garbled characters. If it is converted twice through encodeURL, the Chinese character encoding will become similar

 

"% E6 % b5 % 8b % eb % af % 95" format. After being converted to this format, transcoding is performed when obtaining it, as shown below:

The Code is as follows:

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 conversion, you can obtain the transmitted Chinese characters.
