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：
复制代码 代码如下:
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：
复制代码 代码如下:
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);
        }
    }
}
经此转换之后，即可获取到传输的汉字。
