我的代码：

        {
            HttpHelper http = new HttpHelper();
            HttpItem item = new HttpItem()
            {

                URL = "http://api.buyer.vdian.com/wd_device_uploadStatus.do",

            item.Header.Add("wang", "2");//设置请求头信息（Header）
            item.Header.Add("x-requested-with", "XMLHttpRequest");  //主要就是这一句，赶集服务器只接受ajax请求。
            HttpResult result = http.GetHtml(item);
            string html = result.Html;
            debugwindow.AppendText(html);
            MessageBox.Show(html);




            SufeiNet_Test models=new SufeiNet_Test();

            models = (SufeiNet_Test)SerializerJsonHelper.JsonToObject(html, models);


            MessageBox.Show(models.result.ToString());
            MessageBox.Show(models.status.code.ToString());

        }
    }

现在就是密码很复杂，有谁有这方面的思路？
主要是实现，多帐号，一个登陆，签到！
