京东价格监控软件开发技术探讨三：使用C#模拟京东登录

使用C#模拟京东登录

京东模拟登录步骤
第一步：获取登录页面基础值
第二步：判断是否需要验证码
第三步：拼装提交信息
第四步：提交数据到指定服务
第五步：获取返回信息

先上一段登录代码：

                HttpItem item = new HttpItem();
                HttpHelper helper = new HttpHelper();
                HttpResult result = new HttpResult();
                item.URL = string.Format("https://passport.jd.com/uc/loginService?uuid={0}&&r={1}&version=2015", _jdLoginer.uuid, _jdLoginer.r);
                item.Method = "post";
                item.Allowautoredirect = true;
                item.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
                item.Postdata = string.Format("uuid={0}&machineNet=&machineCpu=&machineDisk=&eid={1}&fp={2}&{3}={4}"
                    + "&loginname={5}&nloginpwd={6}&loginpwd={6}&chkRememberMe=on&authcode=",
                    _jdLoginer.uuid, _jdLoginer.eid, _jdLoginer.fp, _jdLoginer.tname, _jdLoginer.tvalue, _jdLoginer.loginname,_jdLoginer.loginpwd);
                item.Header.Add("x-requested-with", "XMLHttpRequest");
                item.Header.Add("Accept-Encoding", "gzip, deflate");
                item.Accept = "*/*";
                item.Encoding = Encoding.UTF8;
                item.Cookie = cookies;
                result = helper.GetHtml(item);

                if (!result.Html.Contains("success"))
                {
                    if (result.Html.ToLower().Contains("pwd"))
                    {
                        MessageBox.Show("密码验证不通过!", "系统提示");
                        return;
                    }
                    else if (result.Html.ToLower().Contains("emptyauthcode"))
                    {
                        MessageBox.Show("请输入登录验证码!", "系统提示");
                        return;
                    }
                    else
                    {
                        MessageBox.Show("登陆失败!" + result.Html, "系统提示");
                    }
                }
                else
                {
                    MessageBox.Show("登录京东商城成功！", "系统提示");
                }
