自动登录一直提示验证码错误

ofaith

用万能框架dll写一个网站自动登录的软件，一直提示验证码错误，流程如下：1、先获取验证码和cookie；2、用cookie提交登录。
获取验证码的代码如下：

[C#] 纯文本查看 复制代码

            Shanqiu sq = new Shanqiu();
            HttpHelper http = new HttpHelper();
            HttpItem item = new HttpItem()
            {
                URL = "https://xxxxx.com/code?_=" + sq.GetTimeStampMsOF(),
                Method = "GET",
            };
            Image img = http.GetImage(item);
            pictureBox1.Image = img;
            HttpResult result = http.GetHtml(item);
            myCookie = result.Cookie;

sq.GetTimeStampMsOF是我自己写的一个类，主要用来获取时间戳

登录的代码如下：

[C#] 纯文本查看 复制代码

            string u = txtUsername.Text.Trim();
            string p = txtPassword.Text.Trim();
            string v = txtValidate.Text.Trim();
            string data = "type=1&account=" + u + "&password=" + p + "&code=" + v;
            
            HttpHelper http = new HttpHelper();
            HttpItem item = new HttpItem()
            {
                URL = "https://xxxx.com/login",
                Method = "POST",
                ContentType = "application/x-www-form-urlencoded",
                PostEncoding = Encoding.UTF8,
                Postdata = data,
                Referer = "https://xxxx.com/login",
                Cookie = myCookie,
            };
            Console.WriteLine(Encoding.UTF8);
            HttpResult result = http.GetHtml(item);
            string cookie = result.Cookie;
            Console.WriteLine(result.Header);

myCookie是全局变量，用来存储获取验证码时的cookie。

因为隐私问题我把URL用XXXX.com来代替。
返回的头信息显示验证码错误，请问各位大神知道是哪里出错吗？

搞定了，感谢总群的Sunshine网友帮忙！给个小红包感谢！

[C#] 纯文本查看 复制代码

Image img = http.GetImage(item);
pictureBox1.Image = img;
HttpResult result = http.GetHtml(item);
myCookie = result.Cookie;

这段代码的问题，这里发送了两个验证码请求，导致验证码和cookie不一致。
正确代码如下：

[C#] 纯文本查看 复制代码

HttpResult result = http.GetHtml(item);
Image img = byteArrayToImage(result.ResultByte);
pictureBox1.Image = img;
myCookie = result.Cookie;
