望苏飞大哥给指定下。

[C#] 纯文本查看 复制代码

HttpItem item = new HttpItem()
            {
                KeepAlive = false,
                Accept = "image/jpeg, application/x-ms-application, image/gif, application/xaml+xml, image/pjpeg, application/x-ms-xbap, */*",
                UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0)",
                ProtocolVersion = HttpVersion.Version10,
                Host = "upay.10010.com",
                Referer = "https://upay.10010.com/web/Buycard/BuycardInit?MediaCardAmount=1&MediaCardCode=01&&menuId=000200030001",
                Method = "POST",
                PostDataType = Utilities.PostDataType.Byte,
                PostdataByte = Encoding.UTF8.GetBytes(postData),
                //Postdata = string.Format(postData, cardNum, State, verifyCode),
                URL = url,//URL必需项
                ResultCookieType = Utilities.ResultCookieType.CookieCollection,
                CookieCollection = UnicomCookie,
                //Encoding = null,//编码格式（utf-8,gb2312,gbk）可选项 默认类会自动识别
                Encoding = UTF8Encoding.UTF8,
                ResultType = ResultType.String,
                ContentType = "application/x-www-form-urlencoded"
            };

POST的数据我也和Fiddler2抓包后的数据对比了下，没有什么问题啊。result.StatusCode也是OK，就是取回来的页面不是我想要的界面说我验证码错误，实际上验证码数据的没有错误的。

站长苏飞

有验证码是肯定 要带Cookie的，流程是先获取登录的Cookie，带Cookie去请求验证码，然后带cookie去Post
