我做一个登录，登录地址：http://search1.library.sh.cn/mylibrary/html/reader_login.htm，页面的验证码我是先通过IE访问，产生之后写死在代码里，用户名：03000306，用户密码：310225198307296617，
登录的代码如下：

[C#] 纯文本查看 复制代码

 
         /// <summary>
        /// 读者登录
        /// </summary>
        /// <param name="i_reader_no"></param>
        /// <param name="i_body_card"></param>
        /// <returns></returns>
        public ReaderInfo LoginReader(string i_reader_no, string i_body_card)
        {
            string t_login_post_data = string.Format("_language_=zh&login_button.x=45&login_button.y=24user.cardNo={0}&user.identityNo={1}&user.captchacode={2}",
               i_reader_no, i_body_card, "4544");

            HttpItem t_login_item = new HttpItem();
            t_login_item.ContentType = "application/x-www-form-urlencoded";
            t_login_item.URL = AppConfig.SHReaderUrl;
            t_login_item.Postdata = t_login_post_data;
            t_login_item.Method = "POST";
            t_login_item.IsToLower = false;
            t_login_item.ResultType = ResultType.String;

            HttpHelper httpHelper = new HttpHelper();

            try
            {
                HttpResult httpResult = httpHelper.GetHtml(t_login_item);

                string t_cookie = httpResult.Cookie;

                string result = httpResult.Html;

                result = result.Replace("\r", "").Replace("\n", "").Replace("\r\n", "");

                if (result == "String Error")
                    return null;

                return null;

            }
            catch (Exception ex)
            {
                LogHelper.Error("读者登录失败" + ex.ToString());
                return null;
            }
        }

返回的cookie为：JSESSIONID=D373E985E68F8BC7CE5CEF1EE28D75B1; Path=/mylibrary
返回的HTML始终是登录失败的页码代码：

请高手指教下是什么问题，页面的源代码我猜测后台是没做校验的，是前端校验的，因为验证码是JS产生的，没写cookie。

POST前，请求链接，如：http://search1.library.sh.cn/myl ... Code?user.code=3708，
"3708"随便写，请示后获得的Cookie带上POST就成功了。
实测OK。

[C#] 纯文本查看 复制代码

 
               HttpHelper httpHelper = new HttpHelper();

                //请求cookie页
                HttpItem t_login_item = new HttpItem();
                t_login_item.URL = string.Format(AppConfig.SHReaderCookieUrl, "6659");
                HttpResult httpResult = httpHelper.GetHtml(t_login_item);

                string t_login_post_data = string.Format("_language_=zh&login_button.x=45&login_button.y=24user.cardNo={0}&user.identityNo={1}&user.captchacode={2}",
              i_reader_no, i_body_card, "6659");

                //登录
                t_login_item = new HttpItem();
                t_login_item.ContentType = "application/x-www-form-urlencoded";
                t_login_item.URL = AppConfig.SHReaderUrl;
                t_login_item.Postdata = t_login_post_data;
                t_login_item.Method = "POST";
                t_login_item.IsToLower = false;
                t_login_item.ResultType = ResultType.String;

                httpResult = httpHelper.GetHtml(t_login_item);

                string t_cookie = httpResult.Cookie;

                string result = httpResult.Html;

                result = result.Replace("\r", "").Replace("\n", "").Replace("\r\n", "");

                if (result == "String Error")
                    return null;

                return null;

按照你的意思，这样还是不行呢，难道我理解错了？
