标题: 我今天用httphelper结合webBrowser1测试一下在优酷留言的功能，发现留不了
我的思路是这样的：
1、用webBrowser1登录到优酷访客空间上去
2、用GetCookies获取webBrowser1登录的cookies
3、直接用HttpHelper 向优酷的URL留言：http://i.youku.com/u/UMzE3MDIzMz ... ge?__rt=1&__ro=
HttpHelper http = new HttpHelper();
            //创建Httphelper参数对象
HttpItem item = new HttpItem()
{
      URL = webBrowser1.Url.ToString() + @"/guestbook/fun_message?__rt=1&__ro=",//URL    必需项
      Method = "post",//URL    可选项默认为Get
      ContentType = "application/x-www-form-urlencoded; charset=UTF-8",//返回类型可选项有默认值
      Postdata = "to_user_id=" + userid + "&sync_renren=0&sync_sina=0&sync_tencent=0&sync_messenger=0&sync_qzone=0&sync_kaixin=0&text=" + Uri.EscapeDataString(richTextBox2.Lines[xx].ToString()),//Post要发送的数据
      Cookie = GetCookies(webBrowser1.Url.ToString()),
};

[DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)]
      static extern bool InternetGetCookieEx(string pchURL, string pchCookieName, StringBuilder pchCookieData, ref System.UInt32 pcchCookieData, int dwFlags, IntPtr lpReserved);
      [DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)]
      static extern int InternetSetCookieEx(string lpszURL, string lpszCookieName, string lpszCookieData, int dwFlags, IntPtr dwReserved);
      #region 获取cookies
      private static string GetCookies(string url)
      {
         uint datasize = 256;
         StringBuilder cookieData = new StringBuilder((int)datasize);
         if (!InternetGetCookieEx(url, null, cookieData, ref datasize, 0x2000, IntPtr.Zero))
         {
            if (datasize < 0)
                  return null;

            cookieData = new StringBuilder((int)datasize);
            if (!InternetGetCookieEx(url, null, cookieData, ref datasize, 0x00002000, IntPtr.Zero))
                  return null;
         }
         return cookieData.ToString();
      }
      #endregion
我通过这个测试之后，发现怎么也留不了言！我确定已经提交过了，总是提示：{"en":"ERR_USER_OVERPOST_TWEET","zh":"\u60a8\u63d0\u4ea4\u7684\u901f\u5ea6\u592a\u5feb\u4e86\uff0c\u8bf7\u7a0d\u5019\u53d1\u8868\uff01","captcha_expire":21000}
我用F，I，d，dlER4都都无法获取到这个框架发送的数据呢
