这个跟以前的相比使用上并没有多大变化
首先修改一下HttpItem类增加如下代码

string _CerPath = string.Empty;
        /// <summary>
        /// 证书绝对路径
        /// </summary>
        public string CerPath
        {
            get { return _CerPath; }
            set { _CerPath = value; }
        }[/code]
大家看一下验证代码
[code=csharp] #region 验证证书

            if (!string.IsNullOrEmpty(objhttpItem.CerPath))
            {
                //这一句一定要写在创建连接的前面。使用回调的方法进行证书验证。
                ServicePointManager.ServerCertificateValidationCallback =
                    new System.Net.Security.RemoteCertificateValidationCallback(CheckValidationResult);

                //初始化对像，并设置请求的URL地址
                request = (HttpWebRequest)WebRequest.Create(GetUrl(objhttpItem.URL));
                //创建证书文件
                X509Certificate objx509 = new X509Certificate(objhttpItem.CerPath);
                //添加到请求里
                request.ClientCertificates.Add(objx509);
            }
            else
            {
                //初始化对像，并设置请求的URL地址
                request = (HttpWebRequest)WebRequest.Create(GetUrl(objhttpItem.URL));
            }
            #endregion

CheckValidationResult方法如下：

//回调验证证书问题
        public bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
        {
            // 总是接受   
            return true;
        }

例子

这个和以前的使用方法没有多大分别，只是加了一个参数看下面方法

objHttpItem.URL ="https://cckan.net";
            objHttpItem.Encoding = "gb2312";
            objHttpItem.Method = "GET";
            objHttpItem.Referer = "http://cckan.net";
            objHttpItem.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20100101 Firefox/15.0.1";
            objHttpItem.ContentType = "text/html";
            objHttpItem.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
            //objHttpItem.CerPath = "D:\\123.cer";

            //登录cckan.net
            string html = objhttp.GetHtml(objHttpItem);
            //取得登录后的Cookie
            objHttpItem.Cookie = objhttp.cookie;
