解決iis7.5服務(wù)器上.net 獲取不到https頁面的信息

更新時間：2014年06月09日 14:26:55 作者：

讓我糾結(jié)了一天多的問題，給大家看下，有相同情況的可以不用浪費時間了，本人當(dāng)時找了好半天都沒找到什么有用的信息，項目在本地沒有問題，但部署在服務(wù)器后，獲取不到https頁面的信息，加入下面的代碼就可以了，因為iis7.5的安全協(xié)議比較高的原因。

我的獲取頁面需要cookie，不需要的可以去掉；

GET的方法：

復(fù)制代碼代碼如下:

/// <summary>
        /// 獲取URL訪問的HTML內(nèi)容獲取https 頁面的
        /// </summary>
        /// <param name="Url">URL地址</param>
        /// <returns>HTML內(nèi)容</returns>
        public static string GetWebContent(string Url, CookieContainer cookieContainer)
        {
            string strResult = "";
            try
            {
                ServicePointManager.Expect100Continue = true;
                ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);
                request.CookieContainer = cookieContainer;
                request.Timeout = 30000;
                request.Headers.Set("Pragma", "no-cache");

HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream streamReceive = response.GetResponseStream();

                Encoding encoding = Encoding.GetEncoding("utf-8");
                StreamReader streamReader = new StreamReader(streamReceive, encoding);
                strResult = streamReader.ReadToEnd();
            }
            catch
            {

            }
            return strResult;
        }

POST的方法：

復(fù)制代碼代碼如下:

/// <summary>
        /// post提交數(shù)據(jù)到https
        /// </summary>
        /// <param name="posturl"></param>
        /// <param name="postdata"></param>
        /// <param name="header"></param>
        /// <param name="cookieContainer"></param>
        /// <returns></returns>
        public static string SetPostHtml(string posturl, string postdata, HttpHeader header, CookieContainer cookieContainer)
        {
            string restr = "";
            ServicePointManager.Expect100Continue = true;
            ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
            HttpWebRequest request = null;
            HttpWebResponse response = null;
            request = (HttpWebRequest)WebRequest.Create(posturl);
            request.CookieContainer = cookieContainer;
            request.Method = header.method;
            request.Referer = header.Referer;
            request.ContentType = header.contentType;
            byte[] postdatabyte = Encoding.UTF8.GetBytes(postdata);
            request.ContentLength = postdatabyte.Length;
            request.AllowAutoRedirect = false;
            request.KeepAlive = true;
            //提交請求
            Stream stream;
            stream = request.GetRequestStream();
            stream.Write(postdatabyte, 0, postdatabyte.Length);
            stream.Close();
            //接收響應(yīng)
            response = (HttpWebResponse)request.GetResponse();
            using (StreamReader reader = new StreamReader(response.GetResponseStream()))
            {
                restr = reader.ReadToEnd().ToString();
            }
            return restr;
        }
