.net 获取https页面的信息在iis7.5服务器上不管用

让我纠结了一天多的问题，给大家看下，有相同情况的可以不用浪费时间了，本人当时找了好半天都没找到什么有用的信息，项目在本地没有问题，但部署在服务器后，获取不到https页面的信息，加入下面的代码就可以了，因为iis7.5的安全协议比较高的原因。

我的获取页面需要cookie，不需要的可以去掉；

GET的方法：

 1  /// <summary>
 2         /// 获取URL访问的HTML内容 获取https 页面的
 3         /// </summary>
 4         /// <param name="Url">URL地址</param>
 5         /// <returns>HTML内容</returns>
 6         public static string GetWebContent(string Url, CookieContainer cookieContainer)
 7         {
 8             string strResult = "";
 9             try
10             {
11                 ServicePointManager.Expect100Continue = true;
12                 ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
13                 HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);
14                 request.CookieContainer = cookieContainer;
15                 request.Timeout = 30000;
16                 request.Headers.Set("Pragma", "no-cache");
17 
18                 HttpWebResponse response = (HttpWebResponse)request.GetResponse();
19                 Stream streamReceive = response.GetResponseStream();
20 
21                 Encoding encoding = Encoding.GetEncoding("utf-8");
22                 StreamReader streamReader = new StreamReader(streamReceive, encoding);
23                 strResult = streamReader.ReadToEnd();
24             }
25             catch
26             {
27 
28             }
29             return strResult;
30         }

POST的方法：

 1 /// <summary>
 2         /// post提交数据到https
 3         /// </summary>
 4         /// <param name="posturl"></param>
 5         /// <param name="postdata"></param>
 6         /// <param name="header"></param>
 7         /// <param name="cookieContainer"></param>
 8         /// <returns></returns>
 9         public static string SetPostHtml(string posturl, string postdata, HttpHeader header, CookieContainer cookieContainer)
10         {
11             string restr = "";
12             ServicePointManager.Expect100Continue = true;
13             ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
14             HttpWebRequest request = null;
15             HttpWebResponse response = null;
16             request = (HttpWebRequest)WebRequest.Create(posturl);
17             request.CookieContainer = cookieContainer;
18             request.Method = header.method;
19             request.Referer = header.Referer;
20             request.ContentType = header.contentType;
21             byte[] postdatabyte = Encoding.UTF8.GetBytes(postdata);
22             request.ContentLength = postdatabyte.Length;
23             request.AllowAutoRedirect = false;
24             request.KeepAlive = true;
25             //提交请求
26             Stream stream;
27             stream = request.GetRequestStream();
28             stream.Write(postdatabyte, 0, postdatabyte.Length);
29             stream.Close();
30             //接收响应
31             response = (HttpWebResponse)request.GetResponse();
32             using (StreamReader reader = new StreamReader(response.GetResponseStream()))
33             {
34                 restr = reader.ReadToEnd().ToString();
35             }
36             return restr;
37         }
