原文:.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 }
希望对大家有帮助；
