.net 获取https页面的信息 在iis7.5服务器上不管用

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         }
