人生从来没有真正的绝境。无论遭受多少艰辛，无论经历多少苦难，只要一个人的心中还怀着一粒信念的种子，那么总有一天，他就能走出困境，让生命重新开花结果。

我的获取页面需要cookie，不需要的可以去掉；

GET的方法：


/// <summary>
 /// 获取URL访问的HTML内容 获取https 页面的
 /// </summary>
 /// <param name="Url">URL地址</param>
 /// <returns>HTML内容</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：


/// <summary>
 /// post提交数据到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;
 //提交请求
 Stream stream;
 stream = request.GetRequestStream();
 stream.Write(postdatabyte, 0, postdatabyte.Length);
 stream.Close();
 //接收响应
 response = (HttpWebResponse)request.GetResponse();
 using (StreamReader reader = new StreamReader(response.GetResponseStream()))
 {
 restr = reader.ReadToEnd().ToString();
 }
 return restr;
 }
