WebRequest 访问 https

参考代码：

   1:         [TestMethod]

   2:          public void TestHttps()

   3:          {

   4:              var req =(HttpWebRequest) System.Net.WebRequest.Create("https://www.baidu.com/");

   5:              ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

   6:              var rep =(HttpWebResponse) req.GetResponse();

   7:              var stream = rep.GetResponseStream();

   8:              StreamReader reader = new StreamReader(stream);

   9:              string content = reader.ReadToEnd();

  10:              reader.Close();

  11:              stream.Close();

  12:          }

关键代码：ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
