C#中实现https的双向认证

1．  把浏览器中的证书导出为cer文件。

2.   代码如下：

1. using System;
2. using System.Net;
3. using System.IO;
4. using System.Security.Cryptography.X509Certificates;
5. using System.Text;
6. using System.Net.Security;
7. public partial class About : System.Web.UI.Page
8. {
9. protected void Page_Load(object sender, EventArgs e)
10. {
11. // string url = "https://192.168.6.120/";
12. ServicePointManager.ServerCertificateValidationCallback = RemoteCertificateValidationCallback;
13. //Uri uri = new Uri("https://www.baifubao.com/");
14. Uri uri = new Uri("https://192.168.6.120/");
15. HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
16. X509Certificate cer = new X509Certificate("F:\\csharp2.cer");
17. request.ClientCertificates.Add(cer);
18. HttpWebResponse response = (HttpWebResponse)request.GetResponse();
19. string encoding = response.ContentEncoding;
20. if (encoding == null || encoding.Length < 1)
21. {
22. encoding = "UTF-8"; //默认编码
23. }
24. StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encoding));
25. Response.Write(reader.ReadToEnd());
26. //Console.Write(reader.ReadToEnd());
27. response.Close();
28. }
29. public static bool RemoteCertificateValidationCallback(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
30. {
31. if (sslPolicyErrors == SslPolicyErrors.None)
32. return true;
33. return false;
34. }
35. }
