C#、VB.NET使用HttpWebRequest访问https地址(SSL)的实现方法

view sourceprint?using System.Net;

using System.Net.Security;

using System.Security.Authentication;

using System.Security.Cryptography.X509Certificates;

.Net 1.1

view sourceprint?01 internal class AcceptAllCertificatePolicy : ICertificatePolicy

{

public AcceptAllCertificatePolicy()

{

}

public bool CheckValidationResult(ServicePoint sPoint, System.Security.Cryptography.X509Certificates.X509Certificate cert, WebRequest wRequest, int certProb)

{

//直接确认

return true;

}

}

private void button1_Click(object sender, EventArgs e)

{

ServicePointManager.CertificatePolicy = new AcceptAllCertificatePolicy();

HttpWebRequest req = (HttpWebRequest)WebRequest.CreateDefault(new Uri("https://XXXX"));

req.Method = "GET";

HttpWebResponse res = (HttpWebResponse)req.GetResponse();

//...正常使用了，和访问普通的 http:// 地址一样了

}

.Net 2.0

view sourceprint?01 public bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)

{

//直接确认，否则打不开

return true;

}

private void button1_Click(object sender, EventArgs e)

{

ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(CheckValidationResult);

HttpWebRequest req = (HttpWebRequest)WebRequest.CreateDefault(new Uri("https://XXXX"));

req.Method = "GET";

HttpWebResponse res = (HttpWebResponse)req.GetResponse();

//...正常使用了，和访问普通的 http:// 地址一样了

}
