本文介绍了一种在.NET 1.1和.NET 2.0中绕过HTTPS证书验证的方法，通过自定义证书策略实现对任何HTTPS地址的无限制访问。

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 }
