Question

说我有两台服务器。一个运行https证书，另一个不运行。访问我的某个网站的用户键入http。如果那些站点使用https证书指向服务器，那么我想重定向用户/重写URL。

只剩下一件事了。如何检查我的网站是否获得了证书？或者如果绑定是https？

void Application_BeginRequest(object sender, EventArgs e)
{
    var path = HttpContext.Current.Request.Url.AbsolutePath;
    var variableToSeeIfIISSiteRunningOnCertificate = true;
    if (variableToSeeIfIISSiteRunningOnCertificate && !HttpContext.Current.Request.IsSecureConnection && !string.IsNullOrEmpty(path) && path.ToLower().Contains("loginpage.aspx"))
    {
        HttpContext.Current.Response.Redirect(HttpContext.Current.Request.Url.AbsoluteUri.Replace("http://", "https://"));
    }
}

using System.Security;
using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates;

public bool HasValidCertificate(url){
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    response.Close();
    X509Certificate cert = request.ServicePoint.Certificate;
    X509Certificate2 cert2 = new X509Certificate2(cert);
    string cn = cert2.GetIssuerName();
    string cedate = cert2.GetExpirationDateString();
    string cpub = cert2.GetPublicKeyString();

    return !string.IsNullOrEmpty(cn) && cedate > DateTime.Now && !string.IsNullOrEmpty(cpub);
}

没有经过测试，但应该对如何做到这一点有所了解。
