HTTPs客户端连接到Azure Web App上没有受信任链(非受信任CA)的服务器

我已经被困了大约3天试图连接到一个没有被可信任CA签名的证书的服务器 - 你可以通过Azure门户添加CA的证书 - 但是没有影响。

显然,所有HTTP都使用内核模块(!)HTTP.SYS。

我所看到的所有建议都要使用:

ServicePointManager.ServerCertificateValidationCallback = Communicator.CustomServiceCertificateValidation;

(或其在请求本身上的不那么全球性的对应物)

或类似的东西:

 client.ClientCredentials.ServiceCertificate.SslCertificateAuthentication =
                 new X509ServiceCertificateAuthentication()
                 {
                     CertificateValidationMode = X509CertificateValidationMode.Custom,
                     RevocationMode = X509RevocationMode.NoCheck,

                     //TrustedStoreLocation = StoreLocation.CurrentUser,
                     CustomCertificateValidator = new PermissiveCertificateValidator()

                 };

然而,两者都没有被调用!!

一些更重要的细节:

这有效:

  try
        {
            ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
            using (var wc = new WebClient())
            {
                var res = wc.DownloadString("https://untrusted-root.badssl.com/");
                return Content(res);
            }
        }
        catch (Exception ex)
        {
            return Content(ex.ToString());
        }

然而,我需要使用客户端证书对自己进行身份验证 - 因此,请按照此处的说明进行操作: How can you add a Certificate to WebClient (C#)?

我最终得到以下代码:

class ATWebClient : WebClient
{
    protected override WebRequest GetWebRequest(Uri address)
    {
        HttpWebRequest request = (HttpWebRequest)base.GetWebRequest(address);
        request.Headers.Add("SOAPAction", "https://servicos.portaldasfinancas.gov.pt/sgdtws/documentosTransporte/");
        X509Certificate2 cert = new X509Certificate2();
        //From user installed Certificates
        //cert.Import(_pathCertificate, _passwordCertificate, X509KeyStorageFlags.DefaultKeySet);
        //From FileSystem "Resources\Certificates"
        cert.Import(Common.Properties.Resources.testewebservices_novo, "TESTEwebservice", X509KeyStorageFlags.Exportable);

        // Output Certificate 
        //Utils.Log(string.Format("Cert Subject: [{0}], NotBefore: [{1}], NotAfter: [{2}]", cert.Subject, cert.NotBefore, cert.NotAfter));

        request.ClientCertificates.Add(cert);
        request.Method = "POST";
        request.ContentType = "text/xml; charset=utf-8";
        request.Accept = "text/xml";


        return request;
    }

现在我用:

调用服务
   try
    {

        ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
        ServicePointManager.CheckCertificateRevocationList = false;
        ServicePointManager.UseNagleAlgorithm = false;
        using (var wc = new ATWebClient())
        {
            //var res = wc.DownloadString("https://servicos.portaldasfinancas.gov.pt:701/sgdtws/documentosTransporte");
            var res = wc.UploadString("https://servicos.portaldasfinancas.gov.pt:701/sgdtws/documentosTransporte", "Test of content");
            return Content(res);
        }


    }
    catch (Exception ex)
    {
        return Json(ex);
    }

注意,是的,这是一个SOAP端点 - 我尝试发送有效的SOAP内容,但结果在两种情况下都相同,我得到以下异常:

The underlying connection was closed: An unexpected error occurred on a send.

堆栈跟踪:

内部异常消息:

Authentication failed because the remote party has closed the transport stream.

任何想法?! HALP!

硬编码如何在您的自定义回调中返回true?

set: (target, prop, value) => {
  if(!isNaN(prop) && Number(prop) >= length){
    return false;
  }

  if (Number(prop) < length) {
    target[prop] = value;
  }

  return true;
}
