如果没有工作坏证书，当ServerCertificateValidationCallback返回true; 我的ServerCertificateValidationCallback代码:

ServicePointManager.ServerCertificateValidationCallback += delegate
{
    LogWriter.LogInfo("Проверка сертификата отключена, на уровне ServerCertificateValidationCallback");
    return true;
};

我的代码被阻止执行ServerCertificateValidationCallback:

     if (!(ServicePointManager.CertificatePolicy is CertificateValidation))
    {
        CertificateValidation certValidate = new CertificateValidation();
        certValidate.ValidatingError += new CertificateValidation.ValidateCertificateEventHandler(this.OnValidateCertificateError);
        ServicePointManager.CertificatePolicy = certValidate;
    }

OnValidateCertificateError功能:

private void OnValidateCertificateError(object sender, CertificateValidationEventArgs e)
{
    string msg = string.Format(Strings.OnValidateCertificateError, e.Request.RequestUri, e.Certificate.GetName(), e.Problem, new Win32Exception(e.Problem).Message);
    LogWriter.LogError(msg);
    //Message.ShowError(msg);
}

我禁用了CertificateValidation代码和ServerCertificateValidationCallback运行得很好

想法(基于过去的痛苦):

do you have DNS and line-of-sight to the server? are you using the correct name from the certificate? is the certificate still valid? is a badly configured load balancer messing things up? does the new server machine have the clock set correctly (i.e. so that the UTC time is correct [ignore local time, it is largely irrelevent]) - this certainly matters for WCF, so may impact regular SOAP? is there a certificate trust chain issue? if you browse from the server to the soap service, can you get SSL? related to the above - has the certificate been installed to the correct location? (you may need a copy in Trusted Root Certification Authorities) is the server's machine-level proxy set correctly? (which different to the user's proxy); see proxycfg for XP / 2003 (not sure about Vista etc)

我的解(VB。Net，这个应用程序的“登台”(UAT)版本需要与“登台”证书一起工作，但不影响请求一旦他们在现场):

    ...
        Dim url As String = ConfigurationManager.AppSettings("APIURL") & "token"
        If url.ToLower().Contains("staging") Then
           System.Net.ServicePointManager.ServerCertificateValidationCallback = AddressOf AcceptAllCertifications
        End If
    ...

    Private  Function AcceptAllCertifications(ByVal sender As Object, ByVal certification As System.Security.Cryptography.X509Certificates.X509Certificate, ByVal chain As System.Security.Cryptography.X509Certificates.X509Chain, ByVal sslPolicyErrors As System.Net.Security.SslPolicyErrors) As Boolean
        Return True
    End Function

我在Internet Explorer的. net应用程序中遇到了类似的问题。

我解决了将证书(在我的例子中是VeriSign Class 3证书)添加到受信任编辑器证书的问题。

Go to Internet Options-> Content -> Publishers and import it

您可以通过以下方式导出证书:

Internet Options-> Content -> Certificates -> Intermediate Certification Authorities -> VeriSign Class 3 Public Primary Certification Authority - G5

谢谢

我已经用了一段时间了如果有用的话。

调用方必须显式地请求需要不受信任的认证，并在完成时将回调放回默认状态。

    /// <summary>
    /// Helper method for returning the content of an external webpage
    /// </summary>
    /// <param name="url">URL to get</param>
    /// <param name="allowUntrustedCertificates">Flags whether to trust untrusted or self-signed certificates</param>
    /// <returns>HTML of the webpage</returns>
    public static string HttpGet(string url, bool allowUntrustedCertificates = false) {
        var oldCallback = ServicePointManager.ServerCertificateValidationCallback;
        string webPage = "";
        try {
            WebRequest req = WebRequest.Create(url);

            if (allowUntrustedCertificates) {
                // so we can query self-signed certificates
                ServicePointManager.ServerCertificateValidationCallback = 
                    ((sender, certification, chain, sslPolicyErrors) => true);
            }

            WebResponse resp = req.GetResponse();
        
            using (StreamReader sr = new StreamReader(resp.GetResponseStream())) {
                webPage = sr.ReadToEnd().Trim();
                sr.Close();
            }
            return webPage;
        }
        catch {
            // if the remote site fails to response (or we have no connection)
            return null;
        }
        finally {
            ServicePointManager.ServerCertificateValidationCallback = oldCallback;
        }
    }

如果你使用的是Windows 2003，你可以这样做:

Open Microsoft Management Console (Start --> Run --> mmc.exe); Choose File --> Add/Remove Snap-in; In the Standalone tab, choose Add; Choose the Certificates snap-in, and click Add; In the wizard, choose the Computer Account, and then choose Local Computer. Press Finish to end the wizard; Close the Add/Remove Snap-in dialog; Navigate to Certificates (Local Computer) and choose a store to import: If you have the Root CA certificate for the company that issued the certificate, choose Trusted Root Certification Authorities; If you have the certificate for the server itself, choose Other People Right-click the store and choose All Tasks --> Import Follow the wizard and provide the certificate file you have; After that, simply restart IIS and try calling the web service again.
