SSIS SecurityNegotiationException：无法为 SSL/TLS 建立安全通道（无证书）

Question

我正在通过 SSIS 与网络服务集成。我不断收到似乎是无法与证书通信的错误。

当我运行在控制台中使用完全相同的代码时，它工作正常。

该服务不需要证书，这是 SSIS 的东西吗？我是 SSIS 的新手，所以这可能是一个基本问题。

异常：

System.ServiceModel.Security.SecurityNegotiationException: Could not establish secure channel for SSL/TLS with authority 'myurl'. --->

System.Net.WebException：请求被中止：无法创建 SSL/TLS 安全通道

代码如下：

    var wsBinding = new WSHttpBinding(SecurityMode.Transport);
    wsBinding.Name = "wsHttpBinding_GlobalCredentials";
    wsBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;

    
    System.Net.ServicePointManager.ServerCertificateValidationCallback += delegate { return true; };

    EndpointAddress endpointAddress = new EndpointAddress("https://myurl/myservice.svc/Soap12_NoAuth");


    using (GlobalCredentialsClient globalCredentialsClient = new GlobalCredentialsClient(wsBinding, endpointAddress))
    {
        try
        {
            globalCredentialsClient.ChannelFactory.Credentials.ServiceCertificate.SslCertificateAuthentication = new X509ServiceCertificateAuthentication();                    
            globalCredentialsClient.ChannelFactory.Credentials.ServiceCertificate.SslCertificateAuthentication.CertificateValidationMode = X509CertificateValidationMode.None;

            
            GlobalAccount checkCredentialsResult = globalCredentialsClient.CheckCredentials(username, password);

            MessageBox.Show("Result: " + checkCredentialsResult.OrgID.ToString());

            Dts.Variables["sOrgName"].Value = checkCredentialsResult.Created;

            globalCredentialsClient.Close();
        }
        catch (CommunicationException ce)
        {
            MessageBox.Show("Comms exc " + ce.ToString());
            globalCredentialsClient.Abort();

        }
    }

预感，可能是 TLS 版本不匹配。失败的应用程序是哪个 .NET？

您可以尝试在 API 调用之前设置 TLS 版本。

System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12

或

System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls11
