WCF wsdualhttpBinding自定义用户名

我有一个非常烦人的错误: 我的场景 - 在WCF中使用wsdualhttpbinding实现的简单消息/邮件服务器\客户端(对于回调而言是双重的,对新消息进行在线更新)。

所有安全配置都是用代码编写的(根本没有* .config)。首次连接时,客户端会抛出以下内容 [System.Security.Cryptography.CryptographicException] = {“Bad Length。\ r \ n”} 具有NULL内部异常,因此无法钻取更深的内容。 服务器配置:

     WSDualHttpBinding binding = new   WSDualHttpBinding(WSDualHttpSecurityMode.Message);
    binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;

        Uri baseServiceAddress = new Uri(@"http://"+Environment.MachineName+":7921/Mail/");                 
        host = new ServiceHost(theMightyMailServer,baseServiceAddress);             

        host.Credentials.ClientCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None;
        host.Credentials.UserNameAuthentication.UserNamePasswordValidationMode = UserNamePasswordValidationMode.Custom;
        host.Credentials.UserNameAuthentication.CustomUserNamePasswordValidator = validator;
        host.Credentials.ServiceCertificate.SetCertificate(StoreLocation.CurrentUser, StoreName.Root, X509FindType.FindByIssuerName, "MailServer");
        ServiceDebugBehavior d = new ServiceDebugBehavior();
        d.IncludeExceptionDetailInFaults = true;
        host.Description.Behaviors.Remove<ServiceDebugBehavior>();
        host.Description.Behaviors.Add(d);
        ServiceMetadataBehavior b = new ServiceMetadataBehavior();
        b.HttpGetEnabled = true;
        host.Description.Behaviors.Remove<ServiceMetadataBehavior>();
        host.Description.Behaviors.Add(b);
        var mexBinding = MetadataExchangeBindings.CreateMexHttpBinding();
        host.AddServiceEndpoint(typeof(IMailServer), binding, "Service");
        host.AddServiceEndpoint(typeof(IMetadataExchange),mexBinding,"");


        host.Open();

客户端配置:

           client = new MailServerReference.MailServerClient(new InstanceContext(this));

            client.ClientCredentials.UserName.UserName = currentUser.UserName;
            client.ClientCredentials.UserName.Password = currentUser.Password;
                client.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.None;
            client.ClientCredentials.ClientCertificate.SetCertificate(StoreLocation.CurrentUser, StoreName.Root,X509FindType.FindByIssuerName, "MailServer");
            currentUser.ID = client.getUID();
            client.RegisterOnServer(currentUser.ID);
            return true;

        }
        catch (Exception ex) { MessageBox.Show(ex.Message); return false; }

任何帮助都会非常感激。而BTW我是WCF的新手,所以也许我错过了一些基本的概念。

答案 0 :(得分:0)

我会尝试在客户端和服务器上将ServiceCertificateClientCertificate设置为相同的内容。至少,这就是我做到这一点的方式。它已经有一段时间了,但我认为只有一个证书或另一个证书才有问题,而不是两者都有。


编辑以获取更多信息:

在我的情况下,我使用的是CustomBinding而不是WSDualHttpBinding,但我最终在两端(客户端和服务器)使用完全相同的ServiceCertificate和ClientCertificate证书。

更具体地说,我有一个扩展System.ServiceModel.Description.ServiceCredentials

的类
public class MyServiceCredentials : ServiceCredentials
{
    public MyServiceCredentials() : base()
    {
        LoadCertificate();
    }

    public MyServiceCredentials(MyServiceCredentials other) : base(other)
    {
        LoadCertificate();
    }

    private void LoadCertificate()
    {
        ServiceCertificate.Certificate = _cert;
        ClientCertificate.Certificate = _cert;
        ClientCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None;
        ClientCertificate.Authentication.RevocationMode = X509RevocationMode.NoCheck;
   }
}

我在客户端和服务器实现中将其中一个传递给我的CustomBinding构造函数。

无论如何,我认为因为绑定启用了Message安全性,它期望在两个方向都有消息级安全性,因此它需要双方的证书(ServiceCertificate和ClientCertificate)。

我可能完全错了,我只是说;尝试一下,看看是否有帮助...
