该问题似乎与Web服务使用的安全断言有关 – UsernameOverTransport.

当我尝试调用方法时,我得到以下异常：

System.InvalidOperationException: The
‘WseHttpBinding’.'[namespace]’
binding for the
‘MyWebServiceSoap’.'[namespace]’
contract is configured with an
authentication mode that requires
transport level integrity and
confidentiality. However the transport
cannot provide integrity and
confidentiality..

它需要用户名,密码和CN号.在供应商提供给我们的示例代码中,这些凭据捆绑在Microsoft.Web.Services3.Security.Tokens.UsernameToken中.以下是供应商提供的示例：

MyWebServiceWse proxy = new MyWebServiceWse();

UsernameToken token = new UsernameToken("Username","password",PasswordOption.SendPlainText);

token.Id = "<supplied CN Number>";

proxy.SetClientCredential(token);

proxy.SetPolicy(new Policy(new UsernameOverTransportAssertion(),new RequireActionHeaderAssertion()));

MyObject mo = proxy.MyMethod();

这适用于安装了WSE 3.0的2.0应用程序.以下是我的WCF客户端的代码片段：

EndpointAddress address = new EndpointAddress(new Uri("<web service uri here>"));

WseHttpBinding binding = new WseHttpBinding(); // This is the custom binding I created per the MS KB article

binding.SecurityAssertion = WseSecurityAssertion.UsernameOverTransport;
binding.EstablishSecurityContext = false;

// Not sure about the value of either of these next two
binding.requirederivedKeys = true;
binding.MessageProtectionOrder = MessageProtectionOrder.SignBeforeEncrypt;

MembershipServiceSoapClient proxy = new MembershipServiceSoapClient(binding,address);

// This is where I believe the problem lies – I can’t seem to properly setup the security credentials the web service is expecting 

proxy.ClientCredentials.UserName.UserName = "username";
proxy.ClientCredentials.UserName.Password = "pwd";
// How do I supply the CN number?                      

MyObject mo = proxy.MyMethod(); // this throws the exception

我在网上搜索这个问题的答案.一些消息来源让我接近(如MS KB文章),但我似乎无法克服困难.有人可以帮我吗？
