我在从 WCF 客户端连接到第三方 WSE 3.0 Web 服务时遇到困难。我已经实现了此知识库文章中所示的自定义绑定(bind)类:
http://msdn.microsoft.com/en-us/library/ms734745.aspx
问题似乎与 Web 服务使用的安全断言 - UsernameOverTransport 有关。
当我尝试调用方法时,出现以下异常:
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 号码。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();
<小时/>
这在安装了 WSE 3.0 的 2.0 应用程序中运行良好。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
我在网上搜索了这个问题的答案。有些来源让我很接近(例如 MS 知识库文章),但我似乎无法克服困难。有人可以帮我吗?
最佳答案
我使用以下绑定(bind)配置在类似的案例中取得了成功:
<bindings>
<customBinding>
<binding name="FNCEWS40MTOMBinding">
<security enableUnsecuredResponse="true" authenticationMode="UserNameOverTransport"
allowInsecureTransport="true" messageProtectionOrder="SignBeforeEncrypt">
<secureConversationBootstrap />
</security>
<mtomMessageEncoding messageVersion="Soap12WSAddressingAugust2004"
maxBufferSize="2147483647" />
<httpTransport maxReceivedMessageSize="2147483647" />
</binding>
</customBinding>
</bindings>
希望它也适合您。
