当我尝试导出元数据时，我收到错误。我的绑定代码是
HttpTransportBindingElement httpTransport = new HttpTransportBindingElement();
// the transport security binding element will be configured to require a username token
TransportSecurityBindingElement transportSecurity = new TransportSecurityBindingElement();
transportSecurity.EndpointSupportingTokenParameters.Signed.Add(new UsernameTokenParameters());
//transportSecurity.ProtectTokens = true;
// transportSecurity.ProtectTokens = true;
// transportSecurity.EndpointSupportingTokenParameters.SignedEncrypted.Add(new UsernameTokenParameters());
transportSecurity.MessageSecurityVersion = MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10;
transportSecurity.IncludeTimestamp = true;
//transportSecurity.MessageProtectionOrder = System.ServiceModel.Security.MessageProtectionOrder.EncryptBeforeSign;
// here you can require secure transport, in which case you'd probably replace HTTP with HTTPS as well
transportSecurity.AllowInsecureTransport = true;
//transportSecurity.IncludeTimestamp = false;
TextMessageEncodingBindingElement me = new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8);
return new CustomBinding(transportSecurity, httpTransport);
以下是错误和跟踪。请帮助...
