I have written a one-way service in php that contains one method with OperationContract( IsOneWay=true)
When I call this method from my .net client application then it gives me an error
The one-way operation returned a
non-null message with Action=''
Here is my proxy generated method :
[OperationContractAttribute(IsOneWay = true, Action = "http://192.168.1.5/zfsapi/api.php#terminateProcess")]
[XmlSerializerFormatAttribute(Style=OperationFormatStyle.Rpc, SupportFaults=true, Use=OperationFormatUse.Encoded)]
[ServiceKnownTypeAttribute(typeof(ZfsSnapshot))]
void terminateProcess(int pid);
Can anyone tell me why this error occur and solution on this?

I'm currently handing off exceptions to a third party telemetry tracking service (Raygun). One of the details I want to include in those exception logs is the actual contents of the message, ideally serialized to JSON.
I'm handling this at the end of the MessageHandler. I'm aware that I could also use the IManageMessageFailures interface, but then I lose the benefits of the second level retries.
I'm currently doing this:
public void End(Exception e)
{
// get the current message context
var context = this.Bus.CurrentMessageContext;
// now where do I get the body of the message from?
this.ExceptionLogger(new Log(e, context.WhereAreYouMessage.SerializedAsString()));
}
This is NSB 3.3. I notice that I can cast the CurrentMessageContext to NServiceBus.Unicast.MessageContext, but the TransportMessage property which contains the message Body is private.
How can I get a copy of the message that caused the exception?
This is not supported in version 3.
You can look in your error queue which will have the exception details correlated with the message body http://docs.particular.net/nservicebus/errors/#configure-your-error-queue
I'm trying the built-in Authentication of ServiceStack. My approach is 'OrmLiteAuthRepository' so users' information are stored in Sql Server instead of the default in memory storage. I use Postman to test the endpoints.
My target is receiving user rows, updating user information, creating users, deleting an user row. Those are the endpoints I found in Postman after importing (I didn't create those endpoints):
GET 'http://localhost:47391/api/register',
PUT 'http://localhost:47391/api/json/reply/Register'
POST 'http://localhost:47391/api/json/reply/Register'
I tested POST, Sql Server automatically created the tables to store user data. And the data could be written into Sql Server so I have no problem with POST.
But with PUT, isn't it for updating the existing row? I append '/{id}' to the end. But it created a new row in the database instead of updating the existing one. How does it work?
With GET, I got no implementation error.

How to implement it? I assume I consider the user a normal Web Service entity? and create 'UserService', and requests like:
[Route("/register")]
public class User : IReturn<UserResponse>
{
...
}
BUT there isn't a model class like 'User' due to the tables are created by ServiceStack itself, how to solve this?
Or is there something I am not aware of. Thanks.
The error message:
Could not find method named Get(Register) or Any(Register) on Service RegisterService
Is saying you're trying to call the built-in ServiceStack Register Service instead of your Service. But the Register Services isn't enabled by default, your AuthFeature likely explicitly enables it, either with:
Plugins.Add(new RegistrationFeature());
Or on the AuthFeature:
Plugins.Add(new AuthFeature(...) {
IncludeRegistrationService = true
});
If you don't want to enable ServiceStack's built-in Register Service you'll need to remove the registration where it's enabled.
If you instead want the Register Service registered at a different path, you can specify a different route with:
Plugins.Add(new RegistrationFeature {
AtRestPath = "/servicestack-register"
});
I'm writing a client against a vendor's webservice, using WCF in Visual Studio 2010. I have no ability to change their implementation or configuration.
Running against an install on their test server, I had no problems. I added a service reference from their wsdl, set the url in code, and made the call:
var client = new TheirWebservicePortTypeClient();
client.Endpoint.Address = new System.ServiceModel.EndpointAddress(webServiceUrl);
if (webServiceUsername != "")
{
client.ClientCredentials.UserName.UserName = webServiceUsername;
client.ClientCredentials.UserName.Password = webServicePassword;
}
TheirWebserviceResponse response = client.TheirOperation(myRequest);
Simple and straightforward. Until they moved it to their production server and configured it to use https. Then I got this error:
The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Basic realm='.
So I went looking for help. I found this: Can not call web service with basic authentication using wcf.
The approved answer suggested this:
BasicHttpBinding binding = new BasicHttpBinding();
binding.SendTimeout = TimeSpan.FromSeconds(25);
binding.Security.Mode = BasicHttpSecurityMode.Transport;
binding.Security.Transport.ClientCredentialType =
HttpClientCredentialType.Basic;
EndpointAddress address = new EndpointAddress(your-url-here);
ChannelFactory<MyService> factory =
new ChannelFactory<MyService>(binding, address);
MyService proxy = factory.CreateChannel();
proxy.ClientCredentials.UserName.UserName = "username";
proxy.ClientCredentials.UserName.Password = "password";
Which also seemed simple enough. Except for my trying to figure out which of the multitude of classes and interfaces that were generated from the wsdl to make the service reference I should use in place of the "MyService", above.
My first try was to use "TheirWebservicePortTypeClient" - the class I had instantiated in the previous version. That gave me a runtime error:
The type argument passed to the generic ChannelFactory class must be an interface type.
So I dug into the generated code, a bit more. I saw this:
public partial class TheirWebservicePortTypeClient
:
System.ServiceModel.ClientBase<TheirWebservicePortType>,
TheirWebservicePortType
{
...
}
So I tried instantiating ChannelFactory<> with TheirWebservicePortType.
This gave me compile-time errors. The resulting proxy didn't have a ClientCredentials member, or a TheirOperation() method.
So I tried "System.ServiceModel.ClientBase".
Instantiation ChannelFactory<> with it still gave me compile-time errors. The resulting proxy did have a ClientCredentials member, but it still didn't have a TheirOperation() method.
So, what gives? How do I pass a username/password to an HTTPS webservice, from a WCF client?
==================== Edited to explain the solution ====================
First, as suggested, instantiation the factory with TheirWebservicePortType, adding the username and password to the factory.Credentials, instead of to proxy.ClientCredentials worked fine. Except for one bit of confusion.
Maybe it's something to do with the odd way the wsdl is written, but the client class, TheirWebservicePortTypeClient, defined TheirOperation as taking a Request argument and returning a Response result. The TheirWebservicePortType interface defined TheirOperation as taking a TheirOperation_Input argument and returning a TheirOperation_Output result, where TheirOperation_Input contained a Request member and TheirOperation_Output contained a Response member.
In any case, if I constructed a TheirOperation_Input object from the passed Request, the call to the proxy succeeded, and I could then extract the contained Response object from the returned TheirOperation_Output object:
TheirOperation_Output output = client.TheirOperation(new TheirOperation_Input(request));
TheirWebserviceResponse response = output.TheirWebserviceResponse;
You add the credentials to the ChannelFactory Credentials property
I have web services written on WCF. I use request/response pattern and don't use FaultException. I return an error code in response contract as string. I need to expose error codes for clients in order to clients can handle exceptions.
For example:
Var r = client.DoSomething();
Switch (r.ErrorCode)
{
Case ERROR_CODES.SomeCode:
//TODO:
}
Clients are WS-*, not only .Net.
UPDATE:
Sorry, my English is elementary. I've tried to explain in a different way.
When I use class File, I know that this class can throws some exceptions, for example, FileNotFoundException or DirectoryNotFoundException. If I create a File service How can I tell client that my service can returns "FileNotFound" or other error codes?
We generally try and use FaultContracts.
When we cannot we use a Response object that inherits from ResponseBase. ResponseBase has 2 properties, StatusCode and StatusMessage.
In your case ErrorCode, just add this property to your data contract.
I'm logging using log4net, and I want to log a id that is unique for each serice method call. I dont need it unique across service calls, just within a method call. Is there any built in id i can use in wcf? I don't want to manually create a guid or something at the start of the method call.
e.g.
wcfMethod(int x)
{
log("xxx");
somework
log("yyy");
}
private log(string message)
{
var frame = new StackFrame(1);
var method = frame.GetMethod();
var type = method.DeclaringType;
var name = method.Name;
var log = LogManager.GetLogger(type);
// LOG ID HERE
ThreadContext.Properties["MessageId"] = OperationContext.Current.IncomingMessageHeaders.MessageId; // SOMETHING HERE
}
I've tried OperationContext.Current.IncomingMessageHeaders.MessageId but thats always null.
I've read about wcf instance correlation but i don't need something that complicated (e.g. unique across different method calls).
Please if anyone can help that would be much apprieciated. Thanks in advance.
Plain SOAP or REST has no such identification included in messages. You must use some additional feature or transport protocol (for example MSMQ) supporting identifications of messages. In case of MessageId you have to use SOAP service with WS-Addressing and this information must be passed from client.
