Is RequestFilter Validation client dependent?

问题:

Should I expect Request Filter Validation (e.g. FluentValidation) to be triggered when instantiating a reference service via AppHostBase.ResolveService<>?

Thus far, I've only successfully received proper error responses to my C# application when using the typed clients (JsonServiceClient in this case specifically).

You are right. If you try use AppHostBase.ResolveService<T> it does not execute any of the registered request filters. Essentially it only resolves the Service from the AppHost dependancy container, you get back just the Service instance. Thus your validators aren't triggered.

ServiceStack v4:

As @mythz points out you can use the MQ entry point API of the HostContext to execute the call with the MQ request filters and thus have the validation run. To do this:

HostContext.ServiceController.ExecuteMessage(new Message<T>(requestDto), httpReq);

@mythz also notes you can execute a service using just a DTO, rather than having to determine the service and handling method to call, but in a similar fashion to AppHostBase.ResolveService<T> it doesn't trigger the request filters. Usage:

HostContext.ServiceController.Execute(requestDto, httpReq)

ServiceStack v3:

GetAppHost().Config.ServiceManager.ServiceController.ExecuteMessage(new Message<T>(requestDto), httpReq);
