DynamicApiControllerBuilder - Using custom action filter #532

jaq316 created 8 years ago

I have an application service that is called by an external service and this service requires the response to be a specific XML format. How can I add a custom action filter to return the correct XML response?

My code currently looks like this:

DynamicApiControllerBuilder
                .For<ISomeAppService>("app/some")
                .ForMethod("Process")
                .WithVerb(Abp.Web.HttpVerb.Get)
                .WithFilters(/* ??? How do I modify the response using a custom action filter? *?)
                .Build();

Maybe no one knows :)

I don't know how to make it with filters. Can you create such a filter for regular Web API controllers (out of ABP)?

For anyone that wants to do the same... Here is the solution:

Create the filter class:

public class PlainTextResponseActionFilter : ActionFilterAttribute, IActionFilter, IFilter
    {

        public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
        {
            var abpAjaxContent = actionExecutedContext.Response.Content as ObjectContent<Abp.Web.Models.AjaxResponse>;
            if (abpAjaxContent != null)
            {
                var previousValue = abpAjaxContent.Value as Abp.Web.Models.AjaxResponse;
                actionExecutedContext.ActionContext.Response.Content = new StringContent(previousValue.Result.ToString());
            }
            else
                base.OnActionExecuted(actionExecutedContext);
        }

    }

Reference the class in the WithFilters method of the DynamicApicontrollerBuilder

DynamicApiControllerBuilder
                .For<ISomeAppService>("app/some")
                .ForMethod("Process")
                .WithVerb(Abp.Web.HttpVerb.Get)
                .WithFilters(new PlainTextResponseActionFilter())
                .Build();
