Examples

HttpExceptionDescriptorResponseHandlerDecoratorExtensions provides extension methods on Decorator.Enclose for registering additional response handlers that control how HTTP exception descriptors are serialized and returned. This example creates an initial HttpExceptionDescriptorResponseHandler for application/json with a 500 Internal Server Error status, wraps a List<HttpExceptionDescriptorResponseHandler> containing it, and calls AddResponseHandler with an options delegate specifying a custom content type, ContentFactory, and StatusCodeFactory. After execution, the list contains both handlers configured for different response scenarios in the error pipeline.

            {
                Content = new StringContent(ed.Message)
            });
        var list = new List<HttpExceptionDescriptorResponseHandler> { handler };

        Decorator.Enclose(list).AddResponseHandler(o =>
        {
            o.ContentType = new MediaTypeHeaderValue("application/json");
            o.ContentFactory = ed => new StringContent(ed.Message);
            o.StatusCodeFactory = ed => HttpStatusCode.InternalServerError;
        });
    }
