How to make ASP.NET Web API to only return XML?
I'm trying to send a get request to ASP.NET Web API and get back a XML to parse it in my Android app. it returns XML when I try the link via web browser, but it return JSON when Android app send the request. how to fix it in a way it only sends XML? thanks
You could remove the JSON formatter if you don't intend to serve JSON:
var formatters = GlobalConfiguration.Configuration.Formatters;
formatters.Remove(formatters.JsonFormatter);
You also have the possibility to explicitly specify the formatter to be used in your action:
public object Get()
{
var model = new
{
Foo = "bar"
};
return Request.CreateResponse(HttpStatusCode.OK, model, Configuration.Formatters.XmlFormatter);
}
You could also force the accept header on all requests to be application/xml by using a MessageHandler
public class ForceXmlHandler : DelegatingHandler
{
protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, System.Threading.CancellationToken cancellationToken)
{
request.Headers.Accept.Clear();
request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xml"));
return base.SendAsync(request, cancellationToken);
}
}
Just add this message handler to the configuration object.
config.MessageHandlers.Add(new ForceXmlHandler());
You can remove JSON formatter them in Application_Start
Use
GlobalConfiguration.Configuration.Formatters.Remove(GlobalConfiguration.Configuration.Formatters.JsonFormatter);
