MVC 3 + REST return custom http error?

Question

In my application I am trying to get it so that when a REST api call is made, if there is an error that it return a proper status code then either Json or Xml in the body of the response.

So 400: { 'ErrorCode': '400', 'Reason' : 'You did something wrong..' }

or 400: <Error><ErrorCode>400</ErrorCode><Reason>You did something wrong</Reason></Error>

However I can't seem to find how to set the status and body to make this happen. Using fiddler inspect whats being passed back and fourth I've found that if I return a normal ActionResult then I can return the body message ok but the status is 200. If I use HttpException then I can set the status code but the body message is returned as a large html document. I've tried using HttpStatusCodeResult but that just seems to fail and return a 302.

I'm a bit stumped.

Pretty sure thrown exceptions are passed back over Rest. Unless you have it disabled somewhere — IAmGroot

Try Response.StatusCode = (int)HttpStatusCode.BadRequest; in your action method. Check out this article at develoq for a short tutorial: http://develoq.net/2011/returning-a-body-content-with-400-http-status-code/

Web API can handle this in various ways, but if you want to stick to ASP.NET MVC then use the code below:

 Response.StatusCode = 500;
 Response.TrySkipIisCustomErrors = true;
 return Content("Error description goes here.", "text/plain");

Check out MVC 4 Beta, there is a new feature called Web API that will help you solve this issue.
