Unable to use PostFile to upload image - servicestack

Question

I am trying to use PostFile to upload an image. As a simple example I have the following DTO:
[Route("/Pictures/{Id}", "GET, PUT, DELETE")]
public class Picture
{
public int Id { get; set; }
}
public class PictureResponse : IHasResponseStatus
{
public int Id { get; set; }
#region Implementation of IHasResponseStatus
public ResponseStatus ResponseStatus { get; set; }
#endregion
}
My GET works fine:
public override object OnGet(Picture request)
{
var memoryStream = new MemoryStream();
PictureRepository.Get(request.Id).Save(memoryStream, ImageFormat.Png);
return new HttpResult(memoryStream, "image/png");
}
But my PostFile blows up:
var imagePathInfo = new FileInfo(#"C:\Users\Mark\Downloads\avatars\symang.jpg");
var serviceClient = new JsonServiceClient("http://localhost:52712/api")
serviceClient.PostFile<PictureResponse>("/Pictures/{0}".Fmt(id), imagePathInfo, MimeTypes.GetMimeType(imagePathInfo.Name));
Here's the error and stack trace:
Server Error in '/' Application.

I'm sure I must be misunderstanding how to use PostFile. By the way, I never hit my OnPost method on my service. Thanks for any insights.

Answer 1

PostFile does a HTTP POST.
But your service only allows GET, PUT and DELETE because of your route in the first line of your example code:
[Route("/Pictures/{Id}", "GET, PUT, DELETE")]
Solution:
Either include POST in your route:
[Route("/Pictures/{Id}", "GET, PUT, DELETE, POST")]
...or just omit the HTTP verbs:
[Route("/Pictures/{Id}")]
