Re: Image upload from App

[ve...@fit.fraunhofer.de]

I can see the photo(JPEG) being attached to the CouchDB server when I run
the application (Can see the size (KB) details, but the image does not
open, not readable). Anyone had similar problems? Here is the Android code
snippet written in Titanium Studio.

var image = event.media;
var xhr = Titanium.Network.createHTTPClient();
xhr.open('PUT','http://129.26.160.66:5984/mc/id100/attachment.jpg?rev=42-2fd65cfa04540fb9e73ee85a42111d2e');
xhr.setRequestHeader("Content-Type", "image/jpeg");
xhr.send({media:image});

Setting the Content-Type overrides Ti's handling of multipart forms.
Probably, Ti is still sending the data as if it were multipart, but with a
image/jpeg Content-Type. So the multipart document is uploaded even though
you're telling the server it's an image.

You probably need to not send Content-Type, and then you need to determine
what form element (media in { media: image }) that CouchDB expects to be
sent. If it's nested (a la Rails), do something like:

xhr.send({ "myobject[photo]": image });

Good luck with this... If you can avoid Titanium, I would recommend that
you do. I've spent countless nights doing basic things that should just
work (and do natively and in web browsers). At this point, I think I could
have written the app I'm working on in ARM assembler and spent less time
debugging. :(
