Issue uploading file: IOS + Android

[valinaga]

Hi,

I just upgraded to 3.0.0-beta and now the files doesn't seems to get to the server.
If I use in the headers 'Content-Type': 'x-www-form-urlencoded', or nothing at all, the data does not get to the server, although the component shows the progress and completion correctly.
If I add 'Content-Type': 'multipart/form-data' to headers, then I get an error on the server:
Unexpected error while processing request: invalid byte sequence in UTF-8.
I use Ruby on Rails and the service was tested successfully with a standard multipart form in html.
Any idea?
Anyone has a reference implementation of server which is actually working, to test the component?
Thanks!

Hi, I'm looking into it but won't be able to do much until this Thursday June 15. I would really appreciate any code you could share. In the meantime, maybe consider downgrading to a previous version that worked for you.

We had that same error on iOS a while ago with 0.1.2 version of the module. Solution was to set a header:

Content-Type: application/octet-stream

The problem is in Ruby on Rails middleware - rack.
It treats both application/x-www-form-urlencoded and multipart/form-data like a form data (see here) and therefore tries to parse it as a regular form data(see here). But the file itself is not actually sent as a form, more like a huge string in request body.
We use paperclip to work with uploads and in order to get uploaded file we use the following code:

file = Paperclip::StringioAdapter.new(request.body)

Hope it helps!
