Hi guys, I'm developing a webservice in Yesod that needs to accept multipart POST's with image data in them. This webservice will be used mainly by mobile devices. My handler that takes care of receiving the image works correctly when receiveng a POST crafted by google chrome (from a multipart/form-data encoded form), but when receiving a multipart post from a mobile device it fails to parse the multipart request arguments. I've setup a ruby on rails application with a similar handler, and both request from my mobile device and from a browser work, so I'm leaning towards thinking this is a yesod/wai issue. This is an excerpt from my handler, that I use to debug this: myHandler = do (params, files) <- runRequestBody liftIO $ putStrLn $ "params " ++ show params When requesting from the mobile device it just shows an empty list. I have dumps of both multipart requests, they seem pretty similar with the main differences being: * the multipart boundaries are longer in the browser request. * the request from the mobile device adds a trailing semicolon to the content-type of each part (except for the image) I attached the request that's not parsing correctly Any help will be greatly appreciated, thanks in advance! --nubis :)
