Brion Vibber commented on CB-622:
---------------------------------
I don't think FileTransfer is actually part of W3C's FileAPI ... it feels very
PhoneGappy in how it takes two callbacks and has a couple extra paramaeters
tacked on. :)
I think the FileAPI-friendly way of doing this is to pass File or Blob objects
into a FormData object, then send that into an XMLHTTPRequest:
https://developer.mozilla.org/En/XMLHttpRequest/Using_XMLHttpRequest#Using_FormData_objects
This seems to live in the XMLHttpRequest2 spec:
http://www.w3.org/TR/XMLHttpRequest2/#interface-formdata
This also would sidestep FileTransfer-specific feature requests like:
https://issues.apache.org/jira/browse/CB-51 (support PUT as well as POST)
https://issues.apache.org/jira/browse/CB-52 (HTTP basic auth)
https://issues.apache.org/jira/browse/CB-200 (support uploading multiple files
in one request)
since all those things can be done with FormData+XHR.
... there may already be native FormData implementations in the WebKit
available (confirmed it claims to be there in iOS 4.3, iOS 5.1, and Android
4.0.2) so I don't know how hard it would be to supplement them or make them
interact with other objects.
> FileTransfer interface should provide progress monitoring

> Key: CB-622
> URL: https://issues.apache.org/jira/browse/CB-622
> Project: Apache Callback
> Issue Type: Improvement
> Components: Android, BlackBerry, iOS, WP7
> Affects Versions: 1.7.0
> Environment: Checked docs for iOS and Android, and in general.
> Reporter: Brion Vibber
> Labels: FileTransfer, file
>
> The FileTransfer upload and download interface seems to provide no way to
> monitor progress of the upload/download, other than waiting for the entire
> transfer to complete or fail.
> Being able to pass another callback for progress monitoring could be a useful
> interface, this might get called with a byte count or something.
