Hi!
Does anybody know if it is possible to upload a base64 encoded file via the API? I've already examined SVGEdit extension by Brion Vibber (http://www.mediawiki.org/wiki/Extension:SVGEdit) to get behind the api file upload magic. But as SVG is just text it doesn't quite fit to my use case.
When I try to upload a base64 encoded file via the API (i.e. a JPEG) I just get a file with the base64 string (i.e. plaintext with base64 code) written to the MediaWiki file repo.
Any hints?

Are you using a client that generates a MIME multipart POST request for you, or are you doing that yourself? If you're generating one yourself, you can simply use the Content-Transfer-Encoding: base64 header to tell the web server that the file is base64-encoded. If you're using a library or client that builds an HTTP request for you, you'll probably have to decode the base64 encoding and hand the raw file contents to the library/client.

Since HTTP POSTs may contain binary data, you can send the file without any special encoding. That would usually be the best thing to do.
Theoretically, if you really wanted to base64-encode it you could include a "Content-Transfer-Encoding: base64" header in the MIME part for the file data.[1] But PHP doesn't handle this correctly,[2] so in practice you'll probably need to use 8bit or binary encodings instead.

Roan, Brad, thanks for the quick reply.
A few words about the use case: my colleague has got a java applet that generates an image and provides this image as base64 encoded string via a javascript interface. His javascript code grabs this string and uses the "FormMultipart" class from Brion Vibbers SVGEdit extension (modules/ext.svgedit.formmultipart.js) to send a request to the MediaWiki API. The "Content-Transfer-Encoding: base64" is set. The file that is created in the MediaWiki repo is corrupted.
So long, thanks for the hints. We will keep them in mind.
