如何通过Lua中的statuss / update_with_media将图像发布到Twitter

Question

I have problems building the header and/or body of the http-POST for a Twitter oAuth update_with_media call in Lua.

• I'm using multipart/form-data as Content-Type
• All oauth_* parameters are included in the body, including an oauth_signature .
• POSTing to url https://upload.twitter.com/1/statuses/update_with_media.json

The problem is I have no idea how to successfully add the image data (media[]) to the body, in addition to 'status' and the other oauth parameters.

Also, how do I calculate the Content-Length ?

As of yet, I'm constantly getting a 500 Internal Server Error back form Twitter.

Can anyone provide me with a code snippet to add image data (jpg) to a POST? I'm using the Corona SDK btw, if that makes any difference.
