Using updateStatusWithMedia with in-memory image data

[danxshap]

Back in 2.7, I could make the following call:

t._media_update(settings.TWITTER_SHARE_URL,
    {'media[]': image_data}, status=message)

But the internal _media_update function has since been removed, so I can't upgrade Twython. Any chance it could come back or some other solution for posting in-memory image data could be added?

Or perhaps I'm missing something and there's a way to do this with the latest Twython?

Thanks!

You can do

t.post(URL, params={'status': message}, files={'file': open('report.jpg', 'rb')})

That should work!

@michaelhelmick in that case isn't open() looking for a file on the disk? I don't have any files on the disk, I just have image bytes in a variable, and I can't save to the disk for performance reasons.

[michaelhelmick]

Can you put the bytes into a StringIO?

from PIL import Image
from StringIO import StringIO
i = Image.open(StringIO(my_bytes))

Or do you absolutely only need to pass bytes? There might be a way. But I'm driving and hard to look it up right now haha

@michaelhelmick hmm, when I pass a PIL Image like you suggested above, it fails when requests tries to call .read(), which doesn't exist on the PIL image object, and if I try passing just the StringIO I get a "Missing or invalid url parameter" error.

As in you've tried...

from StringIO import StringIO
from twython import Twython
t = Twython(...)
t.post(URL, params = {'status': message}, files={'file': StringIO(...)})

[danxshap]

@ryanmcgrath Yes sir.

[ryanmcgrath]

Hmmm, the following seems to post successfully for me (e.g, no 403, etc). Try this perhaps?

from StringIO import StringIO
t.post('/statuses/update', params = {'status': 'Testing'}, files = {
    'file': StringIO(open('sidebar_pic.png').read())
})

[ryanmcgrath]

Ah, hold, I see the issue.

[ryanmcgrath]

Here we go, this should do what you want. Just worked for me.

from StringIO import StringIO
from twython import Twython

t = Twython(...)
img = open('img_url').read()
t.post('/statuses/update_with_media', params = {'status': 'Testing New Status'}, files = {
    'media': StringIO(img)
    # 'media': ('OrThisIfYouWantToNameTheFile.lol', StringIO(img))
})

There's a larger question of whether we should have this native in the library, but... I wanna sleep on that one I think.

[danxshap]

This above works great - thank you!

[ryanmcgrath]

Nice! I'm going to close this for now, but we might want to look at trying to detect if a StringIO object is passed to the media status update method in the future. Let us know if you notice anything else!

[michaelhelmick]

If you take a look at my "requests-Facebook" library, @ryanmcgrath, I am doing something pretty cool. I'm allowing the user to pass bytes (I think off the top of my head) so they can edit the image and whatnot before hand. In the readme there is an example of how to resize an image then post it to Facebook

I mean, that same thing can be accomplished by... editing the image beforehand, then passing it in via StringIO, no?

[michaelhelmick]

I think that's what I'm doing in the lib. I'd have to see. Haven't touched in a couple months
