Python vk api how to send photo without uploading to disk?

Question

Python

How to send a photo without downloading it to disk (so as not to use it and not slow down an already slow process)?
I tried to send the received photo from requests directly to VK, but some error took off
Please help

Answer 1

Take the content of the photo into a variable, which is loaded with a post request. An example of a post to a group with an attached photo:

upload_url = vk_api.photos.getWallUploadServer(group_id=group_id)['upload_url']
r = requests.get(image_url)
image_data = r.content
r = requests.post(upload_url, files={'photo': (image_name, image_data) }).json()
d = {}
d['server'] = r['server']
d['photo'] = r['photo']
d['hash'] = r['hash']
d['group_id'] = group_id
photo_id = vk_api.photos.saveWallPhoto(**d)[0]['id']
vk_message = 'Сообщение'
vk_params = { 'message': vk_message, 'from_group': 1, 'owner_id': -group_id }
vk_params['attachments'] = '%s,%s' % (photo_id, image_url)
post_id = vk_api.wall.post(**vk_params)['post_id']

Hello, please tell us how you solved the problem vk_api.exceptions.ApiError: [100] One of the parameters specified was missing or invalid: photos_list is
invalid selenium, then I crop it to the desired size using Pillow(PIL) and try to send a byte representation of this screen, but in the Post-request that I send to VK I get the hash and the server, but the sheet with the photo is empty
I thought it might not be in that form I'm sending a VK request with a byte image. I decided to try to send a photo from the Internet using requests .content and I get the same error, although I did everything exactly as shurshur wrote . I honestly can't figure out what the problem is, why the photo is empty...
