How to get file_id in telegram?

Question

Bots

The task is this: I send a photo to the bot, and in response I want to see the file_id of this photo for further sending. I tried a lot, but the knowledge is not enough yet. I will be grateful for help

Answer 1

When sending a photo, you can get its file_id and next time send only it, for example:

files = {}
if photo_name in files:
    file_id = files[photo_name]
    bot.send_photo(message.chat.id, file_id)
else:
    with open(photo_name, "rb") as f:
        bot.send_chat_action(message.chat.id, "upload_photo")
        r = bot.send_photo(message.chat.id, f)
        file_id = r.photo[0].file_id
        files[photo_name] = file_id

For incoming messages:

@bot.message_handler(content_types=['photo'])
def image_message(message):
  file_id = message.photo[0].file_id
