How to upload file?
|
|
###################
|
|
|
|
As says `official Telegram Bot API documentation <https://core.telegram.org/bots/api#sending-files>`_
|
|
there are three ways to send files (photos, stickers, audio, media, etc.):
|
|
|
|
If the file is already stored somewhere on the Telegram servers or file is available by the URL,
|
|
you don't need to reupload it.
|
|
|
|
But if you need to upload new file just use subclasses of `InputFile <types/input_file.md>`__.
|
|
|
|
Here is available three different builtin types of input file:
|
|
|
|
- :class:`aiogram.types.input_file.FSInputFile` - `uploading from file system <#upload-from-file-system>`__
|
|
- :class:`aiogram.types.input_file.BufferedInputFile` - `uploading from buffer <#upload-from-buffer>`__
|
|
- :class:`aiogram.types.input_file.URLInputFile` - `uploading from URL <#upload-from-url>`__
|
|
|
|
.. warning::
|
|
|
|
**Be respectful with Telegram**
|
|
|
|
Instances of `InputFile` is reusable.
|
|
That's mean you can create instance of InputFile and sent this file multiple times but Telegram
|
|
is not recommend to do that and when you upload file once just save their `file_id`
|
|
and use it in next times.
|
|
|
|
Upload from file system
|
|
=======================
|
|
|
|
By first step you will need to import InputFile wrapper:
|
|
|
|
.. code-block::
|
|
|
|
from aiogram.types import FSInputFile
|
|
|
|
Then you can use it:
|
|
|
|
.. code-block::
|
|
|
|
cat = FSInputFile("cat.png")
|
|
agenda = FSInputFile("my-document.pdf", filename="agenda-2019-11-19.pdf")
|
|
|
|
|
|
.. autoclass:: aiogram.types.input_file.FSInputFile
|
|
:members:
|
|
|
|
|
|
Upload from buffer
|
|
==================
|
|
|
|
Files can be also passed from buffer
|
|
(For example you generate image using `Pillow <https://pillow.readthedocs.io/en/stable/>`_
|
|
and the want's to sent it to the Telegram):
|
|
|
|
Import wrapper:
|
|
|
|
.. code-block::
|
|
|
|
from aiogram.types import BufferedInputFile
|
|
|
|
And then you can use it:
|
|
|
|
.. code-block::
|
|
|
|
text_file = BufferedInputFile(b"Hello, world!", filename="file.txt")
|
|
|
|
.. autoclass:: aiogram.types.input_file.BufferedInputFile
|
|

|
|
|
Upload from url
|
|
===============
|
|
|
|
If you need to upload a file from another server, but the direct link is bound to your server's IP,
|
|
or you want to bypass native `upload limits <https://core.telegram.org/bots/api#sending-files>`_
|
|
by URL, you can use :obj:`aiogram.types.input_file.URLInputFile`.
|
|
|
|
Import wrapper:
|
|
|
|
.. code-block::
|
|
|
|
from aiogram.types import URLInputFile
|
|
|
|
And then you can use it:
|
|
|
|
.. code-block::
|
|
|
|
image = URLInputFile(
|
|
"https://www.python.org/static/community_logos/python-powered-h-140x182.png",
|
|
filename="python-logo.png"
|
|
)
|
|
|
|
.. autoclass:: aiogram.types.input_file.URLInputFile
