|
|
Sends a file to the specified entity.
|
|
|
|
Args:
|
|
entity (`entity`):
|
|
Who will receive the file.
|
|
|
|
file (`str` | `bytes` | `file` | `media`):
|
|
The path of the file, byte array, or stream that will be sent.
|
|
Note that if a byte array or a stream is given, a filename
|
|
or its type won't be inferred, and it will be sent as an
|
|
"unnamed application/octet-stream".
|
|
|
|
Furthermore the file may be any media (a message, document,
|
|
photo or similar) so that it can be resent without the need
|
|
to download and re-upload it again.
|
|
|
|
If a list or similar is provided, the files in it will be
|
|
sent as an album in the order in which they appear, sliced
|
|
in chunks of 10 if more than 10 are given.
|
|
|
|
caption (`str`, optional):
|
|
Optional caption for the sent media message.
|
|
|
|
force_document (`bool`, optional):
|
|
If left to ``False`` and the file is a path that ends with
|
|
the extension of an image file or a video file, it will be
|
|
sent as such. Otherwise always as a document.
|
|
|
|
progress_callback (`callable`, optional):
|
|
A callback function accepting two parameters:
|
|
``(sent bytes, total)``.
|
|
|
|
reply_to (`int` | :tl:`Message`):
|
|
Same as `reply_to` from `send_message`.
|
|
|
|
attributes (`list`, optional):
|
|
Optional attributes that override the inferred ones, like
|
|
:tl:`DocumentAttributeFilename` and so on.
|
|
|
|
thumb (`str` | `bytes` | `file`, optional):
|
|
Optional thumbnail (for videos).
|
|
|
|
allow_cache (`bool`, optional):
|
|
Whether to allow using the cached version stored in the
|
|
database or not. Defaults to ``True`` to avoid re-uploads.
|
|
Must be ``False`` if you wish to use different attributes
|
|
or thumb than those that were used when the file was cached.
|
|
|
|
parse_mode (`object`, optional):
|
|
See the `TelegramClient.parse_mode` property for allowed
|
|
values. Markdown parsing will be used by default.
|
|
|
|
voice_note (`bool`, optional):
|
|
If ``True`` the audio will be sent as a voice note.
|
|
|
|
Set `allow_cache` to ``False`` if you sent the same file
|
|
without this setting before for it to work.
|
|
|
|
video_note (`bool`, optional):
|
|
If ``True`` the video will be sent as a video note,
|
|
also known as a round video message.
|
|
|
|
Set `allow_cache` to ``False`` if you sent the same file
|
|
without this setting before for it to work.
|
|
|
|
Notes:
|
|
If the ``hachoir3`` package (``hachoir`` module) is installed,
|
|
it will be used to determine metadata from audio and video files.
|
|
|
|
Returns:
|
|
The `telethon.tl.custom.message.Message` (or messages) containing
|
|
the sent file, or messages if a list of them was passed.
