ExGram.File (ex_gram v0.65.0)

Helpers for working with Telegram file downloads.

After retrieving file metadata with ExGram.get_file/2, use file_url/2 to generate the download URL for the file.

Summary

file()

Generate the full file URL ready to be downloaded.

@type file() ::
  String.t()
  | {:file, String.t()}
  | {:file_content, iodata() | File.Stream.t(), String.t()}

@spec file_url(
  ExGram.Model.File.t(),
  keyword()
) :: String.t()

Generate the full file URL ready to be downloaded.

First, retrieve the file metadata:

{:ok, file} = ExGram.get_file(file_id)

Then generate the download URL:

ExGram.File.file_url(file)

You can pass the usual :bot and :token params:

ExGram.File.file_url(file, bot: :my_bot)
ExGram.File.file_url(file, token: "MyBotToken")
