📁 Telegram File Proxy

Introduction

Using this proxy you can provide links to files to users by file_id without exposing the bot's token. Extremely useful for the WebApp feature to use files from Telegram in your web app.

To get a link to a file, simply pass file_id of the file as the path:

http://telegram-file-proxy/<file_id>

Usage

Building from source

1. Build

go mod download && go mod verify && go build -o proxy

2. Run

./proxy --bot-token 12345:ABCDEFGHIJKLMNOPQRSTUVWXYZ

💡 Pro Tip! Run ./proxy --help to see all available command line arguments.

Using Docker Compose

version: "3"
services:
  telegram-file-proxy:
    image: deptyped/telegram-file-proxy
    ports:
      - "8080:80"
    environment:
      - BOT_TOKEN= # <-- place your bot token here
      - SERVER_PORT=80

Or configuration with command line arguments:

    ports:
      - "8080:80"
    command: --bot-token <place your bot token here> --server-port 80

Using Docker Compose with a Local Bot API Server

services:
  telegram-file-proxy:
    image: deptyped/telegram-file-proxy
    ports:
      - "8080:80"
    volumes:
      - "./data:/var/lib/telegram-bot-api"
    environment:
      - BOT_TOKEN= # <-- place your bot token here
      - SERVER_PORT=80
      - API_ROOT=http://bot-api:8081
      - API_LOCAL=1

  bot-api:
    image: aiogram/telegram-bot-api:latest
    ports:
      - "8081:8081"
    volumes:
      - "./data:/var/lib/telegram-bot-api"
    environment:
      - TELEGRAM_LOCAL=1
      # Create an application with api id and api hash (get them from https://my.telegram.org/apps)
      - TELEGRAM_API_ID= # <-- place your api id here
      - TELEGRAM_API_HASH= # <-- place your api hash here
