XAI-Telegram-Bot

Set Up Telegram Bot

• Search BotFather(make sure it has the blue tick) and joint the channel

• Enter /newbot command and define your bot name and username
• Note the token (HTTP API)

Find Chat ID

It's easy to get from telegram web.

• Login Telegram Web
• Open your bot channel (It looks like https://web.telegram.org/a/#123456789)
• Remove the scheme, the hostname and the path and you get #123456789
• Replace # with 100 and that's your chat id (100123456789 in this case)

pip install python-telegram-bot

import subprocess
import os
from telegram import Bot, Update
from telegram.ext import CommandHandler, CallbackContext, Updater

# Replace 'YOUR_BOT_TOKEN' with your actual bot token
TOKEN = 'YOUR_BOT_TOKEN'

# Replace 'YOUR_CHAT_ID' with the chat ID where you want to send the logs
CHAT_ID = 'YOUR_CHAT_ID'

# Command to trigger the logs retrieval
COMMAND = 'get_logs'

def start(update: Update, context: CallbackContext) -> None:
    update.message.reply_text('Bot is running. Send /get_logs to fetch screen session logs.')

def get_logs(update: Update, context: CallbackContext) -> None:
    try:
        # Get the chat ID from the update
        chat_id = update.message.chat_id

        # Run the command to get the logs from the 'YOUR_SCREEN_NAME' screen session
        logs = subprocess.check_output(['screen', '-S', 'YOUR_SCREEN_NAME', '-X', 'hardcopy', '/tmp/node_logs.txt'])

        # Read the logs from the temporary file
        with open('/tmp/node_logs.txt', 'r') as file:
            logs_content = file.read()

        # Send the logs to the chat ID obtained from the update
        context.bot.send_message(chat_id=chat_id, text='Screen session logs:\n' + logs_content)

    except subprocess.CalledProcessError as e:
        context.bot.send_message(chat_id=chat_id, text='Error retrieving logs: {}'.format(str(e)))

if __name__ == '__main__':
    # Create the updater and pass it the bot's token
    updater = Updater(token=TOKEN, use_context=True)

    # Get the dispatcher to register handlers
    dp = updater.dispatcher

    # Register command handlers
    dp.add_handler(CommandHandler("start", start))
    dp.add_handler(CommandHandler(COMMAND, get_logs, pass_update_queue=True, pass_job_queue=True, pass_chat_data=True))

    # Start the Bot
