To develop a Telegram bot for monitoring, summarizing, and sending periodic overviews of channel posts, follow these steps:
Step 1: Set Up Your Environment
1. Install Python: Ensure you have Python installed on your system.
2. Install Required Libraries:
```python
pip install python-telegram-bot requests beautifulsoup4
```
Step 2: Create the Telegram Bot
1. Create a Bot on Telegram: Talk to [@BotFather](https://telegram.me/BotFather) to create a new bot. Note the API token provided.
Step 3: Develop the Bot
1. Monitor Telegram Channels:
```python
from telegram import Bot, Update
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters, CallbackContext
import requests
from bs4 import BeautifulSoup
TOKEN = 'YOUR_TELEGRAM_BOT_TOKEN'
CHANNELS = ['@example_channel_1', '@example_channel_2']
SUMMARY_PERIOD = 60 * 60 # in seconds (1 hour)
bot = Bot(token=TOKEN)
def summarize_text(text):
# Use a simple summarization logic or integrate with an NLP model
return text[:100] + '...'
def monitor_channels(context: CallbackContext):
summaries = []
for channel in CHANNELS:
url = f'https://t.me/s/{channel.strip("@")}'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
posts = soup.find_all('div', class_='tgme_widget_message_text')
for post in posts:
summaries.append(summarize_text(post.get_text()))
summary = '\n\n'.join(summaries)
bot.send_message(chat_id=context.job.context, text=summary)
def start(update: Update, context: CallbackContext):
context.job_queue.run_repeating(monitor_channels, SUMMARY_PERIOD, context=update.message.chat_id)
update.message.reply_text('Bot started! You will receive periodic summaries.')
updater = Updater(token=TOKEN, use_context=True)
dp = updater.dispatcher
dp.add_handler(CommandHandler('start', start))
updater.start_polling()
updater.idle()
```
2. Customize Channels and Summary Period:
```python
def add_channel(update: Update, context: CallbackContext):
new_channel = context.args[0]
if new_channel not in CHANNELS:
CHANNELS.append(new_channel)
update.message.reply_text(f'Channel {new_channel} added.')
else:
update.message.reply_text(f'Channel {new_channel} already in the list.')
def remove_channel(update: Update, context: CallbackContext):
channel = context.args[0]
if channel in CHANNELS:
CHANNELS.remove(channel)
update.message.reply_text(f'Channel {channel} removed.')
else:
update.message.reply_text(f'Channel {channel} not found.')
def set_period(update: Update, context: CallbackContext):
global SUMMARY_PERIOD
try:
new_period = int(context.args[0]) * 60
SUMMARY_PERIOD = new_period
update.message.reply_text(f'Summary period set to {new_period // 60} minutes.')
except ValueError:
update.message.reply_text('Invalid period. Please provide a number.')
dp.add_handler(CommandHandler('add_channel', add_channel))
dp.add_handler(CommandHandler('remove_channel', remove_channel))
dp.add_handler(CommandHandler('set_period', set_period))
```
3. Documentation:
Provide clear instructions on how to use the bot, including commands to add/remove channels and set the summary period.
Step 4: Ensure Security and Compliance
- Secure Your Bot: Implement security measures to ensure the bot only responds to authorized users.
- Adhere to Telegram's API Usage Policies: Follow Telegram's guidelines and avoid actions that may lead to the bot being banned.
Step 5: Deployment and Support
- Deploy: Host your bot on a server to keep it running continuously.
- Ongoing Support: Be prepared to troubleshoot issues and update the bot as needed.
By following these steps, you can create a robust Telegram bot for monitoring, summarizing, and sending periodic overviews of channel posts.
