Using Python, how can I retrieve several MySQL rows and display them via a Telegram bot while allowing only specific phone numbers to interact? Example code:
def retrieve_entries(search_term):
# Simulate database lookup
entries = [{"date": "2023-10-12", "metric": 42}]
return entries
def process_update(update):
approved_numbers = ["+1234567890"]
if update.get('phone') in approved_numbers:
return retrieve_entries(update.get('filter'))
return "Access Denied"
hey, try verifiying the user ph# before fetching the mysql rows and then send each entry individually. i used a middleware check and it made access smoother and limits queries from unautherized numbers. remeber, smaller approved list means less overhead
In my experience, managing access by verifying phone information early on helps streamline the process. One effective approach is to implement an initial check that blocks unauthorized requests before any database calls are made. This not only reduces unnecessary load on your MySQL server but also enhances security. I have also combined this with parameterized queries to minimize SQL injection risks. Additionally, consider handling database results asynchronously; this ensures that the bot remains responsive while processing multiple records concurrently.
From my experience, it is important to structure your code so that verification happens as early as possible, which saves resources and enhances security. One technique is to first check if the incoming phone number is in a predefined list and then only proceed with any database calls if the check passes. This prevents unnecessary loads on the database and helps protect against potential rough attacks. Incorporating error handling through try-except blocks also makes the system more robust when dealing with unexpected input or database failures. Consider logging access attempts as well.
