I’m working on a Telegram bot using Python 3.12 with AIogram 3.x and Pyrogram 2.0.106. I’m stuck on user authorization.
My code doesn’t work reliably. Sometimes it fails to submit or throws other errors. The main issue is a [400 CODE_EXPIRED] error that stops everything. This happens even though I send the code to my chatbot within 10 seconds of receiving it. The code should still be valid at this point.
Here’s a simplified version of what I’m trying to do:
from aiogram import Bot, Dispatcher
from pyrogram import Client
async def authorize_user(phone_number):
client = Client('user_session', api_id=12345, api_hash='abcdef')
await client.connect()
try:
sent_code = await client.send_code(phone_number)
# Wait for user to input code
code = await get_code_from_user()
await client.sign_in(phone_number, sent_code.phone_code_hash, code)
await client.send_message('me', 'Login successful!')
except Exception as e:
print(f'Error: {e}')
finally:
await client.disconnect()
# Main bot logic
bot = Bot(token='YOUR_BOT_TOKEN')
dp = Dispatcher()
@dp.message_handler(commands=['start'])
async def start_auth(message):
await message.reply('Please enter your phone number')
# More code to handle user input and call authorize_user()
I’ve tried other libraries like Telethon, but Pyrogram seems to fit my needs best. Any ideas on how to fix the CODE_EXPIRED error or improve the authorization process?
I’ve encountered similar issues when working with Telegram bots and user authorization. One thing that helped me was implementing a retry mechanism with exponential backoff. This way, if the code expires or there’s a temporary network hiccup, the system automatically tries again.
Here’s a rough idea of how I approached it:
import asyncio
from pyrogram.errors import PhoneCodeExpired, PhoneCodeInvalid
async def authorize_user_with_retry(phone_number, max_retries=3):
for attempt in range(max_retries):
try:
return await authorize_user(phone_number)
except (PhoneCodeExpired, PhoneCodeInvalid) as e:
if attempt == max_retries - 1:
raise
wait_time = 2 ** attempt
print(f'Authorization failed. Retrying in {wait_time} seconds...')
await asyncio.sleep(wait_time)
# Use this function instead of authorize_user in your main logic
This approach has significantly improved the reliability of my authorization process. Also, make sure you’re handling rate limits properly and considering implementing a queue system if you’re dealing with multiple users simultaneously. Hope this helps!
yo, I’ve been there with telegram bots. here’s a trick: use a context manager for the client session. it’ll auto-disconnect even if there’s an error. like this:
async with Client('user_session', api_id=12345, api_hash='abcdef') as client:
# Your authorization code here
this way u don’t need to worry bout manually disconnecting. saves headaches!
Having worked extensively with Telegram bots, I can suggest a few improvements to your authorization process. First, consider implementing a session management system to store and reuse authorized sessions, reducing the need for frequent re-authentications. This can be done using Pyrogram’s session file feature.
Secondly, add more robust error handling. Specifically for the CODE_EXPIRED error, you could implement a mechanism to request a new code automatically if the previous one expires. Here’s a snippet to illustrate:
async def authorize_with_retry(client, phone_number, max_attempts=3):
for attempt in range(max_attempts):
try:
sent_code = await client.send_code(phone_number)
code = await get_code_from_user()
return await client.sign_in(phone_number, sent_code.phone_code_hash, code)
except PhoneCodeExpired:
if attempt < max_attempts - 1:
print('Code expired. Requesting a new one...')
else:
raise
This approach should significantly improve the reliability of your authorization process.
