Pyrogram CallBack function

Question

as per the Pyrogram library documentation, I'm trying to set the "phone_code" parameter with a callable function but I always get this error, can anyone help me?

from pyrogram import Client
import time

def codePhone(phone_number):
    print('numero')
    sleep (10)
    return '2154'

app = Client("my_account",phone_number='39**********',phone_code=codePhone)
with app:
    app.send_message("me", "Hi!")

the error:

Answer 1

Sorry, I don't think I fully understand the requirement here, but from the looks of it you need to make it work. So in that case, you need to understand what are you passing as the argument to the function.

Since the codePhone function takes an argument (phone_number) but in your Client class you're just sending it as callback reference which seems to be incorrect.

Also as per the documentation for the module (Pyrogram) here says that the phone_code argument needs to be string (most likely string of numbers -> '2154'). So try using that instead.

Let me know if that works for you.

TL;DR: Use

app = Client("my_account",phone_number='39**********',phone_code='2154')

Answer 2

You are using version 1.0.7, but support for callback functions for parameters for Client was removed in ver. 0.16.0

Removed support for callback functions for Client arguments like phone_number, phone_code, password, … in favour of a simpler and sequential authorization flow.

At the moment it expects that you supply str for phone_code .

Answer 3

phone_number parameter in Client class takes a string, not a function. If you want to automate the process of phone number logins:

from pyrogram import Client
from pyrogram.errors import SessionPasswordNeeded
import os

api_id    = input('API ID: ')
api_hash  = input('API HASH: ')
phone     = input('Phone Number (with +): ')

def connect():
    try:
        client = Client(phone, api_id, api_hash)
        client.connect()
        code   = client.send_code(phone)
        try:
            signed_in = client.sign_in(phone, code.phone_code_hash, input('Verification Code: '))
            client.accept_terms_of_service(signed_in.id)
        except SessionPasswordNeeded:
            client.check_password(input('Two-Step Verification password: '))
        client.disconnect()
    except Exception as ex:
        os.remove(f'{phone}.session')
        print(f'Error !\n\t`{type(ex).__name__}`\n\t{ex}')
        return

    with client as app:
        app.send_message('me', "Hey it's YOU!")

if __name__ == '__main__':
    connect()
