以前已經謝好了批量工具自動獲取用於資訊，現在需要優化，預先判斷是否註冊，然後再爬取資訊。

以前程式碼涉及隱私和漏洞，不便釋出，檢測是否註冊為公開client api，實現基於 python，不需要手機註冊。程式碼如下：

from telethon import TelegramClient
import re,time
from telethon.tl.functions.auth import CheckPhoneRequest


api_id = 1557
api_hash = '8da85b0d5bfe62527e5b244c209159c3'

class MyTG(TelegramClient):
    def checkPhone(self,phone,no=None):
        phone = self.parse_phone(phone)
        res=self(CheckPhoneRequest(phone_number=phone))
        if no:
            print (no,phone,res.phone_registered)
        else:print (phone,res.phone_registered)
        return res.phone_registered

    def parse_phone(self,phone):
        if isinstance(phone, int):
            return str(phone)
        else:
            phone = re.sub(r'[+()\s-]', '', str(phone))
            if phone.isdigit():
                return phone

client = MyTG('zbsb', api_id, api_hash)
client.connect()

d='''
12345678
23456789
34567890'''
d=d.split()
for n,i in enumerate(d):

    phone=i
    client.checkPhone(phone,n+1)
