如何检查用户是否订阅了特定的电报频道Python / PyTelegramBotApi?

问题描述

我正在使用 PyTelegramBotApi库编写 Telegram机器人,我希望 实现检查用户对特定电报的订阅功能频道 ,如果没有,则提供订阅。预先感谢您的回答!

解决方法

使用getChatMember方法检查用户是否为频道成员。

getChatMember

使用此方法获取有关a的成员的信息 聊天。成功返回一个ChatMember对象。

import telebot

bot = telebot.TeleBot("TOKEN")

CHAT_ID = -1001...
USER_ID = 700...

result = bot.get_chat_member(CHAT_ID,USER_ID)
print(result)

bot.polling()

采样结果:

如果用户是会员,您会收到用户信息

{'user': {'id': 700...,'is_bot': False,'first_name': '','username': None,'last_name': None,... }

否则为例外

telebot.apihelper.ApiTelegramException: A request to the Telegram API was unsuccessful. Error code: 400 Description: Bad Request: user not found

在项目中如何使用它的示例

import telebot
from telebot.apihelper import ApiTelegramException

bot = telebot.TeleBot("BOT_TOKEN")

CHAT_ID = -1001...
USER_ID = 700...

def is_subscribed(chat_id,user_id):
    try:
        bot.get_chat_member(chat_id,user_id)
        return True
    except ApiTelegramException as e:
        if e.result_json['description'] == 'Bad Request: user not found':
            return False

if not is_subscribed(CHAT_ID,USER_ID):
    # user is not subscribed. send message to the user
    bot.send_message(CHAT_ID,'Please subscribe to the channel')
else:
    # user is subscribed. continue with the rest of the logic
    # ...

bot.polling()
