如何将Bot设置为自动欢迎消息或新加入成员或订户电报的群组规则

import requests

def send_welcome_message(chat_id):
    bot_token = "Your_Bot_Token"
    message = "Welcome to the group! We are glad to have you here."

    api_url = f"https://api.telegram.org/bot{bot_token}/sendMessage"
    payload = {
        "chat_id": chat_id,
        "text": message
    }

    response = requests.post(api_url, json=payload)
    if response.status_code == 200:
        print("Welcome message sent successfully.")
    else:
        print("Failed to send welcome message.")

# 在新成员加入时调用该函数
# chat_id是群组的唯一标识符，可以从消息事件中获取
def on_new_member_joined(chat_id):
    send_welcome_message(chat_id)

# 在订户加入时调用该函数
# chat_id是群组的唯一标识符，可以从消息事件中获取
def on_new_subscriber_joined(chat_id):
    send_welcome_message(chat_id)

# 示例调用
chat_id = "Your_Group_Chat_ID"
on_new_member_joined(chat_id)
