向电报机器人的所有用户发送消息

问题描述

我正在使用 pyTelegramBotAPI (telebot)。我需要向所有机器人用户发送消息，但经过多次尝试，我的代码根本不起作用（没有错误，但它不发送消息）。我已经将 user_id 存储在 sqlLite 数据库中的名为“test”的表中。将不胜感激一些帮助。

我的代码：

import sqlite3
import telebot

TOKEN = ""
bot = telebot.TeleBot(TOKEN)

conn = sqlite3.connect('db/database.db',check_same_thread=False)
cursor = conn.cursor()

def db_table_val(user_id: int,user_name: str,user_surname: str,username: str):
    cursor.execute('INSERT INTO test (user_id,user_name,user_surname,username) VALUES (?,?,?)',(user_id,username))
    conn.commit()

@bot.message_handler(commands=['start'])
def start_message(message):
    bot.send_message(message.chat.id,'Welcome!')

@bot.message_handler(content_types=['text'])
def get_text_messages(message):
    if message.text.lower() == 'Hi!':
        bot.send_message(message.chat.id,'Hi! You are cool!')
        
        us_id = message.from_user.id
        us_name = message.from_user.first_name
        us_sname = message.from_user.last_name
        username = message.from_user.username
        
        db_table_val(user_id=us_id,user_name=us_name,user_surname=us_sname,username=username)

@bot.message_handler(commands=['newrm'])
def step_Set_Rm(message):
    cid = message.chat.id
    userRm = message.text
    conn = sqlite3.connect("database.db")
    cursor = conn.cursor()
    cursor.execute("SELECT user_id FROM test")
    users_list = cursor.fetchall()
    bot.send_message(users_list,userRm)
    conn.commit()
    conn.close()
    bot.send_message(message.chat.id,'Отправлено!')

bot.polling(none_stop=True)

解决方法

您可以在不使用任何第三方模块的情况下将用户 id 列在列表中：

import telebot

TOKEN = ""
bot = telebot.TeleBot(TOKEN)

admin = # your chat id
users = []

@bot.message_handler(commands=['start'])
def start_message(msg):
    bot.send_message(msg.chat.id,'Welcome!')
    if msg.chat.id not in users: # if the id isn't already in the users list
        users.append(msg.chat.id)

@bot.message_handler(commands=['send_at_all'])
def sendAtAll(msg):
    if msg.chat.id == admin: # only if YOU start the command the message will be sent
        for id in users: # for every user that has start the bot
            bot.send_message(id,"I'm sending this message at all the users")

# If an user wants to stop the notifications...

@bot.message_handler(commands=['unsubscribe'])
def sendAtAll(msg):
    del users[msg.chat.id]
    bot.send_message(msg.chat.id,"If you want to receive the notification click /start")


# Every time you are going to restart the bot polling the content of the users list will be deleated so...

@bot.message_handler(commands=['save_user_list'])
def sendAtAll(msg):
    if msg.chat.id == admin:
        bot.send_message(admin,users) 
# the list will be sent to your telegram chat,when you activate the bot you can add the list manually

bot.polling()
