如何使用node.js node-telegram-bot-api订阅和订阅用户订阅用户？

Question

我正在编写一个程序来使用node.js和node-telegram-bot-api模块开发电报聊天机器人。我想设置命令，以便在接收 /取消订阅后，应从机器人中取消订阅。我阅读了该模块的GitHub文档，但找不到实现此目的的方法。 https://github.com/yagop/ Node-Telegram-bot-api/blob/master/doc/api.md

在此DOC中，有一个方法DeleteChat可用，但是我不确定它是否可以与模块一起使用。 https：//core..telegram.telegram.telegram.telegram.org/methods#working-working-working-working-working-working-working-working-workssssssssssssupergroupsschannels

感谢任何建议或帮助，谢谢！

您需要一个数据库将用户设置为“订阅”或“未取消”

。软件包/存储“ rel =“ nofollow noreferrer”>商店软件包
您将需要以下包：

• 存储
• 节点telegram-bot-api

商店软件包是本地存储，当应用重新启动

下面给出的代码时，可能会重置您的想法，它只能创建订阅和退出的功能，您可以使用循环方法将新闻发送给“数组”中的用户

const TelegramBot = require('node-telegram-bot-api');

// replace the value below with the Telegram token you receive from @BotFather
const token = 'YOUR_TELEGRAM_BOT_TOKEN';
var store = require('store')
var subscribed_users = store.get('subscribed')
// Create a bot that uses 'polling' to fetch new updates
const bot = new TelegramBot(token, {polling: true});

// Matches "/echo [whatever]"
bot.onText('/start', (msg) => {
  // 'msg' is the received Message from Telegram
const chatId = msg.chat.id;
  bot.sendMessage(chatId, 'Welcome!\nUser /subscribe to subscribe to newsletter or /unsubscribe to unsubscribe to news letter');
});
bot.onText('/subscribe', (msg) => {
  if(!susbcribed_users){
  var subscribed_users = []
}
  const chatId = msg.chat.id;
  //retrive subscribed users array data
if(subscribed_users.includes(msg.chat.id)){
    bot.sendMessage(chatId, "You're already subscribed to newsletter!")
    return
}
var new_data = subscribed_users.push(msg.chat.id)
store.set('subscribed', new_data)
  bot.sendMessage(chatId, "You're subscribed to newsletter!")
 
})

bot.inText('/unsubscribe', (msg) => {
  const chatId = msg.chat.id;
  if(!subscribed_users.includes(msg.chat.id)){
    bot.sendMessage(chatId, "You're not subscribed to newsletter!")
    return
}
  const newArr = arr.filter(object => {
  return object !== msg.chat.id;
});
store.set('subscribed', newArr)
bot.sendMessage(chatId, "You're subscribed to newsletter!")
})
