我正在编写一个程序来开发一个电报聊天机器人使用Node. js和node-telegram bot api模块。我想设置命令，当收到 /unsubscribe用户应该从机器人退订。我阅读了该模块的github文档，但找不到实现此功能的方法。https://github.com/yagop/node-telegram-bot-api/blob/master/doc/api.md
在本文档中，有一个方法deleteChat可用，但我不确定它是否适用于该模块。https://core.telegram.org/methods#working-with-chatssupergroupschannels
感谢任何建议或帮助，谢谢！
您需要一个数据库来将用户设置为“订阅”或“取消订阅”。
我会给你一个商店包的例子你需要以下包：
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!")
})
