如果你按下上传照片按钮一次，机器人将发送照片1次。但是，如果你按下这个按钮超过1次，照片将发送给你多次按下这个按钮之前。包括点击的次数之前，以前的照片被发送

const keyboard = {
    reply_markup:{
        keyboard: [
            [{text: 'About Bot'}, {text: 'Upload Photo'}]
        ]
    }
}

bot.onText(/\/start/, async msg => {
    await bot.sendMessage(h.id(msg), `Choose any`,keyboard)
})

bot.on('message', msg => {
    switch (msg.text){
        case 'Upload Photo':
            uploadPhoto(h.id(msg))
            break
        case 'About Bot':
            break
    }
})

const uploadPhoto = async (chatId) => {
    await bot.sendMessage(chatId, 'Send me a photo')
    bot.on('photo', async (msg) => {
        const photo = msg.photo[2].file_id
        await bot.sendPhoto(channelId, photo)
        await bot.sendMessage(chatId, 'Photo is sent')
    })
}

按下按钮并成功发送照片后，下一张照片应仅出现一次
