如何在电报机器人中添加inlineKeyboard的URL

Question

我想创建一个按钮，当我单击它时，将在电报中将文件发送给我。

from config import TOKEN

from telegram import MessageEntity, ReplyKeyboardMarkup, Update
from telegram import InlineKeyboardButton, InlineKeyboardMarkup

from telegram.ext import Updater
from telegram.ext import CallbackContext
from telegram.ext import CommandHandler
from telegram.ext import MessageHandler, Filters
from telegram.ext import CallbackQueryHandler

import logging
import urllib.request , json

updater = Updater(token= TOKEN, use_context= True)
dispathcer = updater.dispatcher

logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s', 
level=logging.INFO)

download_url_link = 'https://saavn.me/songs?link='
home_page = 'https://saavn.me/home'

def readjson(url):
   req = urllib.request.urlopen(url)
   return json.loads(req.read().decode())

def start(update: Update, context: CallbackContext):
   text= "Welcome @{username}".format(username = update.effective_user.username)
   update.message.reply_text(text)

def download(update: Update, context: CallbackContext):
  x = update.message.parse_entities(types = MessageEntity.URL)
  msg = update.message.reply_text("Working on it...")
  for i in x:
      try:
          rjson = read_json(end_point_link + x[i])
          name = rjson["results"]['name'] 
          download_link = rjson["results"]["downloadUrl"][4]["link"]
          quality = rjson["results"]["downloadUrl"][4]["quality"]
          msg.delete()
          dl = update.message.reply_document(download_link, caption="Here is {} and quality is  {}".format(name, quality))
          keyboard = [
              [
                  InlineKeyboardButton('128KB', callback_data=dl),
                  InlineKeyboardButton('320kb', callback_data=dl),
              ]
          ]
          reply_markup = InlineKeyboardMarkup(keyboard)
          update.message.reply_text("Please choose:", 
          reply_markup=reply_markup)
       except:
           continue
         if 'error' in rjson:
           continue
         return
     msg.edit_text("I can't fetch from that url. try again!")

不要工作inlinekeyboard，只是发送给我链接下载，也不要显示我的按钮

start_handler = CommandHandler('start', start)
download_hundler = MessageHandler(Filters.entity(MessageEntity.URL), download)
button_handler = CallbackQueryHandler(button)


dispathcer.add_handler(start_handler)
dispathcer.add_handler(download_hundler)
dispathcer.add_handler(button_handler)


updater.start_polling()

我运行程序，并且文件发送给我，但它不问我128或320，它会自动发送文件为什么？

Answer 1

在键盘部分中，您应该为每个按钮具有唯一的回调数据。例如：

keyboard = [
              [
                  InlineKeyboardButton('128KB', callback_data='dl-128'),
                  InlineKeyboardButton('320kb', callback_data='dl-320'),
              ]
          ]

然后，您应该创建一个函数来处理回调查询：

def button(update: Update, context: CallbackContext):
  data = update.callback_query.data
  quality = int(data.split('-')[1])
  if quality == 128:
    # send 128kb file
  elif quality == 320:
    # send 320kb file

之后，您应该使用首选模式创建一个回调处理程序。对于此示例，将是：

button_handler = CallbackQueryHandler(button, pattern='dl-')
dispathcer.add_handler(button_handler)
