python-3.x - Python电报API回复键盘标记

Question

我是 python 新手。我正在尝试向 Telegram 应用程序中的用户发送显示带有两个按钮的自定义键盘的响应，但它给了我一个关于编码的错误。

我想知道我的错误在哪里。

import json
from urllib.request import urlopen
from urllib.parse import quote, unquote
import time

def Decode(telegram_response):
    decoded=''
    for line in telegram_response:
        decoded=decoded+line.decode('utf-8')
    return decoded

TOKEN = 'mytoken'
URL = 'https://api.telegram.org/bot{}/'.format(TOKEN)
cmd = 'getme'

telegram_response = urlopen(URL + cmd)
decoded = Decode(telegram_response)
gtm = json.loads(decoded)

status = True
while status:
    cmd = 'getUpdates'

    telegram_response = urlopen(URL + cmd)
    decoded = Decode(telegram_response)
    upds = json.loads(decoded)

    new_message = len(upds['result'])

if new_message !=0:

    msg = upds['result'][0]['message']
    chat_id = str(msg['chat']['id'])


    reply_markup = {'keyboard': [[{'text':'first button'}],[{'text':'second button'}]], 'resize_keyboard': True, 'one_time_keyboard': True}
    reply_markup = json.dumps(reply_markup)

    params = ({'chat_id': chat_id, 'reply_markup': reply_markup, 'disable_web_page_preview': 'true'})
    myresponse =urlopen(URL + 'sendMessage' + quote((params).encode('utf-8')))

构建强大机器人的简单方法是使用python-telegram-bot库。

我用一些主要的修复和功能重写了你的代码。希望它可以帮助您更深入地学习机器人。
