python - 如何修复电报机器人中的连接错误？

Question

我开始编写一个电报机器人，并为此使用了 freeCodeCamp 示例。

from telegram.ext import Updater, CommandHandler
import requests
import re
contents = requests.get('https://random.dog/woof.json').json()
image_url = contents['url']

def get_url():
    contents = requests.get('https://random.dog/woof.json').json()
    url = contents['url']
    return url

def get_image_url():
    allowed_extension = ['jpg','jpeg','png']
    file_extension = ''
    while file_extension not in allowed_extension:
        url = get_url()
        file_extension = re.search("([^.]*)$",url).group(1).lower()
    return url
def bop(bot, update):
    url = get_url()
    chat_id = update.message.chat_id
    bot.send_photo(chat_id=chat_id, photo=url)


def main():
    updater = Updater('<MY-PRIVATE-BOT-TOKEN>')
    dp = updater.dispatcher
    dp.add_handler(CommandHandler('bop', bop))
    updater.start_polling()
    updater.idle()


if __name__ == '__main__':
    main()

运行此代码后，我收到此错误。此外，在运行我编写的任何电报机器人后，我都会收到此错误。

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

    contents = requests.get('https://random.dog/woof.json').json()

    return request('get', url, params=params, **kwargs)

由于过滤，我还必须使用代理或 VPN 连接到电报。

我在回声机器人中遇到了另一个连接错误。我使用了电报机器人文档代码。我收到了这个错误：

raise MaxRetryError(_pool, url, error or ResponseError(cause))
urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='google', port=443): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x00000199A2C37DF0>: Failed to establish a new connection: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond'))
