PythonAnywhere ConnectionRefusedError：[Errno 111] 與 Twilio 一起使用時連接被拒絕

Question

我正在使用 PythonAnywhere 來運行一個簡單的腳本。 這是一次試驗，我寫了一個腳本，每小時給我發送一條短信。 但是每次我運行我的腳本時，它都會顯示一個錯誤。

我的腳本是：

from twilio.rest import TwilioRestClient
from time import sleep

client = TwilioRestClient('AC******************', '**********************')

while True:
    client.messages.create(
        to="+1123456789",
        from_="+1987654321",
        body="Trial.",
    )
    print('Message Sent!')
    sleep(3600)

錯誤是：

    body="Trial.",

我一直無法找到解決此問題的方法。 我向您保證，與 Twilio 相關的詳細信息是正確的。 這是 PythonAnywhere 安全錯誤。 請告訴我如何克服這個問題。

Answer 1

PythonAnywhere 開發人員：經過反復反復，我們終於解決了這個問題——Twilio 客戶端庫所依賴的 httplib2 庫似乎忽略了 Python 3.x 的代理設置。

解決方案是使用 Python 2.7。
