python - Pythonanywhere 上的 "[Errno 111] Connection refused"

Question

我正在尝试在 pythonanywhere 上部署我的应用程序，但我无法连接到 Twitter。

这是我得到的错误:-

Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1687, in wsgi_app

self.timeout, self.source_address)
File "/usr/lib/python2.7/socket.py", line 571, in create_connection
raise err
IOError: [Errno socket error] [Errno 111] Connection refused

我尝试运行的代码是这样的:-

proxies = {'http': 'http://proxy.server:3128'}
connection = urllib.urlopen(url, proxies=proxies)
data = connection.read()

我正在尝试访问以下 URL :- ' https://api.twitter.com/1.1/application/rate_limit_status.json '

我在 pythonanywhere 上有一个免费帐户，并验证了 AP​​I 已列入白名单，并且我正在使用他们在此处描述的代理(http://help.pythonanywhere.com/pages/403ForbiddenError)。

将我的评论复制到正确的答案:让代理与 urllib 一起工作可能很棘手。 requests 通常更易于使用，它从环境变量中提取代理设置。绝对推荐!
