Question

我正在尝试异常处理这些代理错误，我正在尝试关注但没有成功：

from requests.exceptions import ProxyError, SSLError, ConnectionError

def adding(self):

    headers={
      'User-Agent':'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.167 Safari/537.36'
    }

    url = 'url'

    r = self.session.get(url, headers=headers)

def run(self):
    while True:
          try:
              self.adding()
          except OSError as e:
          print 'OSError'

          except ProxyError as g:
          print 'ProxyError'

然而，当我运行python脚本时，我仍然在日志中出错：

您的例外下方的print语句不会缩进为其各自except语句的一部分，而您的try似乎没有正确缩进。我不确定这是否能解决你的问题，但它似乎是无意的。

异常处理ProxyError，Python中的OSError
