Python请求代理连接超时

Question

我正在使用此代码来检查代理服务器：

def check_proxy(p):
    try:
        r = requests.get('https://httpbin.org/get', proxies={'https': 'https://%s' % p}, timeout=5)
        if r.status_code == 200:
            return True
        else:
            return False
    except:
        return False

它与工作代理一起工作得很好。几分钟后，由于代理错误而失败：

Traceback (most recent call last):
  File "/home/me/Desktop/general/test_proxyt.py", line 22, in check_proxy
    r = requests.get('https://httpbin.org/get', proxies={'https': 'https://%s' % p}, timeout=5)
  File "/usr/local/lib/python2.7/dist-packages/requests/api.py", line 59, in get
    return request('get', url, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/requests/api.py", line 48, in request
    return session.request(method=method, url=url, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/requests/sessions.py", line 451, in request
    resp = self.send(prep, **send_kwargs)
  File "/usr/local/lib/python2.7/dist-packages/requests/sessions.py", line 557, in send
    r = adapter.send(request, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/requests/adapters.py", line 413, in send
    raise ConnectionError(e, request=request)
ConnectionError: HTTPSConnectionPool(host='httpbin.org', port=443): Max retries exceeded with url: /get (Caused by ProxyError('Cannot connect to proxy.', error(110, 'Connection timed out')))

是否可以设置代理连接超时异常？

Answer 1

也许你可以尝试模块附带的

exceptions

。

def check_proxy(p):
    try:
            r = requests.get('https://httpbin.org/get', proxies={'https': 'https://%s' % p}, timeout=5)
            if r.status_code == 200:

                return True
            else:
                return False
    except requests.exceptions.Timeout as e:

        # Maybe set up for a retry
        print e

    except requests.exceptions.RequestException as e:
        print e

在此结束循环，这是请求中的一个错误，此后已通过更新到 urllib3 来修复
