Python請求超時值錯誤

Question

晚上好，

我無法收到我的https請求。 我必須使用SSLv3，因此我要指定以下協議：

import requests
from requests.adapters import HTTPAdapter
from urllib3.poolmanager import PoolManager
import ssl

class MyAdapter(HTTPAdapter):
     def init_poolmanager(self, connections, maxsize, block=False):
        self.poolmanager = PoolManager(num_pools=connections,
                                        maxsize=maxsize,
                                        block=block,
                                        ssl_version=ssl.PROTOCOL_SSLv3)

username = 'username'
password = 'password'
email = 'email@example.com'
url = 'https://api.example.com/'
headers = {'Accept': 'application/json', 'content-type': 'application/json'}
params = {'emailaddress': email}
auth = (username, password)

s = requests.Session()
s.mount(url, MyAdapter())
r = s.get(url+'customer.svc/search', params=params, auth=auth, headers=headers)

當我運行get請求時，出現以下錯誤：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/ubuntu/workspace/app/venv/lib/python2.7/site-packages/requests/sessions.py", line 473, in get
    return self.request('GET', url, **kwargs)
  File "/home/ubuntu/workspace/app/venv/lib/python2.7/site-packages/requests/sessions.py", line 461, in request
    resp = self.send(prep, **send_kwargs)
  File "/home/ubuntu/workspace/app/venv/lib/python2.7/site-packages/requests/sessions.py", line 573, in send
    r = adapter.send(request, **kwargs)
  File "/home/ubuntu/workspace/app/venv/lib/python2.7/site-packages/requests/adapters.py", line 370, in send
    timeout=timeout
  File "/home/ubuntu/workspace/app/venv/lib/python2.7/site-packages/urllib3/connectionpool.py", line 517, in urlopen
    timeout_obj = self._get_timeout(timeout)
  File "/home/ubuntu/workspace/app/venv/lib/python2.7/site-packages/urllib3/connectionpool.py", line 283, in _get_timeout
    return Timeout.from_float(timeout)
  File "/home/ubuntu/workspace/app/venv/lib/python2.7/site-packages/urllib3/util/timeout.py", line 152, in from_float
    return Timeout(read=timeout, connect=timeout)
  File "/home/ubuntu/workspace/app/venv/lib/python2.7/site-packages/urllib3/util/timeout.py", line 95, in __init__
    self._connect = self._validate_timeout(connect, 'connect')
  File "/home/ubuntu/workspace/app/venv/lib/python2.7/site-packages/urllib3/util/timeout.py", line 125, in _validate_timeout
    "int or float." % (name, value))
ValueError: Timeout value connect was Timeout(connect=None, read=None, total=None), but it must be an int or float.

有任何想法嗎？ 我不知道。

附加上下文：我在一個Amazon EC2 Ubuntu實例上，運行請求2.5.1和python 2.7.6

當您引入外部urllib3發行版時，請求似乎並不總是很好。 我最終要做的是改為調用內部urllib3請求。

from requests.packages.urllib3.poolmanager import PoolManager

代替：

from urllib3.poolmanager import PoolManager

自從我開始這樣做以來沒有問題。
