Question

Traceback (most recent call last):
  File "C:\Python27\Scripts\Vehicle Model.py", line 12, in <module>
    response = requests.get(URL_PATTERN1)
  File "C:\Python27\lib\site-packages\requests-2.7.0-py2.7.egg\requests\api.py", line 69, in get
    return request('get', url, params=params, **kwargs)
  File "C:\Python27\lib\site-packages\requests-2.7.0-py2.7.egg\requests\api.py", line 50, in request

    raise SSLError(e, request=request)
SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)

编译完代码后出现上述错误。我目前正在使用Edmunds API从其API中提取特定项目。当我在其他计算机上编译时，我不知道为什么我没有收到此错误消息。

然后当我添加：

context = ssl._create_unverified_context()
urllib2.urlopen("https://no-valid-cert", context=context)

我收到以下错误：

Traceback (most recent call last):
  File "C:\Python27\Scripts\Vehicle Model.py", line 10, in <module>
    urllib2.urlopen("https://no-valid-cert", context=context)
  File "C:\Python27\lib\urllib2.py", line 154, in urlopen
    return opener.open(url, data, timeout)
  File "C:\Python27\lib\urllib2.py", line 431, in open
    response = self._open(req, data)
  File "C:\Python27\lib\urllib2.py", line 449, in _open
    '_open', req)
  File "C:\Python27\lib\urllib2.py", line 409, in _call_chain
    result = func(*args)

    raise URLError(err)
URLError: <urlopen error [Errno 11004] getaddrinfo failed>

您应首先使用curl验证是否已正确设置所有内容。以下是我将使用的步骤：

curl --version
curl -v https://api.edmunds.com/
# this latter should verify that SSL and libcurl are working properly on the computer

如果这两个都有效，那么请求也应该有效。如果您想在不验证SSL的情况下使用请求，可以使用get参数session.get('https://api.edmunds.com/', verify=False)。
