SSLError Certificate Verify Failed Python API

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

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

I get the above error after compiling my code. I am currently using Edmunds API to extract specific items from their API. I don't know why I don't get this error message when I compile on other computers.

Then when I add:

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

I get the following error:

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)

    raise URLError(err)

You should first verify that everything is set up correctly with curl. Here are the steps I would use:

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

If both of those work, then requests should also work. If you want to use requests without verifying SSL, you can use the verify parameter to get.

session.get('https://api.edmunds.com/', verify=False)
