![]() ![]() In situations, where you're using a library and have no control over the ca-bundle location you could also explicitly set the ca-bundle location to be your host-wide ca-bundle: REQUESTS_CA_BUNDLE=/etc/ssl/certs/ca-bundle.crt python -c "import requests requests.get('')" especially the fact that you do not seem to use the system ca store first and this is not documented anywhere. ![]() bundling your own cacerts with request is really, really annoying. usr/local/lib/python2.7/dist-packages/requests/cacert.pemītw. # (py2.7.10, verify python -c "import requests print ()" usr/lib/python2.7/dist-packages/certifi/cacert.pem Linux # (py2.7.5,requests 2.7.0, verify not python -c "import requests print ()" Windows C:\>python -c "import requests print ()"Ĭ:\Python27\lib\site-packages\requests-2.8.1-py2.7.egg\requests\cacert.pem Here's a generic approach to find the cacert.pem location: In case you have a library that relies on requests and you cannot modify the verify path (like with pyvmomi) then you'll have to find the cacert.pem bundled with requests and append your CA there. Path to a CA_BUNDLE file for Requests to use to validate the certificates.Īlso take a look at the cert parameter on the same link.False: bypasses certificate validation completely.True: causes the certificate to validated against the library's own trusted certificate authorities (Note: you can see which Root Certificates Requests uses via the Certifi library, a trust database of RCs extracted from Requests: Certifi - Trust Database for Humans).So, as of version 2.0, the verify parameter accepts the following values, with their respective semantics: pem file of the certificate (which you should obtain by some sort of secure means). If just skipping the certificate check is not acceptable in your particular context, consider the following options, your best option is to set the verify parameter to a string that is the path of the. As mentioned in the comments, this may be acceptable for quick/throwaway applications/scripts, but really should not go to production software. This will expose your application to security risks, such as man-in-the-middle attacks. Please note that this will cause the certificate not to be verified. Like mentioned in a previous comment, the quickest fix is setting verify=False: requests.get('', verify=False) The problem you are having is caused by an untrusted SSL certificate. : _ssl.c:503: error:14090086:SSL routines:SS元_GET_SERVER_CERTIFICATE:certificate verify failed Response = requests.get(url1, headers=headers)įile "build/bdist.linux-x86_64/egg/requests/api.py", line 52, in getįile "build/bdist.linux-x86_64/egg/requests/api.py", line 40, in requestįile "build/bdist.linux-x86_64/egg/requests/sessions.py", line 209, in requestįile "build/bdist.linux-x86_64/egg/requests/models.py", line 624, in sendįile "build/bdist.linux-x86_64/egg/requests/models.py", line 300, in _build_responseįile "build/bdist.linux-x86_64/egg/requests/models.py", line 611, in send I don't know what Python requests is wanting? Where is this SSL certificate supposed to reside? Traceback (most recent call last): I would like to use Kenneth Reitz's python requests because it's a great piece of work! However, CAS requires getting validated via SSL so I have to get past that step first. I'm working on a simple script that involves CAS, jspring security check, redirection, etc. ![]()
