pycurl https error: unable to get local issuer certificate
pycurl, python, ssl, ssl-certificate, windows
Solution
The problem is that `pycurl` needs an up-to-date certificate chain to verify the ssl certificates.
A good solution would be to use certifi.
It's basically an up-to-date copy of mozilla's built in certificate chain wrapped in a python package which can be kept up to date using pip. `certifi.where()` gives you the location to the certificate bundle.
To make `pycurl` to use it, set the `CAINFO` option:
import pycurl
import certifi
curl = pycurl.Curl()
curl.setopt(pycurl.CAINFO, certifi.where())
curl.setopt(pycurl.URL, 'https://www.quora.com')
curl.perform()
Problem
``` >>> import pycurl >>> c = pycurl.Curl() >>> c.setopt(c.URL, 'https://quora.com') >>> c.perform() Traceback (most recent call last): File "<stdin>", line 1, in <module> pycurl.error: (60, 'SSL certificate problem: unable to get local issuer certificate') >>> >>> c.setopt(c.URL, 'http://quora.com') >>> c.perform() >>> >>> ``` Why is it unable to get local issuer certificate? How do I solve this? When I open quora.com in my browser, I see that its identity is verified. Why is this the case? How do I get pycurl to use the same certificates my browser uses?
