Python-问题SSL：CERTIFICATE_VERIFY_FAILED

Question

I'm trying to solve the problem

requests.exceptions.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:579)

when I connect to a handle server.

I also used

ssl._create_default_https_context = ssl._create_unverified_context

as some user suggested, but I'm not able to fix the issue.

Any other solution?

Thanks

Does your server have a valid certificate, signed by a Certification Authority?

If it uses a self-signed certificate I would suggest that you save a copy of the public certificate in your Python project and pass the certificate name in the verify parameter on requests.

You can save the certificate by accessing the server on Firefox, clicking on the Lock icon near to the address bar, selecting the Certificate, then More details, then View Certificate, then export.

You will get a .pem file, let's say: "my_server_certificate.pem".

Then when you create your Session object on requests you can pass the parameter:

session = requests.Session()
session.verify = "my_server_certificate.pem"

I had similar problems when using charles proxy with my Python scripts. I hope this helps you solve your problem as well.
