import requests gives SSL error in datadog client

[leetemil]

Describe the bug
If the line import requests is added to the code example for service checks, I get an SSL error from the datadog api client.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://docs.datadoghq.com/api/latest/service-checks/
2. Run the python code example and see that it indeed works with response {'status': 'ok'}
3. Add import requests to that code example.
4. See error, with traceback ending with something as follows

urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='api.datadoghq.eu', port=443): Max retries exceeded with url: /api/v1/check_run (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')])")))

Expected behavior
The import of requests should cause no change in behavior.

Hi,

It looks more an issue with pyOpenSSL than requests. Can you upgrade requests to at least 2.24.0? It seems to work starting that version.

It works by upgrading. I also made it work with the workaround in #812 for those with older versions of requests. Thanks for taking a look @therve

No problem! For the record, the issue comes from the inject_into_urllib3 call which was removed in psf/requests#5443 (and is not recommended).

But if you're stuck with that version of requests (or want to use pyOpenSSL for some reasons), you can fix it by pass the CA certs directly, eg:

from datadog_api_client.v1 import Configuration
import certifi

configuration = Configuration(ssl_ca_cert=certifi.where())
