How do I disable the security certificate check in Python's Requests?

I am using import requests requests.post(url='https://foo.example', data={'bar':'baz'}) but I get a request.exceptions.SSLError. The website has an expired certificate, but I am not sending sensitive data, so it doesn't matter to me. I would imagine there is an argument like 'verifiy=False' that I could use, but I can't seem to find it.
From the documentation: requests can also ignore verifying the SSL certificate if you set verify to False. >>> requests.get('https://kennethreitz.com', verify=False) <Response [200]> If you're using a third-party module and want to disable the checks, here's a context manager that monkey patches requests and changes it so that verify=False is the default and suppresses the warning. import warnings import contextlib import requests from urllib3.exceptions import InsecureRequestWarning old_merge_environment_settings = requests.Session.merge_environment_settings @contextlib.contextmanager def no_ssl_verification(): opened_adapters = set() def merge_environment_settings(self, url, proxies, stream, verify, cert): # Verification happens only once per connection so we need to close # all the opened adapters once we're done. Otherwise, the effects of # verify=False persist beyond the end of this context manager. opened_adapters.add(self.get_adapter(url)) settings = old_merge_environment_settings(self, url, proxies, stream, verify, cert) settings['verify'] = False return settings requests.Session.merge_environment_settings = merge_environment_settings try: with warnings.catch_warnings(): warnings.simplefilter('ignore', InsecureRequestWarning) yield finally: requests.Session.merge_environment_settings = old_merge_environment_settings for adapter in opened_adapters: try: adapter.close() except: pass Here's how you use it: with no_ssl_verification(): requests.get('https://wrong.host.badssl.example/') print('It works') requests.get('https://wrong.host.badssl.example/', verify=True) print('Even if you try to force it to') requests.get('https://wrong.host.badssl.example/', verify=False) print('It resets back') session = requests.Session() session.verify = True with no_ssl_verification(): session.get('https://wrong.host.badssl.example/', verify=True) print('Works even here') try: requests.get('https://wrong.host.badssl.example/') except requests.exceptions.SSLError: print('It breaks') try: session.get('https://wrong.host.badssl.example/') except requests.exceptions.SSLError: print('It breaks here again') Note that this code closes all open adapters that handled a patched request once you leave the context manager. This is because requests maintains a per-session connection pool and certificate validation happens only once per connection so unexpected things like this will happen: >>> import requests >>> session = requests.Session() >>> session.get('https://wrong.host.badssl.example/', verify=False) /usr/local/lib/python3.7/site-packages/urllib3/connectionpool.py:857: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised.
