How to Disable Certificate Verification in Python Requests?

Disable Certificate Verification in Python Requests

When encountering an expired certificate error while making HTTPS requests with requests, a common solution is to disable the security certificate check.

Solution 1: Using verify=False

As mentioned in the documentation, you can pass verify=False to disable certificate verification.

<code class="python">import requests
requests.post(url='https://foo.example', data={'bar':'baz'}, verify=False)</code>

Copy after login

Solution 2: Monkey Patching requests (Context Manager)

For more advanced usage, you can use a context manager to monkey patch requests and disable certificate verification for all requests within the context.

<code class="python">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):
        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</code>

Copy after login

Usage:

<code class="python">with no_ssl_verification():
    requests.get('https://wrong.host.badssl.example/')</code>

Copy after login

Note that this context manager closes all open adapters after leaving it to avoid unexpected behavior due to cached connections.
