Disable ssl verification on a third party module using HTTPX

Question

I’m using a module that uses httpx to make a request. Because of my company’s network policy, I get a CERTIFICATE_VERIFY_FAILED every time I try to run my code. The data I’m sending and receiving in the request is not sensitive so I want to disable the SSL verification on the module.

If I were to write the request I could use a session as such:

client = httpx.Client(**kwargs, verify=False)

But the request is inside the module.

Blender did an excellent response on this stack overflow answer where they wrote a context manager with the code bellow but the code does not work for the httpx module:

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

Is there a way I could replicate the same behavior inside a request made through httpx?

Works when module uses httpx.Client:

import contextlib


@contextlib.contextmanager
def no_ssl_verification():
    """Context manager to disable SSL verification on httpx Client.
    """
    import httpx

    # Save original Client constructor
    Client = httpx.Client

    # Disable SSL verification
    httpx.Client = lambda *args, **kwargs: Client(*args, verify=False, **kwargs)

    # Yield control to the caller
    yield

    # Restore original verify value
    httpx.Client = Client
