suppressing insecure requests warnings in python: a comprehensive tutorial

python's `requests` library, a staple for http interactions, throws warnings when making requests to insecure http sites (sites using the http protocol instead of the more secure https). these warnings are crucial for security, highlighting potential vulnerabilities to man-in-the-middle attacks. however, in specific controlled environments or for legacy systems, suppressing these warnings might be necessary. this tutorial details how to handle insecure request warnings effectively, emphasizing best practices and cautionary notes. we will not advocate disabling warnings indiscriminately; rather, we’ll focus on situations where managed suppression is justifiable.

*understanding the warning*

when you use `requests` to connect to an http url, you'll see a warning similar to this:



this warning stems from `urllib3`, a dependency of `requests`. it signifies that the request is proceeding without verifying the server's ssl/tls certificate. this lack of verification makes your communication vulnerable.

*methods for suppressing insecure request warnings*

several approaches exist to manage these warnings, each with its implications:

*1. using `requests.packages.urllib3.disable_warnings()` (least recommended):*

this is the most straightforward but also the least recommended method. it globally disables all `insecurerequestwarning`s, potentially masking other critical security issues in your code.



*why it's discouraged:* this approach is highly risky. it hides warnings for all insecure requests, potentially leaving you vulnerable without knowing it. use this only as a last resort and only if you completely understand the security implications and have other mechanisms in place to ensure security (like a dedicated vpn or other security layers).

*2. using a custom `urllib3` context (recommended for controlled environments):*

this method allows you to suppress warnings fo ...
