GET/POST request with additional non named parameter using python requests

you can create a function and replace the params.

For example:

def request_function(host, param, value, user, passwd):
    try:
        host = f'http://{host}?{param}={value},{user}{password}'
        response = requests.get(host)
        return [True, response.status_code, response.text]
    except:
        try:
            host = f'http://{host}?{param}={value}&{user}{password}'
            response = requests.get(host)
            return [True, response.status_code, response.text]
        except:
            try:
                host = f'http://{host}?{param}&{user}{password}'
                response = requests.get(host)
                return [True, response.status_code, response.text]
            except:
                return [False, 0, 'No works']

Depend which works , you can delete others try block.

It needed a little bit fiddling around, but now I found a solution by myself. The clue was to recognize that a request can be prepared and that the so called PreparedRequest is fully mutable as stated in the manual https://requests.readthedocs.io/en/latest/api/#requests.PreparedRequest (followed by a usage example):

class requests.PreparedRequest

The fully mutable PreparedRequest object, containing the exact bytes that will be sent to the server. [...]

So, when they claim that it's fully mutable I should be able to condition the PreparedRequest for my needs.

This is shown in the following code, which makes two different requests to the anel outlet. It first generates a Request object and then prepares it, resulting in a PreparatedRequest instance. In the prepared request the url is modified stripping some placeholders for positional only parameters. Then the modified request is sent to the outlet.

The additional code needs effectively 7 LLOCs, which should be reasonable in most cases. The rest is just testcode and code for debugging output. The given user and pass is the factory default in this example and would need to be replaced by the actual user and pass.

import requests
from requests import session, Request


BASE_URL = "http://192.168.0.245"


def request_hack(url: str = BASE_URL, params: dict = None) -> requests.PreparedRequest:
    DUMMY = "dummy"

    if isinstance(params, dict):
        # The requests lib would normally ignore params mapping to None,
        # but if we replace the None values using some DUMMY the resulting
        # url can be conditioned to strip the superfluous assignments in
        # the positional only parameters
        params = {k: v or DUMMY for k, v in params.items()}

    # The request cannot be sent directly as the URL syntax for the anel outlets is not supported by the requests lib
    # Therefore, we first set-up a PreparedRequest and then modify the url to our needs
    req = Request("GET", url, params=params).prepare()
    print(f"Unconditioned request {req.url}")
    # Remove the DUMMY values and the preceeding equal signs by replacing them with empty strings
    req.url = req.url.replace(f"={DUMMY}", "")
    print(f"Conditioned request {req.url}")

    return req


if __name__ == "__main__":
    the_session = session()


    """ Perform a Stat request to the anel outlet """
    req = request_hack(params={"Stat": None, "adminanel": None})
    res = the_session.send(req)
    print(res.text)

    """ Perform a Switch request to the anel outlet """
    req = request_hack(params={"Sw": "0x55", "adminanel": None})
    res = the_session.send(req)
    print(res.text)

The sample code would output something like:

Unconditioned request http://192.168.0.245/?Stat=dummy&adminanel=dummy
