Authorization using POST request?

Question

Web servers

Good afternoon,
We have a web table with IP addresses from Eltex switches.
To speed up / simplify access to the Web-interface of the switch, when you click on the button, you would immediately fall into the Web-interface of the switch.
As I understand it, authorization occurs through a POST request.

Request URL: http://10.26.6.2/config/log_off_page.htm
Request Method: POST
Status Code: 302 Redirect
Remote Address: 10.26.6.2:80
Referrer Policy: no-referrer-when-downgrade

How to organize a request for access?))

Answer 1

Make a post request on the backend (php, nodejs, java, ...) and return the result to the frontend. You can test with curl first.
PHP example:

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://адрес_странички");
curl_setopt($ch, CURLOPT_POST, 1);
curl_exec ($ch);
curl_close ($ch);
