Tell me how you can parse phone numbers from the ULH or Avito . From what I found out, the OLH by clicking on the "show number" button sends a GET request to the server, with a token, but I don’t understand how the token is formed ... Is salt used in the form of time? Or is there some kind of algorithm? I flipped through all the js and html, but there is no token in the code anywhere. Or maybe you can somehow simulate a button click and parse the html that generates? If there are mechanisms implemented on Go, I will be very grateful for the example. I use goquery for parsing myself, can it be done through it?
