How to read the server response?

Question

Python

I'm trying to parse the site, the page is generated from several requests to the server, one of them contains the necessary information in JSON.
I use selenium, scrapy, scrapy_splash.
How to get the server response from the request of interest?
If I separately generate the necessary request, the server rejects it.
Or monitor all requests (responses) on the page using the above solutions.

Answer 1

It's most likely the headlines. Show the site and tell me what info you want.

Answer 2

So maybe the question is how to send the request correctly?
