Record http request and response

I want to create a Mock server from my existing python server to be able to develop the client locally.

Is there a way to record all the traffic from a web-site automatically including body response and requests?

I've tried to use postman inspect tool, but I need to resend every request after I've inspected the request to get the response and I have more than 300 http requests. Ideally I would like to browser through my website dump all the responses and requests to a file and create a mock server based on that.
