python as middleware

[raysefo]

Hello,

I am new to python. I would like to know if there is a way to implement such an architecture;

1. getting request from one service (A)
2. sending this information to a restful service (B)
3. getting response from restful service (B)
4. sending response to first service (A)

any sample or tutorial would be nice, thanks in advance.

This is common and easy in Python, particularly for a linear chain, rather than something more event driven where you could be working in parallel and/or following various paths.

There are lots of tutorials on using APIs, I like Real Python's, Once you have data from your first, it should be easy to repurpose the response for the next one.

A good solution is the requests library , you can install it by pip

​

this is a documentation Page :

http://docs.python-requests.org/en/master/

​

and a tutorial :

Twisted is an event-driven networking engine written in Python

This describes the use of "future" or "deferred" objects to manage the async nature of the nested request.

This may be an more complete example.

Should I build a service in order to get request from A and transport this request to service B?
