How do I run a set of code for all the requests in Flask

I want to run a set of code for every request that occurs in Flask, without adding extra lines of code for each view. Is there a way to write this code in a catch that can be applied before and after each view?

Hi,

You can use dedicated hooks(decorators) called before and after requests.

They are called:

Flask.before_request

Flask.after_request

@app.before_request
def do_something_whenever_a_request_comes_in():
    # request is available
@app.after_request
def do_something_whenever_a_request_has_been_handled(response):
    # we have a response to manipulate, always return one return response
