Flask - 在after_request或teardown_request中访问请求

Question

I want to be able to access the request object before I return the response of the HTTP call. I want access to the request via "teardown_request" and "after_request":

from flask import Flask
...
app = Flask(__name__, instance_relative_config=True)
...

@app.before_request
def before_request():
    # do something

@app.after_request
def after_request(response):
    # get the request object somehow
    do_something_based_on_the_request_endpoint(request)

@app.teardown_request
def teardown_request(response):
    # get the request object somehow
    do_something_based_on_the_request_endpoint(request)

I saw that I can add the request to g and do something like this:

g.curr_request = request

@app.after_request
def after_request(response):
    # get the request object somehow
    do_something_based_on_the_request_endpoint(g.curr_request)

But the above seems a bit strange. I'm sure that there's a better way to access the request.

Thanks

Answer 1

The solution is simple -

from flask import request

@app.after_request
def after_request(response):
    do_something_based_on_the_request_endpoint(request)
    return response

Also try teardown_request(exception). This executes "regardless of whether there was an exception or not". Check the documentation: http://flask.pocoo.org/docs/0.12/api/#flask.Flask.teardown_request
