configure connexion to gzip its responses?

[drafter250]

Description

I have a client that expects all api responses to be gzipped.

simply adding "Content-Encoding": "gzip" to response headers doesn't actually signal flask or connexion to gzip the response.

apparently this is usually left up to the production webserver like nginx.

I also tried installing flask-compress to modify the app instance to gzip it's responses automatically. but got various errors about missing attributes.

Expected behaviour

For Testing is there a relatively simple way to get connexion to gzip its responses?

Actual behaviour

Steps to reproduce

Additional info:

Output of the commands:

• python --version 3.6.5
• pip show connexion | grep "^Version\:"

Can you post a snippet on how you tried to use flask-compress? Please note that for flask extensions you need usually need to use app.app since they expect a Flask App not a Connexion one.

Yup!
If you are deploying a connexion app to production, you will want to use a production webserver like nginx anyway - the built-in flask webserver is for development only!.
If you want to test gzip (or other nginx features) I'd recommend doing this in an integration test against your packaged (app + nginx/gunicorn).
I don't recommend trying to add this features to the development server.
