Recently I once again stumbled upon a detail of the HTTP specification involving the POST verb and "enforced" https. I'll document it here in an attempt to save other people the time (hopefully also future-me). Do you want to know more?
Flask pretty-prints response generated by the
flask.json.jsonifyfunction. Avoiding this on a per request basis doesn't seem to be intended: There is a configuration variable for the whole application:
JSONIFY_PRETTYPRINT_REGULAR. But setting that to
Falseminifies every JSON responses. And, in general, I enjoyed the pretty printed output. So implementing
X-PrettyPrint- which seems to be a quasi-standard - also sounded like a the wrong way because it means replacing the call to
jsonifyby a custom implementation. This short story has a happy end though: Flask does not pretty-print the response if it receives an AJAX request. So one can just send the appropriate header:
curl -H 'X-Requested-With: XMLHttpRequest' "https://exmaple.com/api/endpoint.json";
