flask abort as json

flask_abort_example.py

from flask import abort, make_response, jsonify
abort(make_response(jsonify(message="Message goes here"), 400))

From the docs, it wasn't obvious that flask.abort accepted also a flask.Response, very helpful, thx!

Also you could do just

abort(jsonify(message="Message goes here"))

WWWWWWWWWWWWWWWWWWWWWOW

Also you could do just

abort(jsonify(message="Message goes here"))

This is it 🚀

@tamirOK in decorators you want to raise errors in some cases and not to return

Notice that

abort(jsonify(message="Message goes here"))

returns 200 status code.

THANK YOU THIS SAVED MY LIFE.

I was sooo frustrated. My solution is this:

abort(make_response(jsonify(errors=['Your input sucks', 'our service is down', 'Google is being slow suck it']), status, HEADERS))

thank you!

This is goofy, because jsonify already returns a Response, but then you have to wrap it in another one just to set the status code. Why is abort this bad this many years on?

I'm doing abort(Response(f'{{["error":{str(ex)}}}\n'], status=400, content_type='application/json')) instead, because I regard it to be less of a hack. But really jsonify should have a parameter that allows you to set the status.

@pavelkomarov You can return specific status with jsonify by returning a tuple like this for example:

return jsonify({"error": "Unauthorized"}), 401

If you have your API code in a blueprint, you can also do this I believe

@blueprint_api.errorhandler(404)
def not_found(error):
    return make_response(jsonify({'error': 'Sorry, board not found'}), 404)

The good thing here is that any other requests outside of the blueprint will continue to see the normal 404 page
