Flask request and application/json content type

the request object already has a method get_json which can give you the json regardless of the content-type if you execute it with force=True so your code would be something like the following:

@menus.route('/', methods=["PUT", "POST"])
def new():
    return jsonify(request.get_json(force=True))

in fact, the flask documentation says that request.get_json should be used instead of request.json: http://flask.pocoo.org/docs/api/?highlight=json#flask.Request.json


Use request.get_json() and set force to True:

@menus.route('/', methods=["PUT", "POST"])
def new():
    return jsonify(request.get_json(force=True))

From the documentation:

By default this function will only load the json data if the mimetype is application/json but this can be overridden by the force parameter.

Parameters:

  • force – if set to True the mimetype is ignored.

For older Flask versions, < 0.10, if you want to be forgiving and allow for JSON, always, you can do the decode yourself, explicitly:

from flask import json

@menus.route('/', methods=["PUT", "POST"])
def new():
    return jsonify(json.loads(request.data))
