The documentation says to use request.get_json(), but that causes the service to return an error:
Server returned HTTP response code: 500
calling request.data or request.json both work, however.

I thought get_json is was the preferred way to get the json data.

get_json. Parses the incoming JSON request data and returns it. By default this function will return None if the mimetype is not application/json but this can be overridden by the force parameter.
from flask import Flask from flask import request app = Flask(__name__) @app. route('/users/<user_id>', methods = ['GET', 'POST', 'DELETE']) def user(user_id): if request. method == 'GET': """return the information for <user_id>""" . . . if request.
from flask import request @app.route('/') def index(): username = request.cookies.get('username') # use cookies.get(key) instead of cookies[key] to not get a # KeyError if the cookie is missing. Note that cookies are set on response objects.
In Flask/wrappers.py the method get_json() is defined as method to the class Request.
However, the same file still contains the old, deprecated method json(). If you have an old version of flask, then a) update or b) use request.json() instead.

I had similar error with the flask Response object, it ended up being a version issue, we used flask 0.12.1 and get_json() is available on 1.0.2
