I have code within a Flask application that uses JSONs in the request, and I can get the JSON object like so:
Request = request.get_json()
Changing the post to
response=self.app.post('/test_function',
data=json.dumps(dict(foo='bar')),
content_type='application/json')
fixed it.
Thanks to user3012759.
UPDATE: Since Flask 1.0 released flask.testing.FlaskClient
methods accepts json
argument and Response.get_json
method added, see example.
for Flask 0.x you may use receipt below:
from flask import Flask, Response as BaseResponse, json
from flask.testing import FlaskClient
from werkzeug.utils import cached_property
class Response(BaseResponse):
@cached_property
def json(self):
return json.loads(self.data)
class TestClient(FlaskClient):
def open(self, *args, **kwargs):
if 'json' in kwargs:
kwargs['data'] = json.dumps(kwargs.pop('json'))
kwargs['content_type'] = 'application/json'
return super(TestClient, self).open(*args, **kwargs)
app = Flask(__name__)
app.response_class = Response
app.test_client_class = TestClient
app.testing = True
