Warum auf flaschen unruhig == 1.0.0b1 Ergebnis in ERROR meine POST-Anfragen tut: 400 Fehlende Werte

Question

ich den folgenden Code haben:

import requests 
data = {u"username":u"cryarchy", u"password":u"Pass1234", u"email":u"email@domain.com"} 
url = "http://localhost:5000/api/account" 
headers = {"Content-Type":"application/vnd.api+json", "Accept":"application/vnd.api+json"} 
import json 
r = requests.post(url, data=json.dumps(data), headers=headers) 

nach der Anforderung, zeigt der Kolben-Debug-Konsole die folgenden:

127.0.0.1 - - [02/Jun/2016 08:33:03] "POST /api/account HTTP/1.1" 400 - 
{u'username': u'cryarchy', u'password': u'Pass1234', u'email': u'email@domain.com'} 
-------------------------------------------------------------------------------- 
ERROR in base [/home/user/tizy/MyFlask/e2-papers/venv/local/lib/python2.7/site-packages/flask_restless/views/base.py:726]:

MissingData 
127.0.0.1 - - [02/Jun/2016 08:33:11] "POST /api/account HTTP/1.1" 400 - 

die Daten auf dem Debug-Fenster gedruckt wird immer, weil ich die folgende POST Präprozessor haben:

def post_vars_init(data=None): 
    if (not data): 
     raise ProcessingException(description="No data", code=500) 
    print(data) 

Answer 1

bemerkte meinen Fehler nach einem erneuten Besuch zu https://flask-restless.readthedocs.io/en/1.0.0b1/creating.html. Das Post-Anfrage-Datenformat ist, was ich falsch verstanden hatte. Es sollte sein:

data = {'data': {'attributes': {u'username': u'cryarchy', u'password': u'Pass1234', u'email': u'email@domain.com'}, 'type': 'account'}}
