JSON-Dekodierfehler beim Senden der Postanforderung während des Testens

Question

Ich versuche meine Anmelde-URL zu testen. Wenn ich folgendes mache, gibt es einen Fehler.

tests.py

from __future__ import unicode_literals 
from django.test import TestCase 
# Create your tests here. 
class SignUpTest(TestCase): 
    def test_createAccount(self): 
     import pdb; pdb.set_trace() 
     response = self.client.post('/signup/', {'username': 'test_username', 'password': 'test_password',"email":"example@gmail.com", "confirm_password":"test_password", "type_of_user":"1", "first_name":"john", "last_name":"doe"}) 
     print response 
     self.assertIs(response, {"success":True}) 

Es gibt mir die folgende Fehlermeldung:

Das ist mein urls.py

from django.conf.urls import url 
from django.contrib import admin 
from portal.views import * 
urlpatterns = [ 
    url(r'^admin/', admin.site.urls), 
    url(r'^signup/',signup,name='signup'), 
    url(r'^addproduct/',addProduct,name='addproduct'), 
    url(r'^logout/',logout,name='logout'), 
    url(r'^login/',login,name='login'), 
    url(r'^deleteproduct/',deleteProduct,name='deleteproduct'), 
    url(r'^search/',search,name='search'), 
    url(r'^update/',update,name='update'), 
    url(r'^getproduct/',getProduct,name='getproduct'), 
] 

Das ist mein views.py

ist

@csrf_exempt 
def signup(request): 
    if request.method=='POST': 
     data = request.body 
     data = json.loads(data) 
     username = data["username"] 
     email = data["email"] 
     password = data["password"] 
     confirm_password = data["confirm_password"] 
     first_name = data["first_name"] 
     last_name = data["last_name"] 
     type_of_user = data["type_of_user"] 

     if password!=confirm_password: 
      return JsonResponse({"success":False,"reason":"passwords don't match"}) 
     user = User(username=username,email=email,first_name=first_name,last_name=last_name) 
     user.set_password(password) 
     user.is_active=True 
     try: 
      user.save() 
     except: 
      return JsonResponse({"success":False,"reason":"user already exists"}) 

     user_a=authenticate(username=username,password=password) 
     if user_a is not None: 
      if user_a.is_active: 
       log(request,user_a) 
     else: 
      return HttpResponse({"success":False,"reason":"internal db error"}); 

     access_token = str(uuid.uuid4().get_hex()) 
     try: 
      # import pdb; pdb.set_trace() 
      at = AccessToken(token_value=access_token) 
      at.save() 
      UserProfile(user=user,type_of_user=int(type_of_user),access_token=at).save() 
     except: 
      return JsonResponse({"success":False,"reason":"internal error"}) 
     return JsonResponse({"success":True,"access_token":access_token}) 

P.S Ich habe versucht mit json.loads und json.dump und versuchte auch mit doppelten Anführungszeichen anstelle von einfachen Anführungszeichen. Es funktioniert nicht.

Answer 1

Der Fehler kommt von der Anmeldeansicht in Zeile data = json.loads(data). Um die POST Daten zugreifen, die Sie einfach request.POST unter Verwendung von zugreifen können:

data = request.POST 

Also diese Zeilen entfernen und mit über Codezeile ersetzen:

data = request.body 
data = json.loads(data) 

Oder versuchen (wie über heraus Diskussion):

response = self.client.post('/signup/', json.dumps(my_data), content_type='application/json')
