테스트 중에 게시 요청을 보내는 동안 JSON 디코딩 오류가 발생했습니다.

Question

가입 URL을 테스트하려고합니다. 다음과 같이하면 오류가 발생합니다.

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}) 

그것은 나에게 다음과 같은 오류 제공 : 이것은 내 urls.py입니다

     return JsonResponse({"success":True,"access_token":access_token}) 

P.S json.loads 및 json.dump을 사용해 보았으며 작은 따옴표 대신 큰 따옴표를 사용해 보았습니다. 그것은 작동하지 않습니다.

Answer 1

data = json.loads(data)의 가입보기에서 오류가 발생했습니다.

data = request.POST 

그래서이 라인을 제거하고 코드 위의 라인을 교체 :

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

을 또는 통해 파악로 (시도 단순히 request.POST를 사용하여 액세스 할 수 POST 데이터에 액세스하기 위해 토론) :

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