如何在Django中正確傳遞JSON

我正在爲我的Django應用程序中的視圖編寫測試。該視圖接受POST請求。它應該是JSON數據。我已經用Postman測試了它，但是當我嘗試在tests.py中傳遞它時不起作用，並且說JSON必須用雙引號引起來。事情是用雙引號。我究竟做錯了什麼？檢查下面的代碼。謝謝！如何在Django中正確傳遞JSON

views.py

"""This registration app-module generates views for register and auth pages.""" 

from json import loads 
from django.http import HttpResponse 
from django.contrib import auth 
from django.core.exceptions import ValidationError 
from django.core.validators import validate_email 

from .models import CustomUser 


def register(request): 
    """ 
    Registration method for CustomUser registration. 
    Args: 
     request: http request. 
    Returns: 
     If new user gets successfully registered - returns HttpResponse(201). 
     If not - returns HttpResponse(400). 
    """ 

    if request.method == 'POST': 
     data = loads(request.body.decode('utf-8')) 
     email = data["email"] 
     password = data["password"] 

     if CustomUser.get_by_email(email) is None: 
      try: 
       validate_email(email) 
       CustomUser.create(email, password) 
       return HttpResponse("User successfully created.", status=201) 
      except ValidationError: 
       return HttpResponse("This email is not valid format.", status=400) 
     return HttpResponse("This email is already registered.", status=400) 

    return HttpResponse(status=400)

tests.py

from django.test import TestCase 
from django.urls import reverse 

from registration.models import CustomUser 

class RegisterViewTests(TestCase): 
    """

              content_type='application/json') 
     self.assertEqual(response.status_code, 201)

您發佈當前不發佈JSON的方式，但表單字段值對。不知道這會起作用，但嘗試通過JSON作爲字符串，'self.client.post（reverse（'register_view'），'{「email」：「[email protected]」，「password」：「secret」 }'，content_type ='application/json'）' – janos

首先導入JSON'import json'，然後使用'json.dumps（{「email」：「[email protected]」，「password」：「secret」}） ' –

@RanjanChahan'json.dumps'。 –

@Rajan察罕的評論。在您的tests.py 中添加 import json在代碼的頂部。並修改代碼以這樣的：

class RegisterViewTests(TestCase): 
""" 
Test CustomUser model methods. 
""" 

def test_create(self): 
    """ 
    Test CustomUser.create(). 
    """ 

    response = self.client.post(reverse('register_view'), 
             json.dumps({"email": "[email protected]", "password": "secret"}), 
             content_type='application/json') 
    self.assertEqual(response.status_code, 201)

json.dumps還會變本加厲蟒蛇dict到json對象
