我发布到我的API以通过邮递员创建帐户
{
"email": "[email protected]",
"display_name": "outrageous canteloupe",
"password": "GramDaddyff!!5"
}
它有效，并且在数据库中注册了一个新帐户。
然后，我尝试通过Django测试发出相同的请求。
class AccountAPITestCase(TestCase):
def setUp(self):
pass
def test_create_account(self):
c = Client()
response = c.post('/accounts/', {
"email": "[email protected]",
"display_name": "outrageous canteloupe",
"password": "GramDaddyff!!5",
})
account = Account.objects.get(display_name='big_ouch')
self.assertTrue(account)
并且我收到以下错误。

我正在尝试以可重复的方式测试帐户的创建。我希望测试的行为与Postman相同。为什么它们的行为不同，如何纠正该错误？
您在使用序列化程序吗？可能是您的测试方法实际上没有推送JSON对象吗？尽管您的字符串看起来像一个JSON对象，但是Python需要知道它确实是一个JSON对象。看起来您的测试方法中可能存在一些冲突的数据。您的邮差员职位要求很干净。
您为什么仍然使用测试方法？如果您使用的是Django Rest Framework，则它具有内置的API测试页面，可以模仿Postman。
