如何解决登录测试期间身份验证失败
我正在尝试测试自定义登录（使用 pytest），但身份验证失败返回 None。 这是views.py
(5,5),(21,14),(22,3),7)
serializers.py
from rest_framework.authtoken.views import ObtainAuthToken
from my_auth.api.serializers import UserLoginSerializer
class LoginAuthToken(ObtainAuthToken):
serializer_class = UserLoginSerializer
tests.py
from django.contrib.auth import authenticate
from django.utils.translation import gettext_lazy as _
from rest_framework import serializers
from rest_framework.authtoken.serializers import AuthTokenSerializer
class UserLoginSerializer(AuthTokenSerializer):
username = None
email = serializers.EmailField(
label=_("Email"),)
def validate(self,attrs):
email = attrs.get('email')
password = attrs.get('password')
if email and password:
user = authenticate(request=self.context.get('request'),email=email,password=password) # returns None
if not user:
msg = _('Unable to log in with provided credentials.')
raise serializers.ValidationError(msg,code='authorization') # raises
else:
msg = _('Must include "email" and "password".')
raise serializers.ValidationError(msg,code='authorization')
attrs['user'] = user
return attrs
终端输出：
import pytest
from django.urls import reverse
from rest_framework import status
from rest_framework.authtoken.models import Token
from rest_framework.test import APIClient
@pytest.fixture
def test_user():
user = MyUser.objects.create(
email='test@m.com',first_name='Firstname',last_name='Lastname'
)
user.set_password('pass5678')
return user
@pytest.mark.django_db
def test_login(test_user):
client = APIClient()
response = client.post(
path=reverse('login'),data={
'email': 'test@m.com','password': 'pass5678',},format='json',)
assert(response.status_code == status.HTTP_200_OK)
token = Token.objects.get(user=test_user)
assert(token.key == response.data['token'])
这是我在 test_login 中执行 ========================================================================================================== test session starts ==========================================================================================================

时的输出
print(response.data)起初我以为rest_framework.request.Request 对象没有传递给UserLoginSerializer 的validate()，但实际上它是。而且，它和我通过Postman发送POST请求时获得的Request几乎相同。我错过了什么？
解决方法
您仍然需要在调用 save 后调用 set_password 用户：
@pytest.fixture
def test_user():
user = MyUser.objects.create(
email='test@m.com',first_name='Firstname',last_name='Lastname'
)
user.set_password('pass5678')
user.save()
return user
https://docs.djangoproject.com/en/3.2/ref/contrib/auth/#django.contrib.auth.models.User.set_password
将用户的密码设置为给定的原始字符串，处理密码散列。不保存 User 对象。
