多方式登录
一、后台
1. 插件
pip install djangorestframework-jwt
2. urls.py
router = SimpleRouter()
router.register('', views.LoginAPIView, 'login')
urlpatterns = [
path('', include(router.urls)),
]
3. dev.py
import datetime
JWT_AUTH = {
'JWT_EXPIRATION_DELTA': datetime.timedelta(days=7),
}
4. vuews.py
from . import serializer
from luffyapi.utils.response import APIResponse
class LoginView(ViewSet):
# 用户登录接口视图
@action(methods=('POST',), detail=False)
def login(self, request, *args, **kwargs):
ser = serializer.Userserializers(data=request.data)
if ser.is_valid():
token = ser.context['token']
username = ser.context['user'].username
return APIResponse(token=token, username=username)
else:
return APIResponse(code=0, msg='Error', result=ser.errors)
5. serializers.py
class Userserializers(serializers.ModelSerializer):
# 提示: 因为继承了AbstractUser的表源码中username字段指定的是unique字段. 在视图中进行序列化data=request.data时, 如果不重定义
# 在序列化中就会被认为时存储数据, 因为data本质就是存储数据, 而我们这里因该重定义该字段, 去除这种影响
username = serializers.CharField()
class Meta:
model = models.User
fields = ['username', 'password', 'id']
extra_kwargs = {
'id': {'read_only': True},
'password': {'write_only': True}
}
# 多方式登录+签发token
def validate(self, attrs):
# 多方式登录
user = self._get_user(attrs)
# 签发token
token = self._get_token(user)
# 放在context中,以后在视图类中可以取出来使用
self.context['token'] = token
self.context['user'] = user
return attrs
# 多方式登录逻辑
def _get_user(self, attrs):
username = attrs.get('username')
password = attrs.get('password')
if re.match('^1[3-9][0-9]{9}$', username): # 判断用户使用的是电话号码的方式登录
user = models.User.objects.filter(telephone=username).first()
elif re.match('^.+@.+$', username): # 判断用户使用的是邮箱号的方式登录
user = models.User.objects.filter(email=username).first()
else: # 判断用户使用的是用户名的方式登录
user = models.User.objects.filter(username=username).first()
# 上面是判断用户是用哪种方式登录,下面是判断用户输入的密码是否正确
if user:
ret = user.check_password(password)
if ret:
return user
else:
raise ValidationError('密码错误!')
else:
raise ValidationError('当前用户不存在!')
# 签发token
def _get_token(self, user):
from rest_framework_jwt.serializers import jwt_payload_handler, jwt_encode_handler
payload = jwt_payload_handler(user)
token = jwt_encode_handler(payload)
return token
