我正在使用 Django Rest Frame Work，并且正在尝试使用会话中的令牌获取经过身份验证的用户信息
视图.py：
# Get Authenticated User Data
class UserAPIView(APIView):
authentication_classes = [JWTAuthentication]
permission_classes = [IsAuthenticated]
def get(self, request):
return Response(UserSerializer(request.user).data)
JWT身份验证
class JWTAuthentication(BaseAuthentication):
def authenticate(self, request):
token = request.COOKIES.get('jwt')
print('token = ', token)
if not token:
return None
try:
payload = jwt.decode(token, settings.SECRET_KEY, algorithms=['HS256'])
print('payload = ', payload)
except jwt.ExpiredSignatureError:
raise exceptions.AuthenticationFailed('unauthenticated')
user = User.objects.get(pk=payload['user_id'])
if not user:
raise exceptions.AuthenticationFailed('User not found!')
return (user, None)
@staticmethod
def generate_jwt(id):
payload = {
'user_id': id,
'exp': datetime.datetime.now() + datetime.timedelta(days=1),
'iat': datetime.datetime.utcnow()
}
return jwt.encode(payload, settings.SECRET_KEY, algorithm='HS256')
但我得到了这个错误
Invalid header padding
这是回溯

这是 Traceback 的其余部分
在处理上述异常的过程中，又出现了一个异常：
File "D:\Private\PythonProjects\ProCoders-02\src\Pepsi\profession\backend\blog\api\API_Authentication.py", line 20, in authenticate
payload = jwt.decode(token, settings.SECRET_KEY, algorithms=['HS256'])

payload, _, _, _ = self._load(jwt)
File "C:\Users\MAbbas\AppData\Local\Programs\Python\Python37\lib\site-packages\jwt\api_jws.py", line 188, in _load
raise DecodeError('Invalid header padding')
jwt.exceptions.DecodeError: Invalid header padding
修改 No.01（添加 LogInView 以显示我如何保存令牌）
登录查看
class LoginAPIView(APIView):
def post(self, request):
email = request.data['email']
password = request.data['password']
user = User.objects.filter(email=email).first()
if user is None:
raise exceptions.AuthenticationFailed('User not found!')
if not user.check_password(password):
raise exceptions.AuthenticationFailed('Incorrect Password!')
token = JWTAuthentication.generate_jwt(user.id)
response = Response()
response.set_cookie(key='jwt', value=token, httponly=True)
response.data = {
'message': 'success'
}
return response
如您所见，令牌存在于 cookie 中并打印出来，但这个错误让我很生气 提前致谢
