Django Rest Framework中的JWT身份验证错误“无效签名”

提问于

我_1661560_尝试使用JWT（http://getblimp.github.io/django-rest-framework-jwt/）配置身份验证 . 当我尝试通过我的api进行身份验证时，我收到了"Invalid Signature"错误 . 我在https://jwt.io/确认了错误 . 这似乎意味着我的令牌正在被不正确地创建 . 有任何想法吗？

这是我的配置：

from django.db import models

class User(models.Model):
    first_name = models.CharField(max_length=45)
    last_name = models.CharField(max_length=45)
    username = models.CharField(max_length=45, unique=True)
    phone = models.CharField(max_length=20)
    password = models.CharField(max_length=100, blank=False, default='')

from rest_framework import serializers
from . models import User
from django.contrib.auth.hashers import make_password

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ('id', 'first_name', 'last_name', 'username', 'phone', 
'password')
    extra_kwargs = {'password': {'write_only': True}}
    def create(self, validated_data):
        # the create method creates and saves an object in a single statement
        user = User.objects.create(
            first_name = validated_data['first_name'],
            last_name = validated_data['last_name'],
            username = validated_data['username'],
            phone = validated_data['phone'],
            password = make_password(validated_data['password']),
        )

        return user

from joyrides_api.models import User
from joyrides_api.serializers import UserSerializer
from rest_framework.response import Response
from rest_framework.views import APIView
from rest_framework import status
from rest_framework_jwt.utils import jwt_payload_handler
from rest_framework import permissions
from rest_framework_jwt.settings import api_settings
from rest_framework.permissions import AllowAny
from rest_framework_jwt.authentication import JSONWebTokenAuthentication

class UserList(APIView):

    permission_classes = (AllowAny,)
    # this method creates the user
    def post(self, request, format=None):
            serializer = UserSerializer(data=request.data)
            if serializer.is_valid():
                # the save method calls serializer's create method
                user = serializer.save()
                if user:
                    jwt_payload_handler = api_settings.JWT_PAYLOAD_HANDLER
                    jwt_encode_handler = api_settings.JWT_ENCODE_HANDLER
                    payload = jwt_payload_handler(user)
                    token = jwt_encode_handler(payload)
                    json = serializer.data
                    json['token'] = token
                    return Response(json, status=status.HTTP_201_CREATED)

            return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

    你还需要指定 authentication_classes . 让它为空，它应该工作 .

    我的问题是当我使用django.db.model创建方法创建用户时：

    from . models import User

def create(self, validated_data):
        user = User.objects.create(
            first_name = validated_data['first_name'],
            ...
        )

        return user

    我还没有在django.contrib.auth.models的Django用户模型中创建用户，这是模型Django和JWT框架用于身份验证 . 对于一个初学者来说，这并不是那么简单，考虑到JWT与Django的普及（或者看起来如此），这并不是一个大问题 . 我想有人会告诉我，我应该花更多时间在文档中 .

    我离题了，优雅的解决方法是通过扩展django.contribut.auth.models ' AbstractUser which (I believe) links the pertinent parts of your user model to Django'模型来定制您的用户模型 . 说明：https://docs.djangoproject.com/en/1.11/topics/auth/customizing/

    我做的选项是启动并运行（虽然我计划尽快切换到自定义模型）是使用django.contrib.auth.models的create_user方法将用户对象保存到Django用户模型，该方法与create相同上面的方法，除了它保存到Django的用户模型 .
