在使用Django REST framework想用JWT的人会发现django-rest-framework-jwt已经停止了更新版本，其对新版本的Django REST framework并不支持，在这推荐django-rest-framework-simplejwt支持django2到3版本python3.7到3.9

1.安装

pip install django-rest-framework-simplejwt

2.配置

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework_simplejwt.authentication.JWTAuthentication',
    )

}

2.1 URL配置

from rest_framework_simplejwt.views import (
    TokenObtainPairView,
    TokenRefreshView,
)

urlpatterns = [
    ...
    # 认证令牌
    path('api/token/', TokenObtainPairView.as_view(), name='token_obtain_pair'),
    # 刷新令牌
    path('api/refresh/', TokenRefreshView.as_view(), name='token_refresh'),
    ...
]

如果您希望允许API用户无需访问您的签名密钥即可验证HMAC签名的令牌，还可以包括一个简单JWT的路由

urlpatterns = [
    ...
    path('api/token/verify/', TokenVerifyView.as_view(), name='token_verify'),
    ...
]

2.2用postman测试

3. 设置自定义返回值

在app的 views中创建

from rest_framework_simplejwt.serializers import TokenObtainPairSerializer
from rest_framework_simplejwt.views import TokenObtainPairView


class MyTokenObtainPairSerializer(TokenObtainPairSerializer):
    def validate(self, attrs):
        data = super().validate(attrs)
        refresh = self.get_token(self.user)
        data['refresh'] = str(refresh)
        data['access'] = str(refresh.access_token)

        # Add extra responses here
        data['username'] = self.user.username
        data['groups'] = self.user.groups.values_list('name', flat=True)
        return data


class MyTokenObtainPairView(TokenObtainPairView):
    serializer_class = MyTokenObtainPairSerializer

在url中配置

from .views import MyTokenObtainPairView
urlpatterns = [

    path(r'login2/', MyTokenObtainPairView.as_view()),
]
