Django 配置JWT认证方式

1. 安装 rest_framework + djangorestframework_simplejwt

安装djangorestframework_simplejwt ：pip install djangorestframework-simplejwt

安装rest_framework： pip install djangorestframework

djangorestframework_simplejwt 是提供 jwt 的 django 应用。

2. 配置好 rest_framework 后，settings.py 里加上以下内容以支持 jwt认证

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'rest_framework_simplejwt.authentication.JWTAuthentication',
    ],
}

3. 写个测试的 view

from rest_framework import permissions
from rest_framework_simplejwt import authentication
class TestView(views.APIView):
    permission_classes = [permissions.IsAuthenticated]
    authentication_classes = (authentication.JWTAuthentication,)
    def get(self, request, *args, **kwargs):
        return Response('ok')

4.urls.py 导入 jwt 的两个 view

from rest_framework_simplejwt.views import (
    TokenObtainPairView, 
    TokenRefreshView,     
)

urlpatterns = [
   ...
    url(r'^api/auth/token/obtain/$', TokenObtainPairView.as_view()),	# 需要添加的内容
    url(r'^api/auth/token/refresh/$', TokenRefreshView.as_view()),	# 需要添加的内容
    url(r'^api/test/$', TestView.as_view()),	# 添加测试views的路由
   ...
]

5. 获取Token

先启动 server 端口为默认的8000

方式一：通过curl

cmd 里运行 curl，获取 token

curl   -X POST   -H "Content-Type: application/json"   -d '{"username": "abab", "password": "abab123456"}'   http://localhost:8000/api/auth/token/obtain/

结果返回了 token

{"access":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ0b2tlbl90eXBlIjoiYWNjZXNzIiwidXNlcl9pZCI6MywianRpIjoiZDRlMTJiMjk0M2ZiNGFkYTg1NzZiNWIzMzcyY2RlMjQiLCJleHAiOjE1MzE1MDY5Njl9.S1MPTw359xVK-GpmJary1fZwDsHb8yXsVtyf-tCbHM8","refresh":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ0b2tlbl90eXBlIjoicmVmcmVzaCIsInVzZXJfaWQiOjMsImp0aSI6IjAyYWM3NmQ0MDBkNzRlYzNhOGU5NDM2MWYzYzUzMWQyIiwiZXhwIjoxNTMxNTkzMDY5fQ.rXkYG2SJ74vof3rA38xX-EfMagHxeQRv7ZolszofuHA"}

方式二：通过PostMan 软件

只需要设置如下三个地方就可以了

postman获取token

6. 提供 token，获取 testview 的信息

方式一：通过curl

curl \
>   -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ0b2tlbl90eXBlIjoiYWNjZXNzIiwidXNlcl9pZCI6MywianRpIjoiZDRlMTJiMjk0M2ZiNGFkYTg1NzZiNWIzMzcyY2RlMjQiLCJleHAiOjE1MzE1MDY5Njl9.S1MPTw359xVK-GpmJary1fZwDsHb8yXsVtyf-tCbHM8" \
>   http://localhost:8000/api/test/
"ok"
