1.jwt Advantages and disadvantages
jwt The advantages of :
1. It's very convenient to implement distributed single sign on
2. The data is actually stored on the client side , So we can share the storage pressure of database or server
jwt The shortcomings of :
1. The data is saved on the client side , We only recognize jwt, The client is not recognized . 2. jwt You can set the expiration time , But because the data is stored on the client side , So it's not easy to adjust the expiration time .
2. install jwt
pip install djangorestframework-jwt -i https://pypi.douban.com/simple
3. stay settings.dev in
REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework_jwt.authentication.JSONWebTokenAuthentication', 'rest_framework.authentication.SessionAuthentication', 'rest_framework.authentication.BasicAuthentication', ), } import datetime JWT_AUTH = { 'JWT_EXPIRATION_DELTA': datetime.timedelta(days=1), ## Set up token Effective value }
4. Generate... Manually jwt
from rest_framework_jwt.settings import api_settings 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)
5. The back end implements the login authentication interface ( In sub application routing urls.py in )
from rest_framework_jwt.views import obtain_jwt_token urlpatterns = [ path(r'login/', obtain_jwt_token), ## Provide the interface ]
6. Custom return data ,(user.utils.jwt_response_payload_handler Under the path )
def jwt_response_payload_handler(token, user=None, request=None): """ Customize jwt Authentication successful return data """ return { 'token': token, 'id': user.id, 'username': user.username }# This is custom jwt Authentication successful return data , It's usually placed under sub applications utils In file , And then in settings Middle configuration , Tell the path django
7. modify settings.dev The configuration file
# JWT JWT_AUTH = { 'JWT_EXPIRATION_DELTA': datetime.timedelta(days=1), 'JWT_RESPONSE_PAYLOAD_HANDLER': 'user.utils.jwt_response_payload_handler', }
