解密jwt-django

需要在根目录下创建一个文件夹

里面写入代码 

import jwt, time
from django.conf import settings
from django.utils.deprecation import MiddlewareMixin

class UserMiddleware(MiddlewareMixin):
    def process_request(self, request):

        # 获取前台发送的信息
        token = request.META.get('HTTP_TOKEN')

        # 解密
        try:
            user = jwt.decode(token, settings.SECRET_KEY, algorithms='HS256')
            # 判断是否过期
            if user['exp'] < int(time.time()):
                user = None
        except:
            user = None

        # 在次插入给视图
        request.META['USER'] = user

在配置项目

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware'
]
