##加密及解密演示

解密时间超时演示

from  itsdangerous import TimedJSONWebSignatureSerializer as Serializer
from django.confo import SECRET_KEY
#创建类
serializer = Serializer(settings.SECRET_KEY,3600)
info = {'confirm':123456}
#加密
token = serializer.dumps(info)
#加密编码
token = token.decode('utf-8')#默认可以省略utf-8





#解密超时会报错
from itsdangerous import SignatureExpired

#解密
serializer = Serializer(settings.SECRET_KEY,3600)
try:
	serializer.loads(token)
except SignatureExpired as e:
	return print("解密超时")
