itsdangerous模块
安装：pip install itsdangerous
TimedJSONWebSignatureSerializer的使用
使用TimedJSONWebSignatureSerializer可以生成带有有效期的token
from itsdangerous import TimedJSONWebSignatureSerializer as Serializer
from django.conf import settings
# serializer = Serializer(秘钥, 有效期秒)
serializer = Serializer(settings.SECRET_KEY, 300)
# serializer.dumps(数据), 返回bytes类型
token = serializer.dumps({'mobile': '18512345678'})
token = token.decode()
# 检验token
# 验证失败，会抛出itsdangerous.BadData异常
serializer = Serializer(settings.SECRET_KEY, 300)
try:
data = serializer.loads(token)
except BadData:
return None
补充：openid签名处理
oauth.utils.py
def generate_eccess_token(openid):
"""
签名openid
:param openid: 用户的openid
:return: access_token
"""
serializer = Serializer(settings.SECRET_KEY, expires_in=constants.ACCESS_TOKEN_EXPIRES)
data = {'openid': openid}
token = serializer.dumps(data)
return token.decode() |
