python itsdangerous模块的具体使用方法

pip install itsdangerous

import itsdangerous

salt='sdaf'#加盐
t=itsdangerous.TimedJSONWebSignatureSerializer(salt,expires_in=600)#过期时间600秒

info = {'username':'baihe','user_id':1}

# =========加密token============
res=t.dumps(info)
token=res.decode()#指定编码格式
print(token)

from itsdangerous import TimedJSONWebSignatureSerializer as Serializer

salt='abcdefg' # 这里就是配置加密的规则
serializer=Serializer(salt,expires_in=3600) # 过期时间一小时，
info = {'confirm':1}
# 加密阶段
res=serializer.dumps(info)# 得到加密后的数据，会返回一个字节类型的数据
token=res.decode() # 解码为str
print(token)
# 得到的数据如下，就是包含数据和盐值的token了，只有在知道盐值的时候才能被解密出来

# 解密阶段
res=serializer.loads(token)

# 返回的数据如下：
