python实现小程序“成语猜题”openid生成3rd_session 加密以及对应解密

#openid生成3rd_session 加密

def get3rd_session(openid):

key = Fernet.generate_key()

cipher = Fernet(key)

encrypted_data = cipher.encrypt(openid.encode('utf-8'))

return encrypted_data, key

 

#3rd_session生成openid 解密

def getopenid_from_session(encrypted_data, key):

cipher = Fernet(key)

raw_data = cipher.decrypt(encrypted_data)

return raw_data
