Session 如何在webhook上获取会话id

我正在为google home和Android mobile assistant制作助手应用程序

我正在使用webhook上的库，这是推荐的，而且很方便

在我的特定情况下，我想从webhook创建一个会话Id，但我无法在webhook上获取会话Id

据了解，它将Json发送到webhook，如下所示：

支持人士说:

嗨

感谢您对谷歌行动的兴趣。如果您正在使用 nodejs对于您的webhook，您应该能够访问sessionId 使用request.body.sessionId。可以将该值存储在变量中 并在函数的后续阶段使用它

问候

您是否在google node js客户端库上使用操作？是的，在google上使用操作您可能会遇到API.AI sessionID来自GAC对话ID的问题，也许你是通过API.AI UI而不是GAC模拟器进行测试。我正在使用GAC模拟器进行测试。目前，当使用客户端库时，无法获得

seSSIONID

。是的，但你使用的是TypeScript，而不是一般的Javascript库。我已经完成了测试，它在TypeScript中为我工作，但仍在寻找一个干净的脚本解决方案
