如何获取 Alexa 用户 ID? [英] How to get an Alexa userId?
问题描述
我正在构建 Alexa Skill，它要求我存储用户的 userId.我试图用 event.session.user.userId 检索它.但是，当我调用 console.log(event.session.user.userId) 时，输出实际上是 amzn1.ask.account.[unique-value-here].我看过几个类似的问题，但没有一个为我提供足够明确的答案.
I'm building an Alexa Skill, and it requires that I store the userId of a user. I've tried to retrieve it with event.session.user.userId. However, when I call console.log(event.session.user.userId) the output is literally amzn1.ask.account.[unique-value-here]. I've looked at several similar questions, and none of them provide a clear enough answer for me.
我不确定这是否是错误、仅限开发人员的事情，或者 userId 是否只是匿名的.如果是这样，有没有办法获得实际的用户 ID?我想会有，因为亚马逊在这里写了一个完整的指南:
I'm not sure if this is a bug, a developer-only thing, or if the userId is simply anonymized. If so, is there a way to get the actual userId? I imagine there would be, since Amazon has written an entire guide on it here:
然而，经过一整天的调试，我不确定什么是真实的，什么不再是了.
However, after a long day of debugging, I'm not sure what's real and what's not anymore.

推荐答案
好吧，事实证明我做的一切都是正确的(一次).userId 实际上是 amzn1.ask.account.[unique-value-here] 的原因是因为我在Alexa 启动会话"上测试它.AWS Lambda 控制台中的测试事件.当我让 Echo Dot 启动该技能时，它生成了实际的密钥.问题解决了.
Well, turns out I was doing everything correctly (for once). The reason why the userId was literally amzn1.ask.account.[unique-value-here] was because I was testing it on a "Alexa Start Session" test event in the AWS Lambda console. When I asked my Echo Dot to launch the skill, it generated the actual key. Problem solved.
