【问题描述】：
我正在构建一个 Alexa Skill，它要求我存储用户的 userId。我尝试使用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]。我查看了几个类似的问题，但没有一个为我提供足够清晰的答案。
我不确定这是否是一个错误、仅限开发人员使用，或者 userId 是否只是匿名的。如果是这样，有没有办法获取实际的用户 ID？我想会有，因为亚马逊在这里写了一个完整的指南：
但是，经过一整天的调试，我不确定什么是真实的，什么不再是真实的。
var request = require('request');
var firebase = require('firebase');
var config = {
apiKey: "my-api-key",
authDomain: "stuff...",
databaseURL: "more stuff...",
storageBucket: "even more stuff...",
};
firebase.initializeApp(config);
// Get a reference to the database
var database = firebase.database();
exports.handler = (event, context) => {
try {
// New session
if (event.session.new) {
// New Session
console.log("NEW SESSION");
}

for (i = 0; i < pin.length; i++){
var currentChar = pin.charAt(i);

}
return processedPin
}

因为让我微笑而被投票赞成：“但是，经过一整天的调试，我不确定什么是真实的，什么不再是真实的。”哦，还因为这是一个非常详细的问题！
