dialogflow-es - 如何在 Dialogflow 中获取用户 ID 和 OAuth 访问令牌

Question

在 webhook（用Java编写）中，作为配置为使用以下拓扑链接帐户的操作的一部分：

Actions-on-Google->Dialogflow->Webhook,

我正在尝试从传入请求中提取userId和 OAuth accessToken 。

两个初始请求（在链接流程开始之前）：

 [java] }

似乎包含该userId领域。唯一的accessToken开始出现在链接之后，这是正确的。

但是，在我的 webhook 中，在这两种情况下，我都使用以下内容来捕获userIdand accessToken（除了其他东西）：

private void logUserDetails(ActionRequest request) {

    String userId = request.getAppRequest().getUser().getUserId();
    log.info("request.getAppRequest().getUser().getUserId()={}",userId);

    String idToken = request.getUser().getIdToken();
    log.info("idToken={}",idToken);

    String usrId = request.getUser().getUserId();
    log.info("request.getUser().getUserId()={}",usrId);

    String queryText = request.getWebhookRequest().getQueryResult().getQueryText();
    log.info("queryText={}", queryText);
}

在这两种情况下，我都看到它们都返回为null：

预帐户链接：

[java] 02-25-2019 16:41:33  INFO  AoGApp [logUserDetails:23]    - request.getAppRequest().getUser().getUserId()=null
 [java] 02-25-2019 16:41:33  INFO  AoGApp [logUserDetails:26]    - idToken=null
 [java] 02-25-2019 16:41:33  INFO  AoGApp [logUserDetails:29]    - request.getUser().getUserId()=null
 [java] 02-25-2019 16:41:33  INFO  AoGApp [logUserDetails:32]    - queryText=GOOGLE_ASSISTANT_WELCOME

发布帐户链接：

[java] 02-25-2019 16:43:25  INFO  AoGApp [logUserDetails:23]    - request.getAppRequest().getUser().getUserId()=null
     [java] 02-25-2019 16:43:25  INFO  AoGApp [logUserDetails:26]    - idToken=null
     [java] 02-25-2019 16:43:25  INFO  AoGApp [logUserDetails:29]    - request.getUser().getUserId()=null
     [java] 02-25-2019 16:43:25  INFO  AoGApp [logUserDetails:32]    - queryText=actions_intent_SIGN_IN

通过 Java API，queryText似乎是唯一一个提取实际值的方法，但对于来自传入请求的其他字段而言并非如此，它们都是null.

我有一些问题：

Google在什么时候userId创建了 get 以及触发了它的创建？换句话说，是否存在userId请求中的实际是的情况null，在其值生成之前，我是否能够在进入我的 webhook 的请求中看到这种情况？
如何从进入我的 webhook 的请求中提取其他字段？我做错了什么，以至于通过 Java API 解析请求返回的结果与原始请求中看到的值不同？
