所以在我的应用程序成功Google Account linking后，我使用Android设备测试它没有任何问题 . 我使用了Dialogflow响应的“in conversation prompt " technique to request the user to authenticate to proceed further. In other words, I was successfully able to receive the " user”属性和有效的accessToken（以及其他信息） .

现在，我在Google Home设备上试用了它 . 该设备配置了我在Android移动设备上使用的相同电子邮件ID . 当我调用它时，G.Home成功加载了应用程序 . 但这里缺少的部分是用户属性中的accessToken（下面的JSON） . 我在上面的场景中假设了以下内容：

  • 由于我已经在Android移动设备上成功登录，下次我尝试在同一设备上调用该应用程序时，该应用程序不会提示“登录”，因为它已经具有accessToken（直到它是过期） . 由于我在G. Home设备上使用相同的gmail地址，我也应该获得相同的accessToken .

  • 只要使用相同的gmail地址，无论我使用哪种设备/表面对我自己进行身份验证，如果它尚未过期，我将始终获得accessToken .

整个Google帐户关联的设置/配置在我分享的上述链接中有详细说明 . 这是我分别在G. Home和Android设备上收到的JSON：

我的问题是，当我使用Google Home设备时，我在哪里可以获得 accessToken ？
