Heroku Node.js上的Google Actions API Webhook响应

[英]Google Actions API webhook response on Heroku nodejs

 原文  2017-04-30 19:17:08  7   1    node.js/ heroku/ actions-on-google/ google-home

问题描述

问题：Google Actions是否总是通过在每个用户输入上触发webhook帖子而始终起作用，而我仅需工作逻辑以便每次都解析json并仅在找到我感兴趣的参数时做出反应？ 还是有一种方法可以控制Google Actions API所发布的Webhook帖子，以便仅在通过包含相关参数的值来完全填充该操作时才发布它？

＃

详细信息：我已经在Heroku上部署了这个nodejs应用程序： https : //github.com/quique123/myjsonparser/blob/master/app.js

我将它用作Google Actions API（数字精灵）示例的网络挂钩。 在“数字精灵”中，用户使用“与数字精灵对话”开始游戏。 精灵回应我以为我想一个数字...猜对了。 用户用一个数字回答，然后（并且只有这样）才运行逻辑以将猜测与答案进行比较。

但是我在Google Home的每个帖子请求上都进行了api调用。 换句话说，每次用户与会话api交互时，都会发出webhook帖子。 在此处可以看到，该主体不包含用户输入参数，并且Heroku响应“与数字精灵对话”：

而且，当我使用Google Actions API上的数字对其进行测试时，您可以在Heroku的“ 44”响应中看到其中包含check_guess：

问题是在两种情况下都发生postSwitch {}。

这是Google Actions始终可以工作的方式，我只需要工作逻辑以便每次都解析json并仅在找到check_guess时作出反应？ 还是有一种方法可以控制Google Actions API发出的webhook帖子，以便仅在通过包含参数check_guess的值来完全填充该操作时才发布它？

您只能设置一个webhook（一个静态URL），该Webhook将被API.AI触发的所有操作调用。 尽管您将需要解析JSON（使用node.js，但JSON.parse（）并不困难），但您应该使用result.action字段，而不是试图弄清楚设置了哪些参数。 这将与您在API.AI中设置的“操作”字段相对应。

当然，这假设您已选中了Webhook框以进行操作。 如果没有，您将根本不会接到网络电话。

因此，例如，将起始意图配置如下：

在此处输入图片说明

它将将此JSON发送到您的webhook。

虽然Provide_guess意图可能是这样配置的

并将此JSON提供给webhook：

在您的代码中，您将在postSwitch()方法中检查result.action的值，然后可以基于此操作在您的终端上选择确切的操作checkGuess()基于注释掉的代码，可以是generateAnswer()或checkGuess() ） 。
