List_card 在 AoG 中将项目标题而不是键传递给下一个查询

Question

在一个应用程序中，我返回类型为 list_card 的消息，其中带有用于 intent 的选项键。
这是示例查询的 json：

现在的问题是，当我在 AoG 模拟器中点击列表项时，它将 title 项传递给下一个查询。

但是在 Api.ai 模拟器 中进行测试时，它表现良好并将 key 传递给下一个查询。

这里可能是什么问题？
有什么提示吗？

Answer 1

您需要做的是直接在当前意图下设置回退意图。

例如，如果您显示来自默认欢迎意图的列表，您可以执行以下操作。

单击 "Add follow-up intent" 并选择回退。
不要忘记在回退意图中设置操作并启用 webhook。

现在，您应该能够使用以下代码从回退意图中检索答案。

const param = app.getContextArgument('actions_intent_option','OPTION').value;

Answer 2

如果您正在使用 API.AI，那么它将作为 actions_intent_OPTION 事件出现在 Intent 中。

一个好的解决方案是让 Intent 发送带有 OutputContext 的列表。然后创建一个特定的后备意图，其中 actions_intent_OPTION 作为事件，你想要的 action 作为该上下文，它应该处理语音和新闻响应。

你会在 ["originalRequest"]["data"]["inputs"][0]["arguments"][0]["textValue"] 处找到你的 option_key 而不是参数。

您还可以在 actions_intent_option 上下文中查看响应值。
