Question

我通过Dialogflow为我在Github上制作的template chatbot UI starter project配置了webhook。我有一个通过Facebook Messenger和Google智能助理集成的机器人。 Facebook的所有工作都很好，因为动作会发回字符串并且很容易处理。但是，当Google智能助理尝试处理“@type”项目：“type.googleapis.com/google.actions.v2.OptionValueSpec”时，需要在Dialogflow中的事件上执行actions_intent_OPTION来处理响应。如果我的应用程序中只有一个，它工作正常，但是当我添加OptionValueSpec类型的第二个列表项/ carousel项时，流程会阻塞。我有附加图像的详细信息。我的猜测是需要actions_intent_OPTION来处理列表，但是当我把它放在事件部分的多个意图上时，流程不知道如何处理它。

Answer 1

最终有效！谢谢@Prisoner！

在Dialogflow中......

第一个列表，定义输出上下文
第二个列表，定义输入上下文和输出上下文
第二个列表后的问题，定义输入上下文

在您的webhook中......

（使其成功的谜题的缺失部分）设置列表选项的输出上下文

{
    "speech": "",
    "displayText": "",
    "data": { "google": { ... } },
    "contextOut": [
        {
            "name": "carouselExample",
            "lifespan": 0,
            "parameters": null
        }
    ]
}

Answer 2

从广义上讲，问题是Dialogflow在获得action_intent_OPTION事件时不知道您在对话中的位置。对于那个事件，它不会尝试进行实体匹配，但会话上下文的问题通常是一个问题（例如，如果你有两个不同的选项轮播有重叠的答案会发生什么？）。

解决方案有两个方面：

当您发回包含选项信息的响应时，您还应设置传出上下文。您可以在此上下文中包含其他信息，但在您的情况下，听起来就像您只是想跟踪您在对话中的位置。
然后，您可以通过指定每个应触发的上下文来区分两个Intent和option事件。 Dialogflow将匹配事件和上下文，以确定要使用的最佳Intent。
