我通过Dialogflow配置了webhooks，以便轻松处理template chatbot UI starter project I 'm making on Github. I have a bot integrated through Facebook Messenger and Google Assistant. All of Facebook works fine because the actions send back strings and it' . 但是当Google智能助理尝试处理"@type"："type.googleapis.com/google.actions.v2.OptionValueSpec"的项目时，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 .
Facebook Messenger（工作）与Google智能助理的比较（有bug）

发送给Dialogflow的响应随后被发送到Google Actions ...

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
在你的webhook中......
（使其成功的拼图的缺失部分）设置列表选项的输出上下文
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，但是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，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 .
