如何在 Google Assistant 中显示来自 Dialogflow Webhook 的表格卡片

Question

我已经设置了一个 ASP.NET MVC 4 Web API来处理dialogflow的实现。我的目标是与 Google Assistant 集成并显示表格卡片作为响应。我正在通过谷歌行动控制台模拟器进行测试。

我根据我在这里发现的内容，在GoogleCloudDialogflowV2IntentMessagePayload字段中添加了表格卡片详细信息：

如何在对话流履行中添加表格卡？

来自我的 API Webhook 的履行响应最终看起来像这样：

{
"followupEventInput": {
"languageCode": null,
"name": null,
"parameters": null,
"ETag": null
},
"fulfillmentMessages": [

问题是我在模拟器中看不到表格卡。我的JSON响应格式可能不正确，所以谷歌助理无法正确解释它，但我不知道如何更改它。我不知道正确的格式是什么。或者也许我错过了别的东西。

任何帮助/其他想法表示赞赏。

Answer 1

通过查看对话流控制台>诊断信息>履行状态。

我发现在GoogleCloudDialogflowV2IntentMessage中，我同时设置了SimpleResponses字段和Payload字段;而Google Assistant不太喜欢这样。因此，我将SimpleResponses字段设置为null，然后在 Google 操作模拟器上获得所需的显示响应。

SimpleResponses已经添加到Payload字段中，Google Assistant对此没有问题，只是设置了Payload和SimpleResponses
