Dialogflow es 使用确认帮助程序时的自定义回退意图

我正在尝试为包含确认的意图创建自定义回退。代码如下：

const functions = require('firebase-functions');
const {
    dialogflow,
    Confirmation
} = require('actions-on-google');


const app = dialogflow({
    debug: true,
});

app.intent('vitals-confirmation', (conv, input, confirmation) => {
    conv.ask(new Confirmation(`Great! Have you fainted recently?`));
});

app.intent('vitals-confirmation-fallback', (conv, input, confirmation) => {
    conv.ask(new Confirmation(`Sorry I didn't understand what you said. Did you faint?`));
})

app.intent('S1-confirmation', (conv, input, confirmation) => {
    if (confirmation) {
        conv.ask(new Confirmation(`I have recorded that you have fainted. Have your feet been hurting?`));
    } else {
        conv.ask(new Confirmation(`I have recorded that you have not fainted. Have your feet been hurting?`));
    }
});

我的应用程序会询问用户是否在“vitals confirmation”中晕倒，用户需要回答“是”或“否”类型的答案，该答案将由确认助手识别，如果他们正确回答，他们将转到“S1 confirmation”，并被问到下一个问题

但是，当我用非是/否类型的答案（例如：“红色”）回答时，输出以下内容：

似乎有一个默认的回退，响应为“对不起，[重复以前的文本输出]”，而不是我创建的自定义回退意图（这是我想要的结果）。

看看Node.js SDK的操作

为了检索用户响应，您必须在DialogFlow中使用

操作\u意图\u确认

事件设置意图。我的建议是检查如何配置意图并使用此方法，否则请确保创建具有所需上下文寿命的后续意图

文档中的示例：

app.intent('Default Welcome Intent', conv => {
  conv.ask(new Confirmation('Are you sure you want to do that?'))
})

// Create a Dialogflow intent with the `actions_intent_CONFIRMATION` event
app.intent('Get Confirmation', (conv, input, confirmation) => {
  if (confirmation) {
    conv.close(`Great! I'm glad you want to do it!`)
  } else {
    conv.close(`That's okay. Let's not do it now.`)
  }
})

您能否更新您的问题以显示意图是如何配置的？

app.intent('Default Welcome Intent', conv => {
  conv.ask(new Confirmation('Are you sure you want to do that?'))
})

// Create a Dialogflow intent with the `actions_intent_CONFIRMATION` event
app.intent('Get Confirmation', (conv, input, confirmation) => {
  if (confirmation) {
    conv.close(`Great! I'm glad you want to do it!`)
  } else {
    conv.close(`That's okay. Let's not do it now.`)
  }
})
