对话退出 (Dialogflow)

在 Dialogflow 中探索

点击继续,将我们的对话退出示例导入 Dialogflow 中。然后,按照 部署和测试示例的步骤如下:

  1. 输入代理名称并为示例创建新的 Dialogflow 代理。
  2. 代理导入完成后,点击转到代理 (Go to agent)。
  3. 在主导航菜单中,前往 Fulfillment
  4. 启用内嵌编辑器,然后点击部署。编辑器包含示例 代码。
  5. 在主导航菜单中,前往 Integrations(集成),然后点击 Google Google 助理
  6. 在显示的模态窗口中,启用 Auto-preview changes(自动预览更改),然后点击 Test(测试) 打开 Actions 模拟器。
  7. 在模拟器中,输入 Talk to my test app 以测试该示例!
继续

每当用户想在对话过程中退出时,都可以这样说:

  • "exit"
  • “取消”
  • “停止”
  • “不用了”
  • 再见

默认情况下,Google 助理会退出你的对话并播放耳标。 要改变这种行为,您可以选择接收 可用于清理执行方式逻辑并最后一次响应用户。 您的最终响应必须是一条简单响应textToSpeechdisplayText 值的长度上限为 60 个字符。

对话退出请求允许的最长执行时间为 2 秒;如果否 收到回应时,系统会以默认退出耳标结束对话。 如果您的自定义取消响应失败(由于超出字符数限制, 响应类型不正确等),对话也会以默认退出耳标结束。

Dialogflow

若要接收对话退出事件,请执行以下操作:

  1. 在左侧导航栏中,点击意图菜单项旁边的 + 图标。
  2. 为 intent 命名(如 Exit Conversation),然后点击 Events 部分。
  3. 添加事件字段中输入 actions_intent_CANCEL
  4. 您可以在响应 (Response) 下指定响应,也可以自行设置针对 将此 intent 添加到网络钩子代码中。
  5. 启用将此 intent 设为对话结束
  6. 点击保存
  7. 在左侧导航栏中,点击集成
  8. 选择 Google 助理,然后依次点击更新草稿测试 确保这些更改已反映在项目中

当用户请求退出对话时,系统会触发您创建的意图, 响应返回给用户。对于 下面是一些使用客户端库处理 取消意图并返回响应。

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

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

app
.intent('Exit Conversation', (conv) => {
  conv
.close(`Okay, talk to you next time!`);
});

exports
.dialogflowFirebaseFulfillment = functions.https.onRequest(app);
package com.example;

import com.google.actions.api.ActionRequest;
import com.google.actions.api.ActionResponse;
import com.google.actions.api.DialogflowApp;

import com.google.actions.api.response.ResponseBuilder;

public class MyActionsApp extends DialogflowApp {

 
@ForIntent("Exit Conversation")

ResponseBuilder responseBuilder = getResponseBuilder(request);
    responseBuilder
.add("Okay, talk to you next time!");
    responseBuilder
.endConversation();
   
return responseBuilder.build();
 
}
}

Actions SDK

如需接收对话退出 intent,请执行以下操作:

  1. 在操作包内的 conversations 对象中,声明 您希望接收 actions.intent.CANCEL intent 每当用户想要在对话过程中退出时。


    {
     
    "actions": [
       
    {
         
    "description": "Default Welcome Intent",
         
    "name": "MAIN",
         
    "fulfillment": {
           
    "conversationName": "conversation_1"
         
    },
         
    "intent": {
           
    "name": "actions.intent.MAIN"
         
    }
       
    }
     
    ],
     
    "conversations": {
       
    "conversation_1": {
         
    "name": "conversation_1",
         
    "url": "YOUR_ENDPOINT_URL",
          "inDialogIntents": [
            {
              "name": "actions.intent.CANCEL"
            }
          ]
       
    }
     
    }
    }
  2. 收到 actions.intent.CANCEL 的请求后 intent,清理您想要的所有 fulfillment 逻辑,并返回一个 提供适当的退出短语例如,以下是一些执行方式代码 使用客户端库处理取消 intent 的代码。

    const {actionssdk} = require('actions-on-google');
    const functions = require('firebase-functions');

    const app = actionssdk({debug: true});

    app
    .intent('actions.intent.MAIN', (conv) => {
      conv
    .ask(`Hi! Try saying 'exit' or 'cancel'`);
    });

    app
    .intent('actions.intent.TEXT', (conv, input) => {
      conv
    .ask(`You said ${input}`);
      conv
    .ask(`Try saying 'exit' or 'cancel'`);
    });

    app
    .intent('actions.intent.CANCEL', (conv) => {
      conv
    .close(`Okay, talk to you next time!`);
    });

    exports
    .dialogflowFirebaseFulfillment = functions.https.onRequest(app);

    ResponseBuilder responseBuilder = getResponseBuilder(request);
        responseBuilder
    .add("Hi! Try saying 'exit' or 'cancel'");
       
    return responseBuilder.build();
     
    }

        responseBuilder
