對話結束 (Dialogflow)

在 Dialogflow 中探索

點選「繼續」，在 Dialogflow 中匯入 Conversation 離開範例。接著，請按照 部署及測試範例的步驟：

  1. 輸入虛擬服務專員名稱，並為範例建立新的 Dialogflow 代理程式。
  2. 代理程式匯入完畢後，按一下「Go to agent」。
  3. 在主要導覽選單中，前往「Fulfillment」(執行要求)。
  4. 啟用「Inline Editor」(內嵌編輯器)，然後按一下 [Deploy] (部署)。編輯器包含範例 再也不是件繁重乏味的工作
  5. 在主要導覽選單中，前往「Integrations」(整合)，然後按一下「Google」 Google 助理。
  6. 在出現的互動視窗中，啟用「自動預覽變更」，然後按一下「測試」 以開啟動作模擬工具
  7. 在模擬工具中輸入 Talk to my test app 即可測試範例！
繼續

每當使用者想要離開對話中，可以說：

  • "exit"
  • 「取消」
  • "停止"
  • 「不用了」
  • "再見"

根據預設，Google 助理會結束對話並播放音效。 如要覆寫此行為，您可以選擇接收最後一項要求 即可清除執行要求邏輯，以及最後一次回應使用者。 最終回應必須是單一簡單回應 textToSpeech 和 displayText 值最多只能有 60 個半形字元。

對話退出要求的執行時間上限為 2 秒。如果答案為「否」 對話結束後，對話就會以預設的退出耳機結束。 如果您的自訂取消回應失敗 (因為超過字元限制， 不當回應類型等) 對話也會以預設的退出音效結束對話。

Dialogflow

如何接收對話離開事件：

  1. 在左側導覽列中，按一下「Intents」(意圖) 選單項目旁的 + 圖示。
  2. 為意圖命名 (例如 Exit Conversation)，然後按一下「Events」(事件) 部分。
  3. 在「新增事件」欄位中輸入 actions_intent_CANCEL。
  4. 在「Response」下方指定回應，或設定您自己的回應： 在 Webhook 程式碼中執行這項意圖
  5. 啟用「將此意圖設為對話結尾」。
  6. 按一下 [儲存]。
  7. 點選左側導覽面板中的「Integrations」(整合)。
  8. 選擇「Google 助理」，然後依序點選「更新草稿」和「測試」，即可建立 並確保專案已反映相關變更

當使用者要求對話結束時，系統會觸發您建立的意圖， 則會將回應傳回給使用者適用對象 例如，以下的執行要求程式碼使用用戶端程式庫處理 並傳回回應

Node.js

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);
index.js

Java

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

public class MyActionsApp extends DialogflowApp {

  @ForIntent("Exit Conversation")
  public ActionResponse exit(ActionRequest request) {
    ResponseBuilder responseBuilder = getResponseBuilder(request);
    responseBuilder.add("Okay, talk to you next time!");
    responseBuilder.endConversation();
    return responseBuilder.build();
  }
}

回應 JSON

請注意，下列 JSON 會說明 Webhook 回應。

    "google": {
      "expectUserResponse": false,
      "richResponse": {
        "items": [
          {
            "simpleResponse": {
              "textToSpeech": "Okay, talk to you next time!"
            }
          }
        ]
      }
    }
  }
}

Actions SDK

如要接收對話結束意圖，請按照下列步驟操作：

  1. 在動作套件中的 conversations 物件中宣告 且您要接收 actions.intent.CANCEL 意圖的 每當使用者想要在對話中結束時就結束轉換。

    
{
  "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"
        }
      ]
    }
  }
}
    action.json

  2. 收到含有 actions.intent.CANCEL 的要求時 清理任何想使用的執行要求邏輯，然後傳回 提供適當的退出詞組例如以下的執行要求代碼 ，使用用戶端程式庫處理取消意圖。

    Node.js

    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!`);
});

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

  @ForIntent("actions.intent.TEXT")
  public ActionResponse fallback(ActionRequest request) {
    ResponseBuilder responseBuilder = getResponseBuilder(request);
    responseBuilder.add("You said " + request.getRawInput().getQuery());
    responseBuilder.add("Try saying 'exit' or 'cancel'");
    return responseBuilder.build();
  }

  @ForIntent("actions.intent.CANCEL")
  public ActionResponse exit(ActionRequest request) {
    ResponseBuilder responseBuilder = getResponseBuilder(request);
    responseBuilder.add("Okay, talk to you next time!");
    responseBuilder.endConversation();
