對話結束 (Dialogflow)

在 Dialogflow 中探索

按一下「Continue」，即可在 Dialogflow 中匯入對話結束範例。接著，請按照下列步驟部署及測試範例：

  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. 代理程式匯入完成後，按一下「Go to agent」。
  3. 從主要導覽選單中，前往「Fulfillment」。
  4. 啟用「Inline Editor」(內嵌編輯器)，然後按一下「Deploy」(部署)。編輯器包含程式碼範例。
  5. 在主要導覽選單中，前往「Integrations」(整合)，然後按一下「Google Assistant」(Google 助理)。
  6. 在出現的互動視窗中，啟用「Auto-preview changes」，按一下「Test」，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

當使用者想結束對話時，可以說：

  • "exit"
  • 「取消」
  • "stop"
  • "永不過期"
  • "再見"

根據預設，Google 助理會結束對話並播放音效。 如要覆寫這項行為，您可以選擇接收最後一項要求，可用於清除執行要求邏輯，並在最後一次回應使用者時使用。您的最終回應必須是單一簡單回應，且 textToSpeech 和 displayText 值的長度限制為 60 個字元。

對話結束要求允許的執行時間上限為 2 秒。如未收到回應，對話將會以預設的結束耳機結束。如果自訂取消回應失敗 (因超過字元限制、回應類型不正確等)，對話也會以預設的結束音效結束。

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) 區段。
  3. 在「Add event」(新增事件) 欄位中輸入 actions_intent_CANCEL。
  4. 請在「Response」下方指定回應，或是在 Webhook 程式碼中自行設定這個意圖的回應。
  5. 啟用「將這項意圖設為對話結尾」。
  6. 點按「儲存」。
  7. 在左側導覽面板中按一下「Integrations」。
  8. 選擇「Google Assistant」，然後依序點選「Update draft」和「Test」，確認變更已反映在專案中。

使用者要求結束對話時，系統會觸發您建立的意圖，並將回應傳回給使用者。舉例來說，下方的執行要求程式碼會使用用戶端程式庫處理取消意圖及傳回回應。

Node.js

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

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

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

          }
        ]
      }
    }
  }
}

Actions SDK

如要接收對話結束意圖：

  1. 在動作套件的 conversations 物件中，宣告您希望在使用者結束對話時收到 actions.intent.CANCEL 意圖。

    
{
  "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 意圖的要求時，請清除所需的任何執行要求邏輯，然後將適當的結束詞組傳回給使用者。例如，以下是一些使用用戶端程式庫處理取消意圖的執行要求程式碼。

    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!`);
});

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

  @ForIntent("actions.intent.MAIN")
  public ActionResponse welcome(ActionRequest request) {
    ResponseBuilder responseBuilder = getResponseBuilder(request);
    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();
    return responseBuilder.build();
