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 其 textToSpeech 和 displayText 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. 在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和测试 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。

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!`);
});

响应 JSON

请注意，下面的 JSON 描述的是 webhook 响应。

    "google": {
      "expectUserResponse": false,
      "richResponse": {
        "items": [
          {
            "simpleResponse": {

            }
          }
        ]
      }
    }
  }
}

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"
        }
      ]
    }
  }
}
    action.json

  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。

    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!`);
});

    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);
