完成一个媒体响应（音频播放）后，调用另一个播放器

Question

我有问题。

[我选择一个对话流程，谷歌动作示例（播放音频文件）

我想为多个音频文件构建。

因此，在完成媒体响应后，将调用媒体状态。

所以当时我想自动播放下一个音频。

请帮助我。我需要您的帮助。

谢谢。

这是我的代码。

'use strict';

const {
  dialogflow,
  SimpleResponse,
  Image,
  Suggestions,
  MediaObject,
} = require('actions-on-google');
const functions = require('firebase-functions');

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

app.intent('Media Response', (conv) => {
  if (!conv.surface.capabilities
    .has('actions.capability.MEDIA_RESPONSE_AUDIO')) {
      conv.ask('Sorry, this device does not support audio playback.');
      conv.ask('Which response would you like to see next?');
      return;
  }

  conv.ask('This is a media response example.');
  conv.ask(new MediaObject({
    name: 'Jazz in Paris',
    url: 'https://storage.googleapis.com/automotive-media/Jazz_In_Paris.mp3',
    description: 'A funky Jazz tune',
    icon: new Image({
      url: 'https://storage.googleapis.com/automotive-media/album_art.jpg',
      alt: 'Album cover of an ocean view',
    }),
  }));

  conv.ask(new Suggestions(['cancel']));
});

app.intent('Media Status', (conv) => {
  const mediaStatus = conv.arguments.get('MEDIA_STATUS');
  let response = 'Unknown media status received.';
  if (mediaStatus && mediaStatus.status === 'FINISHED') {
    response = 'Hope you enjoyed the tune! ';
  }
  conv.ask(response);
  conv.ask('Media ended successfully');
  conv.ask(new Suggestions(['exit']));
});

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

我尝试针对“媒体状态”意图调用另一个响应。

app.intent('Media Status', (conv) => {
      const mediaStatus = conv.arguments.get('MEDIA_STATUS');
      let response = 'Unknown media status received.';
      if (mediaStatus && mediaStatus.status === 'FINISHED') {
        conv.ask(new MediaObject({
        name: 'Jazz in Paris',
        url: 'https://storage.googleapis.com/automotive-media/Jazz_In_Paris.mp3',
        description: 'A funky Jazz tune',
        icon: new Image({
          url: 'https://storage.googleapis.com/automotive-media/album_art.jpg',
          alt: 'Album cover of an ocean view',
        }),
      }));

      conv.ask(new Suggestions(['cancel']));
    });
      }

    });

然后发生“ Webhook意图失败：媒体状态”错误。我应该如何解决这个问题？谢谢。

所有包含MediaObject的响应还必须包含SimpleResponse-通常只是媒体之前所说的一些文本。

例如，当您发送第一个MediaObject时，在“媒体响应”意图处理程序中，您将看到以下行：

conv.ask('This is a media response example.');

但是“媒体状态”意图处理程序中缺少这种类型的行。
