视觉选择响应 (Dialogflow)

在 Dialogflow 中探索

点击继续,将我们的响应示例导入 Dialogflow。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!

如果您希望用户在 以继续您的 Action。

视觉选择响应可以显示在纯屏幕体验中或 兼具音频和屏幕组件的体验。

视觉选择响应可包含以下组成部分:

您还可以查看我们的对话设计准则, 了解如何在您的 Action 中融入这些视觉元素。

属性

视觉选择响应具有以下要求(可选) 您可以配置以下属性:

  • 在具有 actions.capability.SCREEN_OUTPUT 功能的 Surface 上受支持。
  • 视觉选择响应中的第一项必须是简单回复
  • 最多一个简单回复。
  • 最多一张基本卡片和选项界面(列表轮播), 或 StructuredResponse。(您不能同时拥有基本卡片和选项 界面)。
  • 最多 8 个建议内容信息卡
  • FinalResponse中不允许使用建议内容信息条。

以下部分介绍了如何构建各种类型的视觉选择 响应。

列表

。 <ph type="x-smartling-placeholder">
</ph>
图 1.列表示例(智能手机)

单选列表会向用户显示包含多个项目的纵向列表 并允许用户选择一项从列表中选择商品 生成包含列表项标题的用户查询(聊天气泡)。

具有以下特征的平台支持列表响应类型: actions.capability.SCREEN_OUTPUT 功能。

属性

列表必须包含至少 2 到 30 个列表项。列表包含 以下属性:

  • 列表标题(可选) <ph type="x-smartling-placeholder">
      </ph>
    • 固定的字体和字号
    • 仅限一行。(过长的字符会被截断。)
    • 纯文本,不支持 Markdown。
    • 如果未指定标题,卡片高度会收起。
  • 列表项 <ph type="x-smartling-placeholder">
      </ph>
    • 标题
      • 固定的字体和字号
      • 长度上限:1 行(用省略号截断...)
      • 必须唯一(以便支持语音选择)
    • 说明(可选) <ph type="x-smartling-placeholder">
        </ph>
      • 固定的字体和字号
      • 长度上限:2 行(用省略号截断...)
    • 图片(可选) <ph type="x-smartling-placeholder">
        </ph>
      • 尺寸:48x48 像素
  • 互动 <ph type="x-smartling-placeholder">
      </ph>
    • 语音/短信 <ph type="x-smartling-placeholder">
        </ph>
      • 用户可以随时说出或输入项的名称,而不是点按该项。
      • 必须具有用于处理触控输入的 intent actions_intent_OPTION 事件。

指南

列表适用于消除选项的歧义,或者 用户需要在需要一目了然的选项之间进行选择。 例如,“Peter”你需要跟 Peter Jons 或 Peter Hans 对话吗?

我们建议在列表下方添加建议内容信息卡,以便用户 转变或展开对话。切勿重复 将列表显示为建议内容信息卡。此上下文中的条状标签用于透视 对话(不用于选择内容)。

请注意,在随附的示例中, 列表卡片是音频的子集 (TTS/SSML)。音频输出 仅包含第一个列表项。我们不建议在 。

确保您的 Action 会显示对用户而言最重要的内容 展示在列表顶部(例如,最热门、最近购买或 讨论最多)。列表最初最多可显示 10 个元素, 可以展开列表以显示更多元素列表中的项的数量 也可能会因为广告表面和时间而发生变化。

处理所选商品

当用户选择某项内容时,所选内容值会作为 参数。在参数值中,您可以获取key 所选项:

Node.js

app.intent('List - OPTION', (conv, params, option) => {
  const SELECTED_ITEM_RESPONSES = {
    'SELECTION_KEY_ONE': 'You selected the first item',
    'SELECTION_KEY_GOOGLE_HOME': 'You selected the Google Home!',

  };
  conv.ask(SELECTED_ITEM_RESPONSES[option]);
  conv.ask('Which response would you like to see next?');
});

Java

    • 向左/向右滑动:滑动轮播界面即可显示不同的卡片。
    • 点按卡片:点按某物品只生成一个聊天气泡 text 作为元素标题。
      • 必须具有用于处理 actions_intent_OPTION 事件的触摸输入 intent。

指南

轮播界面适用于向用户显示各种选项,但直接 之间不需要进行比较(与列表相比)。一般来说,最好 列表改为轮播界面,因为列表更易于直观地浏览和浏览 语音互动。

如果您希望构建包含链接到网页的商品的轮播界面, 不妨改为构建浏览轮播界面

如果您想继续,建议您在轮播界面下方添加建议内容信息条 对话。

切勿将列表中显示的选项作为建议内容信息卡重复出现。输入的条状标签 用于转换对话(而不是用于选择)。

与列表一样,随轮播卡片一起显示的聊天气泡 音频子集 (TTS/SSML)。这里的音频 (TTS/SSML) 集成了 图块,同时我们也强烈建议不要读取 轮播界面建议你先说明第一项内容及其原因 (例如,最热门、最近购买或 )。

当用户选择某项内容时,所选内容值会作为 参数。在参数值中,您可以获取key 所选项:

Node.js
