途徑功能 (Dialogflow)

試試程式碼片段：使用新的 Dialogflow 代理程式。

在 Dialogflow 中探索

在 Dialogflow 中探索

點選「繼續」，在 Dialogflow 中匯入 Surface 功能範例。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 取消

你的動作可以顯示在多種位置，包括只播放音訊 途徑 (智慧音箱) 、音訊和顯示介面 (例如智慧螢幕和 行動裝置)。

如要設計及建構適用於所有介面的對話，請使用途徑 可妥善控制及界定對話範圍

動作介面功能

Actions on Google 可讓您控制使用者是否能叫用您的動作，根據 並在使用者使用的介面上如果使用者嘗試在 但系統顯示錯誤訊息，指出裝置 不支援。

您可以在 Actions 專案中定義動作的介面支援。

注意： 只有在符合下列條件的情況下，您才能勾選媒體播放途徑功能選項 整個動作取決於媒體播放。舉例來說 除了播放會輸出媒體回應的音軌外，也不會進行任何操作。 請勾選此選項如果您的動作有其他資訊 例如股市資料，您不會勾選這個選項如果是後者 會以程式輔助方式 檢查媒體播放介面功能 並據此回覆

你的動作會顯示在多種 支援的 Google 助理，例如智慧型手機 (Android 和 iOS) Google Home 裝置。

執行階段途徑功能

您可以透過兩種主要方式，利用執行階段表面功能提供使用者體驗：

• 回應分支：向使用者顯示不同的回應，但具備 採用相同結構和流程適用對象 舉例來說，天氣動作可能在手機上顯示一張含有圖片的資訊卡 在 Google Home 上播放音訊檔案，但對話過程相同 跨平台顯示資訊

• 分支對話：向使用者呈現完全不同的畫面 在每個介面上進行對話舉例來說，如果你要打造訂餐服務 應用程式時，建議在 Google Home 上提供重新訂購流程，但 手機的購物車組件流程如要進行對話分支，請設定範圍 透過 Dialogflow 觸發特定介面功能的意圖 定義。除非是特定要求，否則不會觸發實際的 Dialogflow 意圖 表面功能來滿足需求

  注意： 使用者裝置的介面功能可能會改變對話期間的樣貌。 對話出現後，不要依靠的功能組合

• 多介面對話：讓使用者在單一對話中對話 轉換至其他介面的介面。舉例來說 使用者透過 Google 等純音訊介面上的圖片叫用您的動作 進入首頁，即可建構動作，用以尋找其他有視覺圖像的介面 並盡可能將對話移到該資料夾

回應分支版本

每當你的執行要求收到 Google 助理的要求時，你就會 可以查詢下列介面 (例如 Google Home 或 Android 手機) 功能：

對話分支

您可以將 Dialogflow 意圖設為只在具有某些功能的情況下觸發，例如： 預先定義的 Dialogflow 背景資訊每次意圖相符時，Dialogflow 根據裝置的表面功能組合，自動產生背景資訊 可供使用。您可以指定一或多個這類背景資訊做為「輸入背景資訊」 適用於您的意圖這可讓您依據形態來觸發意圖。

舉例來說，如果您只想在有螢幕輸出的裝置上觸發意圖， 您可以將意圖的輸入背景資訊設為 actions_capability_screen_output。

可用的結構定義如下：

• actions_capability_audio_output - 裝置有喇叭。
• actions_capability_screen_output - 裝置有輸出顯示畫面。
• actions_capability_media_response_audio - 裝置支援播放媒體內容。
• actions_capability_web_browser：裝置支援網路瀏覽器。(這 功能目前不支援智慧螢幕。)

以下範例說明只會在有畫面的螢幕上觸發的意圖：

多介面對話

在動作執行流程的期間，您隨時可以檢查使用者是否有其他 具備特定功能的介面如果要求的其他途徑 即可將目前工作負載 建立新的對話視窗

注意： 如要轉移對話，系統只能根據具有 將 Android/iOS 手機當做目的地介面。

平面轉乘的流程如下：

1. 檢查使用者是否有可用的途徑

   在 Webhook 處理常式中，您可以查詢使用者是否有介面 特定功能可用的元件請注意，這個介面必須搭配 來源介面所使用的 Google 帳戶。

   Node.js

   const screenAvailable =
