搭配 Google 試算表使用 Region Lookup API

這項產品或功能仍在實驗階段 (正式發布前)。 正式發布前的產品和功能僅提供有限支援，且正式發布前產品和功能的變更可能與其他正式發布前版本不相容。正式發布前產品/功能受到《Google 地圖平台服務專屬條款》規範。詳情請參閱推出階段說明。

您可以透過 Google 試算表使用 Apps Script 呼叫 Region Lookup API，離線查詢區域的地點 ID。如果資料集的輸入參數不明確，且可能會解析為多個地點 ID (例如「10 Main Street」)，或許就需要進行偵錯，在這種情況下，我們建議採取上述做法。這裡提供一個指令碼範例，包含下列函式：

• SearchRegionByLocation：搜尋邊界包含指定經緯度座標的地點。
• SearchRegionByAddress：搜尋邊界包含指定地址的地點。
• SearchRegionByPlaceId：搜尋包含指定地點 ID 的地點。
• LookupRegionByName：查詢包含指定名稱的地點。
• LookupRegionByUnitCode：查詢包含指定單位代碼的地點。

注意：Region Lookup API 和 Apps Script 程式碼為實驗功能版本。

區域查詢自訂函式

如要使用自訂函式，請先將自訂函式 .gs 指令碼程式碼，加進 Apps Script 指令碼編輯器。載入指令碼後，您可以呼叫這些函式，與呼叫任何其他試算表函式相同。指令碼會從儲存格取得輸入資料。透過試算表呼叫自訂函式，如下所示： =LookupRegionByName(A2,C2,D2,E2)

結果會輸出到函式所在儲存格和右側兩個儲存格中。如果有備選的地點 ID，這些地點 ID 的結果也會輸出到相鄰儲存格中。系統會提供驗證用的地點頁面連結，其中會顯示 Google 地圖中的區域名稱和多邊形。在下例中，如果將函式貼入儲存格 A1，結果會如下所示：

地點 ID	地點頁面網址	錯誤代碼
ChIJLQQwv4qBb0gRIMaY1COLDQU	https://www.google.com/maps/search/?api=1&query=%20&query_place_id=ChIJLQQwv4qBb0gRIMaY1COLDQU

在前例中，要求已順利完成，因此錯誤儲存格為空白。導致指令碼無法正確執行的錯誤 (例如省略有效的 API 金鑰)，會在函式所在儲存格中顯示為註解。

在 Apps Script 中加入自訂函式

1. 在 Google 試算表中開啟試算表。
2. 在選單項目中依序選取「擴充功能」>「Apps Script」。
3. 刪除指令碼編輯器中的任何程式碼。
4. 複製下例中的程式碼，並貼入指令碼編輯器。
5. 將 YOUR_API_KEY 換成未受限制的 API 金鑰，該金鑰應屬於已啟用 Region Lookup API 的專案。
6. 按一下頂端的「」。
