認識這項解決方案

共用休假日曆是協助團隊協作的絕佳工具，可讓任何人一目瞭然誰不在辦公室。這項解決方案可讓您查看同事何時不在辦公室，不必手動輸入。

休假日曆範例

運作方式

這項解決方案會根據 Google 群組中每個人的日曆，填入共用的假期日曆。使用者預約休假時，會在個人 Google 日曆中新增活動，並使用「休假」或「不在辦公室」等關鍵字。

每小時，指令碼會掃描群組成員的日曆，並將適當的活動同步至共用日曆。您可以變更指令碼掃描新事件的頻率。

這項解決方案只會存取同事透過隱私權設定向您顯示的日曆活動。

Apps Script 服務

這項解決方案會使用下列服務：

群組服務：決定 Google 群組的成員。
日曆進階服務：提供 Google 日曆 API 的存取權，並在群組成員的日曆中搜尋活動。

必要條件

如要使用這個範例，您必須符合下列先決條件：

Google 帳戶 (Google Workspace 帳戶可能需要管理員核准)。
可連上網際網路的網路瀏覽器。

設定指令碼

建立團隊休假日曆

開啟 Google 日曆。
建立名為「團隊假期」的新日曆。
在日曆設定的「整合日曆」下方，複製「日曆 ID」。

建立 Apps Script 專案

按一下下列按鈕，開啟「Vacation Calendar」Apps Script 專案。
開啟專案
按一下「總覽」。
在總覽頁面中，按一下「建立副本」圖示。
在複製的 Apps Script 專案中，將變數 TEAM_CALENDAR_ID 設為您先前建立的日曆 ID。
將變數 GROUP_EMAIL 設為包含團隊成員的 Google 群組電子郵件地址。
按一下「服務」旁的「新增服務」圖示。
選取「Google Calendar API」，然後按一下「新增」。

執行指令碼

在複製的 Apps Script 專案中，從函式下拉式選單選取「設定」。
按一下「執行」。
出現提示訊息時，請授權執行指令碼。如果 OAuth 同意畫面顯示「這個應用程式未經驗證」警告，請依序選取「進階」>「前往『{專案名稱}』(不安全)」，繼續操作。
完成後，請返回日曆，確認「Team Vacations」日曆已填入活動。
