取得 Google API 用戶端 ID
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
Google 登入會管理 OAuth 2.0 流程和權杖生命週期，簡化與 Google API 的整合。使用者隨時可以撤銷應用程式的存取權。
如要在網站中整合 Google 第三方授權程式庫，您必須先建立用戶端 ID，才能呼叫第三方授權 API。
如要建立 Google Cloud 控制台專案和用戶端 ID，請按照操作說明取得 Google API 用戶端 ID。
設定專案時，請選取「網頁瀏覽器」用戶端類型，並指定應用程式的來源 URI。執行測試時，請將 http://localhost 和 http://localhost:<port_number> 新增至「已授權的 JavaScript 來源」欄位。
設定完成後，請記下建立的用戶端 ID。您需要用戶端 ID 才能完成後續步驟。(系統也會建立用戶端密鑰，但您只需要用於伺服器端作業)。
