如何獲取訪問令牌以獲取谷歌分析數據？

Question

我正在使用 Google Analytics 來獲取我網站的數據。 我已經在查詢資源管理器上測試了查詢。 但是我無法使用 OAuth 在代碼中實現它。 我需要一個訪問令牌來運行我的查詢，但我的問題是我無法獲得訪問令牌。 任何人都可以指導我完成這個。 誰能解釋谷歌開發者控制台與分析帳戶之間的關系。 請參考一些實現文檔。

Answer 1

假設這是您要訪問的自己的數據，並且您可以訪問 Google Analytics 帳戶網站。 我建議您使用服務帳戶。 你好分析 API Java

谷歌開發者控制台是你向谷歌注冊你的應用程序的地方，它與你的谷歌分析帳戶沒有任何關系。

我再次建議您使用服務帳戶並在 Google Developer Console 上創建服務帳戶憑據。 將服務帳戶電子郵件地址添加為帳戶級別的 google 分析管理部分的用戶，授予它讀取權限，它必須在帳戶級別。 這將允許服務帳戶讀取您的谷歌分析數據。
