谷歌的API-的dotnet客戶端的自動使用我有一串鑰匙：採用人機交互的所有文檔顯示認證客戶端ID，客戶端密鑰，API密鑰使用OAuth 2.0
不過。
如何在沒有用戶交互的情況下使用點網絡庫與Google API v3和AnalyticsService進行交互？如果我只是使用API密鑰，我會得到「Google.Apis.Requests.RequestError登錄必需」
沒有任何樣本可以在任何地方找到。
編輯：這是一個Google Analytics帳戶，我可以完全訪問它，用戶名，密碼，客戶端ID，客戶端密鑰，api /開發人員密鑰，所有內容。我只想每天沒有我的工具下載數據。
這是我的工作代碼，這是我通過批處理文件處理調用的控制檯應用程序。 我不是一個.Net開發人員，所以如果你看到有任何改進的地方讓我知道，這個代碼可能並不完美。 錯誤處理是最小的，因爲我不希望一個沒有殺一批
我使用註冊表來存儲訪問令牌和到期時間 也有在應用程序文件夾中的文件privatekey.p12的 帳戶是不用戶不是配置文件上的管理員。

請注意，服務帳號是用於服務器到服務器通信的，而**不適用於桌面應用程序，因爲您正在將您的*私人*密鑰文件暴露給該機器上的任何用戶/應用程序！ –
要爲用戶進行身份驗證，你仍然需要一個人的登錄信息和密碼，因此人機交互我相信ONC e用戶已經授權您的應用程序，它不再需要交互，但我並不完全熟悉google api。 –
我有用戶名和密碼。如果我必須在那裏每次手動授權訪問權限，如何創建實用程序以自動下載報告？ – pembo13
