在C＃/單聲道，無法與谷歌雲存儲

Question

我正在開發一個C＃應用程序，現在通過Mono在Linux實例上運行。它需要將圖像存儲在Google雲端存儲中。

我有auth憑據設置，.NET客戶端庫能夠設置StorageService對象（即查找JSON文件並驗證所有內容）。當我嘗試上傳時，什麼都沒有發生。所以在我的SetupConnection()函數中，我試圖查詢我的項目中的單個存儲桶。我得到這個錯誤：

這是我的設置代碼：

public static void SetupGCSConnection() 
{ 
    var credentials = Google.Apis.Auth.OAuth2.GoogleCredential.GetApplicationDefaultAsync().Result; 

    if (credentials.IsCreateScopedRequired) 
     credentials = credentials.CreateScoped(new[] { StorageService.Scope.DevstorageFullControl }); 

    var serviceInitializer = new BaseClientService.Initializer() 
    { 
     ApplicationName = "MyApp", 
     HttpClientInitializer = credentials 
    }; 

    storage = new StorageService(serviceInitializer); 

    // Error is thrown here 
    var buckets = storage.Buckets.List(Config.GoogleProjectID).Execute(); 
    foreach (var b in buckets.Items) { 
     Console.WriteLine(b.ToString()); 
    } 
} 

我已經能夠得到C＃交談GCS之前，但當時我在Windows環境下工作，與微軟的.NET虛擬機。我之前做了一些研究，Mono處理CA與微軟VM相比，可能存在一些問題。

Answer 1

您的問題通常來自根證書未被更新。

按照說明here更新您的根證書。

如果沒有幫助，那麼你可以委託設置爲

ServicePointManager.ServerCertificateValidationCallback 

並接受所有證書。如果有效，那麼您知道問題出在證書驗證上，您可以嘗試其他解決方案。 （我永遠不會建議使用回調來接受生產中的所有證書，只是用它來調試你的問題）。

Answer 2

我修復了這個問題。

我使用的是Ubuntu自帶的默認Mono版本，它已過期。我轉而使用官方的Mono軟件倉庫： http://www.mono-project.com/docs/getting-started/install/linux/

然後再安裝ca-certificates-mono包。 （更多細節請點擊：http://www.mono-project.com/docs/faq/security/）
