我现在正在开发一个通过Mono在Linux实例上运行的C#应用程序。它需要在处理完图像后将图像存储在Google云端存储中。
我有auth凭据设置,.NET客户端库能够设置StorageService
对象(即找到JSON文件并验证所有内容)。当我尝试上传时,什么都没发生。所以在我的SetupConnection()
函数中,我试图查询我项目中的单个存储桶。我收到了这个错误:

这是我的设置代码:
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());
}
}
我以前能够让C#与GCS交谈,但那是我在Windows环境中使用Microsoft的.NET vm工作的时候。我之前做了一些研究,Mono处理CA与Microsoft的VM之间的关系可能存在一些问题。

您的问题通常来自未更新的根证书。
按照说明here更新根证书。
如果这没有帮助,那么您可以将代理设置为
ServicePointManager.ServerCertificateValidationCallback
并接受所有证书。如果可行,那么您就知道问题出在证书验证上,您可以尝试其他解决方案。 (我绝不会建议使用回调来接受生产中的所有证书,只是用它来调试你的问题。)

我解决了这个问题。
我使用的是Ubuntu附带的默认Mono版本,它已经过时了。我转而使用官方的Mono存储库: http://www.mono-project.com/docs/getting-started/install/linux/
然后安装了ca-certificates-mono
包。 (这里有更多细节:http://www.mono-project.com/docs/faq/security/)
