c# - AWS Glacier 上传 InvalidSignatureException C#

Question

我正在试用适用于 .NET 的 AWS 开发工具包，但遇到了以下问题。我无法使上传工作。

我想做的是:

class ArchiveUploadSingleOpLowLevel
{
    static string vaultName = "test001";
    static string archiveToUpload = "ver.txt"; //located in the same directory as the executable

    public static void Upload()
    {
        AmazonGlacierClient client;
        try
        {
            using (client = new AmazonGlacierClient(Amazon.RegionEndpoint.EUWest1))
            {
                Console.WriteLine("Uploading an archive.");
                string archiveId = UploadAnArchive(client);
                Console.WriteLine("Archive ID: {0}", archiveId);
            }
            Console.WriteLine("To continue, press Enter");
            Console.ReadKey();
        }
        catch (AmazonGlacierException e) { Console.WriteLine(e.Message); }
        catch (AmazonServiceException e) { Console.WriteLine(e.Message); }
        catch (Exception e) { Console.WriteLine(e.Message); }
        Console.WriteLine("To continue, press Enter");
        Console.ReadKey();
    }

    static string UploadAnArchive(AmazonGlacierClient client)
    {
        using (FileStream fileStream = new FileStream(archiveToUpload, FileMode.Open, FileAccess.Read))
        {
            string treeHash = TreeHashGenerator.CalculateTreeHash(fileStream);
            UploadArchiveRequest request = new UploadArchiveRequest()
            {
                VaultName = vaultName,
                Body = fileStream,
                Checksum = treeHash
            };
            UploadArchiveResponse response = client.UploadArchive(request);
            string archiveID = response.ArchiveId;
            return archiveID;
        }
    }
}

但我不断得到的结果是这个 AmazonGlacierException:

InvalidSignatureException

The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.

The Canonical String for this request should have been
'POST

The String-to-Sign should have been
'AWS4-HMAC-SHA256

现在明显的错误是我的配置中有错误的 AWSAccessKey 或 AWSSecretKey。我一遍又一遍地检查并重新复制/粘贴它们。文档和高级 API 没有提供太多关于签名方法的信息。

此外，我已在同一个应用程序中成功创建并列出了我的保管库。

因此，由于我在 win8.1(英文版)上运行 .Net 4.5、VS2012 SP3，因此我倾向于连接 TreeHashGenerator 的编码问题。

但这只是猜测。有人遇到过类似的问题吗？

问候马丁

Answer 1

我通过 Twitter 与 AWS SDK for .NET 团队交换了一些消息，他们发现了一个错误。此问题已在 SDK 2.0.6.1 版本中得到解决，现在可在 Nuget 中使用。
