我在获取共享访问签名以使用Storage 2.0时遇到问题.

我用的代码是:

if (blob.Exists())
{
    var expires = DateTime.UtcNow.AddMinutes(30);
    var sas = blob.GetSharedAccessSignature(new Microsoft.WindowsAzure.Storage.Blob.SharedAccessBlobPolicy
    {
        Permissions = Microsoft.WindowsAzure.Storage.Blob.SharedAccessBlobPermissions.Read,
        SharedAccessExpiryTime = expires
    });
    url = string.Concat(blob.Uri.AbsoluteUri, sas);
}
return url;

但是如果我调试会话并将URL粘贴到浏览器中,我会收到错误:

<Error>
  <Code>AuthenticationFailed</Code>
  <Message>
Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature. RequestId:c1a1dd2b-bf4a-4a6b-bab2-ab1cb9363d27 Time:2012-11-19T14:41:51.1254531Z

  </AuthenticationErrorDetail>
</Error>

有人可以帮忙吗？

更新:生成的URL如下所示:https: //storageaccountname.blob.core.windows.net/container/path/1356/pic.jpg？sv = 2012-02-12&se = …

我正在尝试为 blob 存储容器创建 SAS URL。我尝试了多个存储帐户和多种创建 SAS 的方法，当我在浏览器中测试 SAS URL 时，所有这些方法都给出了以下结果：

<Error>
<Code>AuthenticationFailed</Code>

我尝试了存储资源管理器（右键单击容器，获取 SAS，使用默认值单击确定）：

我尝试了旧的存储资源管理器：

我试过 PowerShell：

PS C:\Users\virklba> $context = New-AzureStorageContext -StorageAccountName msuscoreaprod
