c# - Azure 存储私有(private)容器 blob 到 MemoryStream

Question

我正在兜圈子，试图找出将文件从 Azure 存储私有(private)容器下载到 MemoryStream 的代码。

到目前为止我已经有了......

StorageCredentials storageCredentials = new StorageCredentials(*my StorageAccountName*, *my StorageAccountAccessKey*);
CloudStorageAccount storageAccount = new CloudStorageAccount(storageCredentials, true);

Uri blobUri = new Uri(featureFile.URL);
CloudBlockBlob blob = new CloudBlockBlob(blobUri);

MemoryStream mem = new MemoryStream();  
blob.DownloadToStream(mem);

最后一行出错...

The remote server returned an error: (404) Not Found.

但是，当容器不是私有(private)的时，它会正常工作而不会出现错误。

非常感谢任何帮助，谢谢。

请尝试以下代码:

StorageCredentials storageCredentials = new StorageCredentials(*my StorageAccountName*, *my StorageAccountAccessKey*);
CloudStorageAccount storageAccount = new CloudStorageAccount(storageCredentials, true);

Uri blobUri = new Uri(featureFile.URL);
CloudBlockBlob blob = new CloudBlockBlob(blobUri, storageCredentials);//added storageCredentials

MemoryStream mem = new MemoryStream();  
blob.DownloadToStream(mem);

由于容器具有Private ACL，因此需要对请求进行身份验证。使用this CloudBlockBlob 的构造函数负责处理这个问题。
