azure - Windows Azure 存储版本升级到 > 4 会导致 "The remote server returned an error: (400) Bad Request."

Question

我在通过 nuget 包管理器升级到 4.0.1.0 后开始遇到这种情况。然后我升级到 4.1.0.0 希望这可能是一个错误，但仍然是同样的问题。

我使用的是基于云的azure存储，而不是模拟器。

我之前使用的是 3.0.3.0，它可以工作，当我切换到这个版本时仍然可以工作。

这是整个方法(基本上是将 blob 从一个容器复制到另一个容器)

public string CopyBlobs(string blobPath)
    {
        var storageAccount = new CloudStorageAccount(new StorageCredentials(_storageAccountName, _storageAccountKey), true);
        var cloudBlobClient = storageAccount.CreateCloudBlobClient();
        var destContainer = cloudBlobClient.GetContainerReference(cloudBlobClient.BaseUri + _publishBlobContainer);

        destContainer.CreateIfNotExists();
        BlobContainerPermissions containerPermissions = new BlobContainerPermissions(); 
        containerPermissions.PublicAccess = BlobContainerPublicAccessType.Blob; 
        destContainer.SetPermissions(containerPermissions);  
        var src = GetSasUrl(blobPath);
        CloudBlockBlob srcBlob = new CloudBlockBlob(new Uri(src));
        CloudBlockBlob destBlob;
        destBlob = destContainer.GetBlockBlobReference(srcBlob.Name); 
        destBlob.StartCopyFromBlob(srcBlob);
        return destBlob.StorageUri.PrimaryUri.ToString();
    }

这就是抛出异常的地方:

destContainer.CreateIfNotExists();

更新:当我调用上面的方法时，Fiddler 会记录。

Answer 1

请更改以下代码行:

var destContainer = cloudBlobClient.GetContainerReference(cloudBlobClient.BaseUri + _publishBlobContainer);

至

var destContainer = cloudBlobClient.GetContainerReference(_publishBlobContainer);

这应该可以解决问题。
