Azure blob 批量删除西里尔字符

Question

我可以使用 Azure.Storage.Blobs 12.9.1 上传包含西里尔字符的 blob，但无法使用 Azure.Storage.Blobs.Batch 12.6.0 批量删除它们。

考虑以下 blob 名称：здраве-и-красота-от-природатаjpg--xfgqfvhj.axp.webp 和代码：

var blobsToBeDeleted = new List<Uri>();
blobsToBeDeleted.Add(new Uri("azure-storage-address/container/здраве-и-красота-от-природатаjpg--xfgqfvhj.axp.webp"));
blobsToBeDeleted.Add(new Uri("azure-storage-address/container/thumbs/здраве-и-красота-от-природатаjpg--xfgqfvhj.axp.webp"));
await batchClient.DeleteBlobsAsync(blobsToBeDeleted);

在 Azure 上运行后，响应是：

Azure.RequestFailedException
{"Invalid response\r\nStatus: 202 (Accepted)\r\n\r\nHeaders:\r\nTransfer-Encoding: chunked\r\nServer: Windows-Azure-Blob/1.0,Microsoft-HTTPAPI/2.0\r\nx-ms-request-id: 9255671d-301e-008e-1a4a-797e59000000\r\nx-ms-version: 2020-08-04\r\nx-ms-client-request-id: ad39b21f-aad7-484e-8121-a707a318088e\r\nDate: Thu, 15 Jul 2021 07:24:29 GMT\r\nContent-Type: multipart/mixed; boundary=batchresponse_7c0d302a-8ee6-4d48-aac1-d973904338c3\r\n"}  Azure.RequestFailedException
{"Expected 2 responses for the batch request, not 1."}
Status 202

其他名称结构同上，代码同上，但只包含拉丁字符的文件删除成功。

new Uri() 似乎可以正确转义字符，并且由于 BlobBatchClient.DeleteBlobsAsync 方法接受 IEnumerable<Uri> 我真的不明白问题出在哪里。

对此有什么想法吗？

编辑

这是一个已知问题，已经修复，将在下一个版本中发布 - https://github.com/Azure/azure-sdk-for-net/issues/22329

Answer 1

请尝试以下方法。这是一个有点复杂的方法，SDK 当然可以改进但它可以工作：

private static string connectionString =
    "DefaultEndpointsProtocol=https;AccountName=account-name;AccountKey=account-key==";
private static string containerName = "container-name";

static async Task Main(string[] args)
{
    BlobServiceClient blobServiceClient = new BlobServiceClient(connectionString);
    BlobBatchClient batchClient = new BlobBatchClient(blobServiceClient);
    
    List<string> blobNames = new List<string>()
    {
        "здраве-и-красота-от-природатаjpg--xfgqfvhj.axp.webp",
        "thumbs/здраве-и-красота-от-природатаjpg--xfgqfvhj.axp.webp"
    };
    BlobContainerClient containerClient = blobServiceClient.GetBlobContainerClient(containerName);
    List<BlobClient> blobClients = blobNames.Select(b => containerClient.GetBlobClient(b)).ToList();
    List<Uri> blobsToBeDeleted = blobClients.Select(b => new Uri(Uri.EscapeUriString(b.Uri.AbsoluteUri))).ToList();
    await batchClient.DeleteBlobsAsync(blobsToBeDeleted);
}

更新

所以我需要在我的一个项目中实现这个功能，我找到了另一种实现这个功能的方法，它有点不那么复杂。我想我也会在这里分享。这是我最终实现的代码：

private static string connectionString =
    "DefaultEndpointsProtocol=https;AccountName=account-name;AccountKey=account-key==";
private static string containerName = "container-name";
static async Task Main(string[] args)
{
    BlobServiceClient blobServiceClient = new BlobServiceClient(connectionString);
    BlobBatchClient batchClient = new BlobBatchClient(blobServiceClient);
    
    List<string> blobNames = new List<string>()
    {
        HttpUtility.UrlEncode("здраве-и-красота-от-природатаjpg--xfgqfvhj.axp.pdf"),
        HttpUtility.UrlEncode("здраве-и-красота-от-природатаjpg--xfgqfvhj.pdf")
    };
    BlobBatch batch = new BlobBatch(batchClient);
    foreach (var blobName in blobNames)
    {
        batch.DeleteBlob(containerName, blobName, DeleteSnapshotsOption.IncludeSnapshots);
    }

    await batchClient.SubmitBatchAsync(batch);
}
