c# - 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但随后无法使用 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 上运行此命令后，响应为:

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

具有名称结构并使用与上述相同的代码但仅包含拉丁字符的其他文件已成功删除。

new Uri()似乎正确地转义字符，因为 BlobBatchClient.DeleteBlobsAsync方法接受 IEnumerable<Uri>我实在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，已修复并将在下一版本中发布 - https://github.com/Azure/azure-sdk-for-net/issues/22329

请尝试以下操作。这是一个有点复杂的方法，SDK 当然可以改进，但它确实有效:

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

因此，我需要在我的一个项目中实现此功能，并且我找到了一种实现此功能的替代方法，该方法稍微简单一些。我想我也会在这里分享这一点。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);
}
