Azure 媒体服务：尝试 6 次后重试失败。（操作被取消。）

Viv*_*rma 3 .net c# azure azure-media-services

要了解 Azure 媒体服务，我正在关注教程：使用媒体服务 v3 上传、编码和流式传输视频。但目前卡在本文中给出的代码UploadEncodeAndStreamFilesRetry failed after 6 tries. (The operation was canceled.)在文件上传期间抛出异常await blob.UploadAsync(fileToUpload);。

private static async Task<Asset> CreateInputAssetAsync(
        IAzureMediaServicesClient client,
        string resourceGroupName,
        string accountName,
        string assetName,
        string fileToUpload)
    {
        // In this example, we are assuming that the asset name is unique.
        //
        // If you already have an asset with the desired name, use the Assets.Get method
        // to get the existing asset. In Media Services v3, the Get method on entities returns null 
        // if the entity doesn't exist (a case-insensitive check on the name).

        // Call Media Services API to create an Asset.
        // This method creates a container in storage for the Asset.
        // The files (blobs) associated with the asset will be stored in this container.
        Asset asset = await client.Assets.CreateOrUpdateAsync(resourceGroupName, accountName, assetName, new Asset());

        // Use Media Services API to get back a response that contains
        // SAS URL for the Asset container into which to upload blobs.
        // That is where you would specify read-write permissions 
        // and the exparation time for the SAS URL.
        var response = await client.Assets.ListContainerSasAsync(
            resourceGroupName,
            accountName,
            assetName,
            permissions: AssetContainerPermission.ReadWrite,
            expiryTime: DateTime.UtcNow.AddHours(4).ToUniversalTime());

        var sasUri = new Uri(response.AssetContainerSasUrls.First());

        // Use Storage API to get a reference to the Asset container
        // that was created by calling Asset's CreateOrUpdate method.  
        BlobContainerClient container = new BlobContainerClient(sasUri);
        BlobClient blob = container.GetBlobClient(Path.GetFileName(fileToUpload));

        // Use Strorage API to upload the file into the container in storage.
        await blob.UploadAsync(fileToUpload);

        return asset;

还有其他人遇到过这样的问题吗？如果是，您能帮助一下可能导致此问题的原因吗？我是否缺少导致此问题的权限？

当您使用低带宽上传网络时，似乎会发生这种情况。你可以加

BlobUploadOptions upOptions = new BlobUploadOptions
        {
            TransferOptions = new StorageTransferOptions
            {
                MaximumTransferSize = 4 * 1024 * 1024,
                InitialTransferSize = 4 * 1024 * 1024
            }
        };
        // Use Strorage API to upload the file into the container in storage.
        await blob.UploadAsync(file,upOptions);

这将改变块大小并使其在较低带宽下工作。

我同意杰森的回答，只是做了一些修改。

首先我会删除无限的 while 循环。其次，参考 github 问题线程，我认为最重要的一点是，在构造 或时BlobClientOptions应该传递。然后指定运输。正如线程 Tweaking Transport in BlobClientOptions中提到的BlobContainerClientBlobClient

new BlobClientOptions
{
    Transport = new HttpClientTransport(
        new HttpClient { Timeout = TimeSpan.FromSeconds(102) })
};

我看到杰森的评论中的上述内容被注释掉了，但这将是解决问题的一个组成部分。

您还可以考虑延长重试期限，此请求需要超过 6 次尝试才能成功连接。

new BlobClientOptions // or whatever options class suitable for your client
{
    Transport = new HttpClientTransport( new HttpClient { Timeout = Timeout.InfiniteTimeSpan } ),
    Retry = { NetworkTimeout = Timeout.InfiniteTimeSpan }
}
