问题


I am using the Azure Blob storage client library v12 for .NET i used this guide to setup https://docs.microsoft.com/en-us/azure/storage/blobs/storage-quickstart-blobs-dotnet

It is all working fine on internet connections with fast upload speeds but once I try run this program on a site with upload speed on 1Mbps it doesnt work i have now been able to replicate this issue but using software on my computer to restrict the upload speed in my dev environment when i set the upload speed to 1Mbps it fails to upload the file after about 10 minutes of trying

The file is about 15Mb of json

15Mb file should upload in about 2 - 3 minutes on 1Mbps i would think

This is the code i am trying to use as i said when tested on 30Mbps upload connection it all working fine

public static async Task UploadData(string json)
 {


BlobClientOptions MyBlobClientOptions = new BlobClientOptions
            {
                Transport = new HttpClientTransport(
                    new HttpClient { Timeout = TimeSpan.FromSeconds(600) })
            };

 //Setup Azure BlobServiceClient
            string datetime = DateTimeOffset.Now.ToString("yyyyMMddHHmmss");
            string AzureConnectionString = _iconfiguration.GetConnectionString("AzureStorage");
            BlobServiceClient blobServiceClient = new BlobServiceClient(AzureConnectionString,MyBlobClientOptions);

            string localFilePath = $"{TempDirPath}data{datetime}.json";

            // Write text to the file
            await File.WriteAllTextAsync(localFilePath, json);
            string localFileName = $"UPLOAD_SPEED_TEST/data{datetime}.json";


            // Get a reference to a blob
            BlobContainerClient containerClient = blobServiceClient.GetBlobContainerClient("data");
            BlobClient blobClient = containerClient.GetBlobClient(localFileName);

            _logger.LogInformation("Uploading to Blob storage as blob:\n\t {0}\n", blobClient.Uri);

     try
        {

            //Test this Option to see if it would fix upload issue on slow connections
            StorageTransferOptions transferOptions = new StorageTransferOptions();
            transferOptions.MaximumConcurrency = 2;

            // Open the file and upload its data
            using FileStream uploadFileStream = File.OpenRead(localFilePath);
            uploadFileStream.Position = 0;
            
            // Upload file to Azure Blob Storage
            blobClient.Upload(uploadFileStream, transferOptions: transferOptions);
            _logger.LogInformation("UPLOAD COMPLETE");
            uploadFileStream.Close();

        } 
        catch (Exception ex)
        {
            //Error upload Failed
            _logger.LogInformation("UPLOAD ERROR" + ex.ToString());
        }
}

回答1:


As Gaurav said, you need to split the file in blocks and read those blocks and upload them using StageBlock method. Once all blocks are uploaded, you call CommitBlockList method to commit those blocks and create the blob.

Please refer to this SO thread.




回答2:


I was getting this same issue exception when trying to upload a 60MB file over a 4Mbps connection.:

System.AggregateException: Retry failed after 6 tries.

I did the following to get it working for me:

  1. Set the Retry timeout as well as the Transport timeout (thanks to this GitHub post for that idea):
var blobClientOptions = new BlobClientOptions
{
    Transport = new HttpClientTransport(new HttpClient { Timeout = Timeout.InfiniteTimeSpan }),
    Retry = { NetworkTimeout = Timeout.InfiniteTimeSpan }
};

See this answer for more on setting the Retry options.

  1. I also overwrote the cancellation token in the hope of stopping the code calling my function cancelling it:
await blobClient.UploadAsync(
    content: uploadFileStream, httpHeaders: 
    cancellationToken: CancellationToken.None);
