如何从 AWS S3 上传器获取响应

Question

我正在使用 AWS S3 来存储文件。 我能够上传和删除文件。 唯一的问题是上传大文件时，如何知道上传了多少，我需要像进度条一样实现。

请帮我做。

 IAmazonS3 client = new AmazonS3Client(RegionEndpoint.USEast2);
            TransferUtility utility = new TransferUtility(client);
            TransferUtilityUploadRequest request = new TransferUtilityUploadRequest();
if (subDirectoryInBucket == "" || subDirectoryInBucket == null)
            {
                request.BucketName = bucketName; //no subdirectory just bucket name  
            }
            else
            {   // subdirectory and bucket name  
                request.BucketName = bucketName + @"/" + subDirectoryInBucket;
            }
            request.Key = RandomString()+ Path.GetExtension(e.File.FileName); //file name up in S3  
            request.InputStream = e.File.InputStream;
            request.CannedACL=S3CannedACL.PublicRead;
            utility.Upload(request); //commensing the transfer 

我正在使用此代码。

您好，您可以调用 TransferUtilityUploadRequest 方法，

下面是例子，你也可以参考这个link！希望这会有所帮助

using System;
using System.Collections.Specialized;
using System.Configuration;
using Amazon.S3;
using Amazon.S3.Transfer;


namespace s3.amazon.com.docsamples
{
    class TrackMPUUsingHighLevelAPI
    {
        static string existingBucketName = "*** Provide bucket name ***";
        static string keyName            = "*** Provide key name ***";
        static string filePath           = "*** Provide file to upload ***";

    static void Main(string[] args)
        {
        try
        {
            TransferUtility fileTransferUtility =
                new TransferUtility(new AmazonS3Client(Amazon.RegionEndpoint.USEast1));

            // Use TransferUtilityUploadRequest to configure options.
            // In this example we subscribe to an event.
            TransferUtilityUploadRequest uploadRequest =
                new TransferUtilityUploadRequest
                {
                    BucketName = existingBucketName,
                    FilePath = filePath, 
                    Key = keyName
                };

            uploadRequest.UploadProgressEvent +=
                new EventHandler<UploadProgressArgs>
                    (uploadRequest_UploadPartProgressEvent);

            fileTransferUtility.Upload(uploadRequest);
            Console.WriteLine("Upload completed");
        }

        catch (AmazonS3Exception e)
        {
            Console.WriteLine(e.Message, e.InnerException);
        }
    }

    static void uploadRequest_UploadPartProgressEvent(
        object sender, UploadProgressArgs e)
    {
        // Process event.
        Console.WriteLine("{0}/{1}", e.TransferredBytes, e.TotalBytes);
    }
}
}
