使用适用于 .NET 的 AWS 开发工具包 (高级别 API) 跟踪到 S3 存储桶的分段上传的进度

以下 C# 示例使用 TransferUtility 类将文件上传到 S3 存储桶并跟踪上传的进度。有关示例与特定版本的适用于 .NET 的 AWS 开发工具包的兼容性的信息以及有关创建和测试有效示例的说明,请参阅运行 Amazon S3 .NET 代码示例

using Amazon.S3; using Amazon.S3.Transfer; using System; using System.Threading.Tasks; namespace Amazon.DocSamples.S3 { class TrackMPUUsingHighLevelAPITest { private const string bucketName = "*** provide the bucket name ***"; private const string keyName = "*** provide the name for the uploaded object ***"; private const string filePath = " *** provide the full path name of the file to upload **"; // Specify your bucket region (an example region is shown). private static readonly RegionEndpoint bucketRegion = RegionEndpoint.USWest2; private static IAmazonS3 s3Client; public static void Main() { s3Client = new AmazonS3Client(bucketRegion); TrackMPUAsync().Wait(); } private static async Task TrackMPUAsync() { try { var fileTransferUtility = new TransferUtility(s3Client); // Use TransferUtilityUploadRequest to configure options. // In this example we subscribe to an event. var uploadRequest = new TransferUtilityUploadRequest { BucketName = bucketName, FilePath = filePath, Key = keyName }; uploadRequest.UploadProgressEvent += new EventHandler<UploadProgressArgs> (uploadRequest_UploadPartProgressEvent); await fileTransferUtility.UploadAsync(uploadRequest); Console.WriteLine("Upload completed"); } catch (AmazonS3Exception e) { Console.WriteLine("Error encountered on server. Message:'{0}' when writing an object", e.Message); } catch (Exception e) { Console.WriteLine("Unknown encountered on server. Message:'{0}' when writing an object", e.Message); } } static void uploadRequest_UploadPartProgressEvent(object sender, UploadProgressArgs e) { // Process event. Console.WriteLine("{0}/{1}", e.TransferredBytes, e.TotalBytes); } } }
