Задача была отменена, исключение выдается, когда я пытаюсь вызвать fileTransferUtility.UploadAsync , чтобы загрузить файл i S3.Я использую dot net core 2.0 и пытаюсь загрузить файл на S3.Что я делаю неправильно в приведенном ниже коде?Это как-то связано с Timeout?Если да, то как установить время для S3 Bucket?или я должен установить некоторые свойства на S3 ведро?
Ниже код моего контроллера:
public class UploadController : Controller
{
private IHostingEnvironment _hostingEnvironment;
private AmazonS3Client _s3Client = new AmazonS3Client(RegionEndpoint.APSoutheast1);
private string _bucketName = "fileupload";//this is my Amazon Bucket name
private static string _bucketSubdirectory = String.Empty;
private string uploadWithKeyName = "testFile";
public UploadController(IHostingEnvironment environment)
{
_hostingEnvironment = environment;
}
[HttpPost("UploadExcelData")]
public async Task PostExcelData()
{
var files = Request.Form.Files;
var stringVal = Request.Form.Keys;
long size = files.Sum(f => f.Length);
foreach (var formFile in files)
{
if (formFile.Length > 0)
{
var filename = ContentDispositionHeaderValue
.Parse(formFile.ContentDisposition)
.FileName
.TrimStart().ToString();
filename = _hostingEnvironment.WebRootPath + $@"\uploads" + $@"\{formFile.FileName}";
size += formFile.Length;
using (var fs = System.IO.File.Create(filename))
{
formFile.CopyTo(fs);
fs.Flush();
}//these code snippets saves the uploaded files to the project directory
await UploadToS3(filename);//this is the method to upload saved file to S3
}
}
// return Ok();
}
public async Task UploadToS3(string filePath)
{
try
{
TransferUtility fileTransferUtility = new
TransferUtility(_s3Client);
string bucketName;
if (_bucketSubdirectory == "" || _bucketSubdirectory == null)
{
bucketName = _bucketName; //no subdirectory just bucket name
}
else
{ // subdirectory and bucket name
bucketName = _bucketName + @"/" + _bucketSubdirectory;
}
// 1. Upload a file, file name is used as the object key name.
await fileTransferUtility.UploadAsync(filePath, bucketName, uploadWithKeyName).ConfigureAwait(false);
Console.WriteLine("Upload 1 completed");
}
catch (AmazonS3Exception s3Exception)
{
Console.WriteLine(s3Exception.Message,
s3Exception.InnerException);
}
catch (Exception ex)
{
Console.WriteLine("Unknown error", ex.Message);
}
}
}
