我在尝试使用AWS S3高级API客户端时遇到了问题。我使用的代码与AWS示例文档(www.example.com)中描述的代码几乎相同https://github.com/awsdocs/aws-doc-sdk-examples/blob/main/dotnetv3/S3/TrackMPUUsingHighLevelAPIExample/TrackMPUUsingHighLevelAPI.cs#L48
唯一不同的是客户端创建,因为我是出于测试目的而手动设置的:

var configuration = new AmazonS3Config
{
   ForcePathStyle = true,
   ServiceURL = "URL",
};
var credentials = new BasicAWSCredentials("ACCESS_KEY", "SECRET");
IAmazonS3 client = new AmazonS3Client(credentials, configuration);

然而,当插入文件时,我得到以下异常:

Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1]
      An unhandled exception has occurred while executing the request.
      Amazon.S3.AmazonS3Exception: Transfering payloads in multiple chunks using aws-chunked is not supported.
       ---> Amazon.Runtime.Internal.HttpErrorResponseException: Exception of type 'Amazon.Runtime.Internal.HttpErrorResponseException' was thrown.
         at Amazon.Runtime.HttpWebRequestMessage.GetResponseAsync(CancellationToken cancellationToken)
         at Amazon.Runtime.Internal.HttpHandler`1.InvokeAsync[T](IExecutionContext executionContext)
         at Amazon.Runtime.Internal.RedirectHandler.InvokeAsync[T](IExecutionContext executionContext)
         at Amazon.Runtime.Internal.Unmarshaller.InvokeAsync[T](IExecutionContext executionContext)
         at Amazon.S3.Internal.AmazonS3ResponseHandler.InvokeAsync[T](IExecutionContext executionContext)
         at Amazon.Runtime.Internal.ErrorHandler.InvokeAsync[T](IExecutionContext executionContext)

我没有在任何地方显式地设置aws-chunked,所以我很困惑我所面临的确切问题是什么。

我试过使用PutObjectRequest以下列方式上传文件,一切都为我工作:

fs.Seek(0, SeekOrigin.Begin);
 var uploadRequest = new PutObjectRequest
 {
    InputStream = fs,
    Key = outputFileName,
    BucketName = bucketName,
    UseChunkEncoding = false,
 };
 await _client.PutObjectAsync(uploadRequest);

我忘了说我使用的是其他供应商(不是AWS)提供的存储,它支持AWS S3 API。不幸的是,目前它确实不支持分块上传。
