我一直在试图创建桶和使用他们的.NET SDK文件上传到Amazon S3。 我能够创造桶，并指定他们在欧盟地区创建。用于创建桶的code是如下

I have been trying to create buckets and upload files to Amazon S3 using their .net SDK. I am able to create the buckets and specify that they be created in the EU region. The code used to create the buckets is as below

PutBucketRequest request = new PutBucketRequest();
request.WithBucketName(bucketName)
       .WithBucketRegion(S3Region.EU);

client.PutBucket(request);

我再继续使用下面的code将文件上传到斗：

I then proceed to upload a file to the bucket using the following code:

PutObjectRequest request = new PutObjectRequest();
request.WithBucketName(bucketName)
    .WithCannedACL(S3CannedACL.PublicRead)
    .WithKey(remoteFileName)
    .WithInputStream(uploadFileStream);

文件上传code失败，错误达到最大重试次数。

The file upload code fails with the error "Maximum retry attempts reached."

任何人都可以让我知道还有什么我需要做，以便上传工作？

Can anyone let me know what else I need to be doing in order for the upload to work?

感谢。

编辑：尝试将文件上传到使用AWS管理控制台工作正常同一个桶

Trying to upload a file to the same bucket using the AWS Management Console works fine.

推荐答案

我发现这个问题，在最后。

I found the issue, at last.

当靶向在特定区域的桶，亚马逊S3客户对象将要被配置为使用特定端点。在code将配置端点是在客户端的建设者和创造是在下面的类的各个方法：

When targeting buckets in a specific region, the Amazon S3 client object will have to be configured to use a specific endpoint. The code to configure the endpoint is as in the constructor and creation of the client is in the individual methods of the class below:

public class AmazonS3Service : IAmazonS3Service 
{
     private AmazonS3 client;
     private string accessKeyID;
     private string secretAccessKeyID;
     private AmazonS3Config config;

     public AmazonS3Service()
     {
         accessKeyID = ConfigurationManager.AppSettings["AWSAccessKey"];
         secretAccessKeyID = ConfigurationManager.AppSettings["AWSSecretKey"];
         config = new AmazonS3Config();
         config.ServiceURL = ConfigurationManager.AppSettings["AWSEUEndPoint"];
      }

    public void CreateBucket(string bucketName)
    {
        using (client = Amazon.AWSClientFactory.CreateAmazonS3Client(accessKeyID, secretAccessKeyID, config))
        {
            try
            {
                PutBucketRequest request = new PutBucketRequest();
                request.WithBucketName(bucketName)
                       .WithBucketRegion(S3Region.EU);

                 client.PutBucket(request);
             }
             catch (AmazonS3Exception amazonS3Exception)
             {
                if (amazonS3Exception.ErrorCode != null && (amazonS3Exception.ErrorCode.Equals("InvalidAccessKeyId") || amazonS3Exception.ErrorCode.Equals("InvalidSecurity")))
                {
                //log exception - ("Please check the provided AWS Credentials.");
                }
                else
                {
                //log exception - ("An Error, number {0}, occurred when creating a bucket with the message '{1}", amazonS3Exception.ErrorCode, amazonS3Exception.Message);    
                }
            }
        }
    }

     public void UploadFile(string bucketName, Stream uploadFileStream, string remoteFileName)
    {
        using (client = Amazon.AWSClientFactory.CreateAmazonS3Client(accessKeyID, secretAccessKeyID, config))
        {
            try
            {
                PutObjectRequest request = new PutObjectRequest();
                request.WithBucketName(bucketName)
                    .WithCannedACL(S3CannedACL.PublicRead)
                    .WithKey(remoteFileName)
                    .WithInputStream(uploadFileStream);

                 using (S3Response response = client.PutObject(request))
                 {
                    WebHeaderCollection headers = response.Headers;
                    foreach (string key in headers.Keys)
                    {
                        //log headers ("Response Header: {0}, Value: {1}", key, headers.Get(key));
                    }
                }
            }
            catch (AmazonS3Exception amazonS3Exception)
            {
                if (amazonS3Exception.ErrorCode != null && (amazonS3Exception.ErrorCode.Equals("InvalidAccessKeyId") || amazonS3Exception.ErrorCode.Equals("InvalidSecurity")))
                {
                //log exception - ("Please check the provided AWS Credentials.");
                }
                else
                {
                //log exception -("An error occurred with the message '{0}' when writing an object", amazonS3Exception.Message);
                }
            }
        }
    }
 }
