スカラのAmazon S3に接続できません。 Pythonの接続はうまく動作しますが、Scalaでは403 Forbiddenのレスポンスが得られます

Question

またポート番号もありますが、設定する場所が見つかりませんでした。この問題を解決するにはどうすればよいですか？ Pythonの "boto"クライアントを通して私は正常に私のサービスに接続しましたが、Scalaでは常に禁止メッセージを返します。ここで

object a extends App{ 

     import com.amazonaws.auth.BasicAWSCredentials 

     val accessKey = "myAccessKey" 
     val secretKey = "mySecretKey" 
     val credentials = new BasicAWSCredentials(accessKey, secretKey) 

     import com.amazonaws.services.s3.AmazonS3Client 

     val s3client = new AmazonS3Client(credentials) 

     s3client.setEndpoint("address") 

     val s3object = s3client.getObject("myBucket", "file.txt") 

     println(s3object.getKey, s3object.getObjectMetadata.getLastModified) 
    } 

はエラーログです：

AWS SDKは、何らかの形で使用して思いとどまらendpoint（JavaDoc）：非標準サービスのエンドポイントを使用している場合

は

のみこれを使用します - クライアントを設定するための推奨されるアプローチは、{@link #withRegion（String）}

代わりにwithRegionを使用してください。

import com.amazonaws.auth.{AWSStaticCredentialsProvider, BasicAWSCredentials} 
import com.amazonaws.regions.Regions 
import com.amazonaws.services.s3.AmazonS3Client 

AmazonS3Client.builder() 
    .withCredentials(new AWSStaticCredentialsProvider(
    new BasicAWSCredentials("accessKey", "secretKey"))) 
    .withRegion(Regions.EU_WEST_1).build()
