Question

我需要从 S3 存储桶下载对象，我有以下信息可以访问 S3 存储桶。

访问密钥、秘密密钥和存储桶端点。没有区域名称。

我使用 minio 包访问存储桶，并且能够使用以下代码访问它：

  public void getS3BucketObject() throws IOException, NoSuchAlgorithmException,
            InvalidKeyException, ServerException, InsufficientDataException, InternalException, InvalidResponseException,
            XmlParserException, ErrorResponseException {

        //creating minioClient to access S3 bucket
        minioClient =
                MinioClient.builder()
                        .endpoint(s3BucketEndpoint)
                        .credentials(s3BucketAccessKey, s3BucketSecretKey)
                        .build();

        //check for bucket existance
        boolean found =
                minioClient.bucketExists(BucketExistsArgs.builder().bucket(s3BucketName).build());
        if (!found) {
           System.out.println("Bucket doesn't exist ");
        } else {
          System.out.println("Bucket exists ");
        }
    }

但是，我确实需要使用 AWS SDK 而不是 minio，但我不确定，因为我没有区域信息，也不确定如何在配置设置中传递端点，尽管我在下面尝试过。

 final BasicAWSCredentials credentials = new BasicAWSCredentials(s3BucketAccessKey, s3BucketSecretKey);
            final AmazonS3 s3client = AmazonS3ClientBuilder.standard()
                                                    .withCredentials(new AWSStaticCredentialsProvider(credentials));
                            
            boolean found = s3client.doesBucketExistV2(s3BucketName);

            if (found){
                System.out.println("The bucket is available ");
            }else {
                System.out.println("The bucket doesn't exist");
            }

您是否在使用构建器创建 s3client 时尝试使用 withRegion(AWS_S3_REGION) 选项？

AmazonS3 s3client = AmazonS3ClientBuilder.standard()
 .withRegion("us-east-1") 
 .build();

参考。 https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/s3/AmazonS3ClientBuilder.html

AmazonS3ClientBuilder.defaultClient() fails to account for region?

在不提供区域名称的情况下连接到 S3 存储桶
