无法通过Java代码访问S3。[但可以通过AWS CLI]

Question

我不能通过Java访问S3，但可以通过AWS CLI访问。

我正在使用来自适用于MINIO的AWS SDK的凭据

// import statements

public class S3Application {

    private static final AWSCredentials credentials;
    private static String bucketName;

    static {
        //put your accesskey and secretkey here
        credentials = new BasicAWSCredentials(
                "Q3AM3UQ867SPQQA43P2F",
                "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG"
        );
    }

    public static void main(String[] args) throws IOException {
        //set-up the client

        AmazonS3 s3Client = AmazonS3ClientBuilder
                .standard()
                .withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("http://play.min.io:9000","us-east-1"))
                .withCredentials(new AWSStaticCredentialsProvider(credentials))
                .build();

        AWSS3Service awsService = new AWSS3Service(s3Client);


    }

}

这是我上面提到的代码的日志。

您可能必须将PathStyle访问设置为true。https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/s3/AmazonS3Builder.html#withPathStyleAccessEnabled-java.lang.Boolean-

像这样的代码可能有效。

// import statements

public class S3Application {

    private static final AWSCredentials credentials;
    private static String bucketName;

    static {
        //put your accesskey and secretkey here
        credentials = new BasicAWSCredentials(
                "Q3AM3UQ867SPQQA43P2F",
                "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG"
        );
    }

    public static void main(String[] args) throws IOException {
        //set-up the client

        AmazonS3 s3Client = AmazonS3ClientBuilder
                .standard()
                .withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("http://play.min.io:9000","us-east-1"))
                .withCredentials(new AWSStaticCredentialsProvider(credentials))
                .withPathStyleAccessEnabled(true)
                .build();

        AWSS3Service awsService = new AWSS3Service(s3Client);


    }

}
