AWS S3 Java SDK-拒绝访问

Question

我正在尝试使用AWS开发工具包访问存储桶及其所有对象，但是在运行代码时，出现错误，线程“ main”中出现异常
com.amazonaws.services.s3.model.AmazonS3Exception: Access Denied (Service: Amazon S3; Status Code: 403; Error Code: AccessDenied; Request ID: X), S3 Extended Request ID: Y=

请提出建议，尽管我已经对存储桶采取了以下所有许可，但我缺少的地方以及为什么发生拒绝访问错误：

s3:GetObject
s3:GetObjectVersion
s3:GetObjectAcl
s3:GetBucketAcl
s3:GetBucketCORS
s3:GetBucketLocation
s3:GetBucketLogging
s3:ListBucket
s3:ListBucketVersions
s3:ListBucketMultipartUploads
s3:GetObjectTorrent
s3:GetObjectVersionAcl

代码如下：

AWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
ClientConfiguration clientConfig = new ClientConfiguration();
clientConfig.setProtocol(Protocol.HTTP);
AmazonS3 conn = new AmazonS3Client(credentials, clientConfig);
conn.setEndpoint(bucketName);
Bucket bucket = conn.createBucket(bucketName);
ObjectListing objects = conn.listObjects(bucket.getName());
do {
    for (S3ObjectSummary objectSummary : objects.getObjectSummaries()) {
            System.out.println(objectSummary.getKey() + "\t" +
                    objectSummary.getSize() + "\t" +
                    StringUtils.fromDate(objectSummary.getLastModified()));
    }
    objects = conn.listNextBatchOfObjects(objects);
} while (objects.isTruncated());

现在问题已解决。代码存在以下问题：

1. 终点不正确，应该有一个正确的终点。
2. 没有足够的权限授予该存储桶。在AWS开发工具包中使用存储桶之前，应获取完整权限列表。

下面是正确的代码

AWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
ClientConfiguration clientConfig = new ClientConfiguration();
clientConfig.setProtocol(Protocol.HTTP);
AmazonS3 conn = new AmazonS3Client(credentials, clientConfig);
conn.setEndpoint("correct end point");
Bucket bucket = conn.createBucket(bucketName);
ObjectListing objects = conn.listObjects(bucket.getName());
do {
    for (S3ObjectSummary objectSummary : objects.getObjectSummaries()) {
            System.out.println(objectSummary.getKey() + "\t" +
                    objectSummary.getSize() + "\t" +
                    StringUtils.fromDate(objectSummary.getLastModified()));
    }
    objects = conn.listNextBatchOfObjects(objects);
} while (objects.isTruncated());
