如何使用 AWS Java SDK V2 公開 S3 object？

Question

如何通過 AWS Java SDK V2.2.41 公開 S3 object？

Specifically, what API methods via the Java AWS SDK V2 can be used to make an Object public when it's being uploaded or we make an existing uploaded object publicly readable?

Answer 1

您可以使用 CannedAccessControlList.PublicRead 屬性通過 AWS Java SDK 創建公共對象。

s3client.putObject(putObjectRequest.withCannedAcl(CannedAccessControlList.PublicRead))

Answer 2

好吧，終於找到了答案：我們可以使用

.acl(ObjectCannedACL.PUBLIC_READ)

使用 PutObjectRequest 如下：

    PutObjectResponse putObjRes = s3Client.putObject(
            PutObjectRequest.builder()
                    .bucket("bucket")
                    .key("key)
                    .acl(ObjectCannedACL.PUBLIC_READ)
                    .build(), RequestBody.fromFile(<file>));
