我正在尝试将 EC2 快照从一个区域移动到另一个区域。

创建基本 Ec2 快照副本并将其复制到第二个区域时，我得到错误协议不能为空。当您到达需要主机的代码点时，主机似乎也是空的。据我了解，在复制未加密的快照时，我不需要提供协议（http/https）或主机详细信息。AWS 代码似乎应该在幕后执行此操作。

在我的脑海中，这似乎是一个 aws 问题，但是对于 Java V2 的 AWS 开发工具包还没有太多反馈，因为我在这里和 github 都检查过。

程序异常： java.lang.NullPointerException：协议不能为空

我尝试将destinationRegion 添加到构建器，但这也会导致相同的错误。

执行环境是 Amazon Java 11.0.3 我已经尝试使用 software.amazon.awssdk 版本 2.7.11 一直到 2.7.29

基本代码片段

    String amazonAccessKeyId = "amazonAccessKeyId";
    String amazonSecretKeyId = "amazonSecretKeyId";
    String baseRegionName = "baseRegionName"; // Region.AP_NORTHEAST_1.id(); or where ever your snapshot is located
    String remoteRegionName = "remoteRegionName "; // Region.AP_NORTHEAST_1.id(); or where ever your snapshot is located
    String snapshotId = "snapshotId"; // You will need a snapshot to work with this code

    // Setup AWS remote client with credentials
    AwsCredentials credentials = AwsBasicCredentials.create(amazonAccessKeyId, amazonSecretKeyId);

    Ec2Client amazonEc2RemoteRegionClient = Ec2Client.builder()
                    .region(Region.of(remoteRegionName))
                    .credentialsProvider(StaticCredentialsProvider.create(credentials))
                    .build();

    // Setup request
    CopySnapshotRequest request = CopySnapshotRequest.builder()
                    .sourceRegion(Region.of(baseRegionName).id())
                    .sourceSnapshotId(snapshotId)
                    .description("Foo Bar Testing...")
                    .build();

    // Invoke copy from remote region to pull in snapshot from source/default region
    // This is the line in question
    CopySnapshotResponse result = amazonEc2RemoteRegionClient.copySnapshot(request);

堆栈跟踪如下

我希望将快照复制到指定的新区域，没有错误，也没有加密。

作为旁注，我已通过我的支持系统将此提交给亚马逊，我正在等待他们的回复。一旦他们回复我的请求，我将更新这篇文章。

copySnapshot sdk 错误，带有 presignedUrl 的构建器可以跳过它
