您可以将文件从一个存储空间（源存储空间）拷贝到同一地域的另一个存储空间（目标存储空间）中。

以下代码用于拷贝文件。

// 创建copy请求
CopyObjectRequest copyObjectRequest = new CopyObjectRequest("<srcBucketName>", "<srcObjectKey>",
        "<destBucketName>", "<destObjectKey>");

// 可选设置copy文件元信息
// ObjectMetadata objectMetadata = new ObjectMetadata();
// objectMetadata.setContentType("application/octet-stream");
// copyObjectRequest.setNewObjectMetadata(objectMetadata);

// 异步copy
OSSAsyncTask copyTask = oss.asyncCopyObject(copyObjectRequest, new OSSCompletedCallback<CopyObjectRequest, CopyObjectResult>() {
    @Override
    public void onSuccess(CopyObjectRequest request, CopyObjectResult result) {
            Log.d("copyObject", "copy success!");
    }

    @Override
    public void onFailure(CopyObjectRequest request, ClientException clientExcepion, ServiceException serviceException) {
        // 请求异常
        if (clientExcepion != null) {
            // 本地异常如网络异常等
            clientExcepion.printStackTrace();
        }
        if (serviceException != null) {
            // 服务异常
            Log.e("ErrorCode", serviceException.getErrorCode());
            Log.e("RequestId", serviceException.getRequestId());
            Log.e("HostId", serviceException.getHostId());
            Log.e("RawMessage", serviceException.getRawMessage());
        }
    }
});
