Java如何下载OSS目录下得所有文件

public class AliyunHandle { public static string accessKeyId = "a1uI5xxxxxxxxxrP4H"; public static string accessKeySecret = "9JDdggMdT2cxxxxxxxxxxxxxxx5VaE9z"; public static string endpoint = "oss-cn-qingdao.aliyuncs.com"; public static string bucket = "testoss"; OssClient client = new OssClient(endpoint, accessKeyId, accessKeySecret);

        var flag = true;
        string maker = string.Empty;

        var dayTime =  *  *  * ;

        do
        {
            var listObjectsRequest = new ListObjectsRequest(bucket);

            listObjectsRequest.Marker = maker; //获取下一页的起始点，它的下一项
            listObjectsRequest.MaxKeys = ;//设置分页的页容量
            listObjectsRequest.Delimiter = "/";//跳出递归循环，只去指定目录下的文件。使用它时 Prefix文件路径要以“/”结尾
            var result = client.ListObjects(listObjectsRequest);

            Console.WriteLine("List objects succeeded");

            foreach (var summary in result.ObjectSummaries)
            {

                TimeSpan timepsan = DateTime.Now - summary.LastModified;//最后修改时间
                //时间超过一天就删除
                if (timepsan.TotalMilliseconds > dayTime)
                {
                    //删除oss文件
