public void doesBucketExist (FosClient client, String bucketName) {
    // 获取Bucket的存在信息
    // 指定Bucket名称
    boolean exists = client.doesBucketExist(bucketName);

    // 输出结果
    if (exists) {
        System.out.println("Bucket exists");
    } else {
        System.out.println("Bucket not exists");
