查看Bucket列表

更新时间：2022-10-21

基本流程

创建BOSClient类的实例。
执行BOSClient.listBuckets()方法，会返回ListBucketsResponse类的实例。
对ListBucketsResponse类型实例可以进行getBuckets()/getOwner()/getMetadata()操作。

示例代码

如下代码可以列出用户所有的Bucket：

                Java
                
            

                List<BucketSummary> buckets = client.listBuckets().getBuckets();
// 遍历Bucket
for (BucketSummary bucket : buckets) {
   System.out.println(bucket.getName());
  }
            

如下代码可以列出Bucket的Owner：

                Java
                
                User usr = client.listBuckets().getOwner();
System.out.println(usr.getDisplayName());
System.out.println(usr.getId());

如下代码可以列出Bucket的Metadata：

                Java
                
            

                BosResponseMetadata metaData = client.listBuckets().getMetadata();
System.out.println(metaData.getBceRequestId());
System.out.println(metaData.getBceContentSha256());
System.out.println(metaData.getContentLength());
System.out.println(metaData.getEtag());
System.out.println(metaData.getExpires());
System.out.println(metaData.getContentMd5());
System.out.println(metaData.getContentDisposition());
System.out.println(metaData.getLastModified());
            

注意：Bucket如果没有设置这些参数，返回时可能为空。
