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
1List<BucketSummary> buckets = client.listBuckets().getBuckets();
2// 遍历Bucket
3for (BucketSummary bucket : buckets) {
4 System.out.println(bucket.getName());
5 }如下代码可以列出Bucket的Owner：
Java
1User usr = client.listBuckets().getOwner();
2System.out.println(usr.getDisplayName());
3System.out.println(usr.getId());如下代码可以列出Bucket的Metadata：
Java
1BosResponseMetadata metaData = client.listBuckets().getMetadata();
2System.out.println(metaData.getBceRequestId());
3System.out.println(metaData.getBceContentSha256());
4System.out.println(metaData.getContentLength());
5System.out.println(metaData.getEtag());
6System.out.println(metaData.getExpires());
7System.out.println(metaData.getContentMd5());
8System.out.println(metaData.getContentDisposition());
9System.out.println(metaData.getLastModified());注意：Bucket如果没有设置这些参数，返回时可能为空。
