本文整理了Java中com.google.cloud.storage.Bucket.list()方法的一些代码示例,展示了Bucket.list()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台,是从一些精选项目中提取出来的代码,具有较强的参考意义,能在一定程度帮忙到你。Bucket.list()方法的具体详情如下:
包路径:com.google.cloud.storage.Bucket
类名称:Bucket
方法名:list

Bucket.list介绍

[英]Returns the paginated list of Blob in this bucket.

Example of listing the blobs in the bucket.

Page blobs = bucket.list();}

[中]返回此存储桶中已分页的Blob列表。
在bucket中列出blob的示例。

Page blobs = bucket.list();}

代码示例

/** Example of listing the blobs in the bucket. */
// [TARGET list(BlobListOption...)]
public Page<Blob> listBlobs() {
 // [START listBlobs]
 Page<Blob> blobs = bucket.list();
 for (Blob blob : blobs.iterateAll()) {
  // do something with the blob
 }
 // [END listBlobs]
 return blobs;
}

  // List all your buckets
