使用云存储选项从 google 存储桶中的目录中删除所有对象
Delete all objects from a directory in google storage bucket using cloud storage options
我正在使用来自 google 云的云存储选项来管理 GCP 存储桶中的数据。我有一个目录,我想在开始编写新对象之前删除该目录下的所有对象。
示例目录:gs://bucket-name/directory1/subdirectory/
我可以使用以下代码删除单个对象,但如何获取目录中所有对象的列表并删除所有对象?
import com.google.cloud.storage.Storage;
import com.google.cloud.storage.StorageOptions;
public class DeleteObject {
public static void deleteObject(String projectId, String bucketName, String objectName) {
// The ID of your GCP project
// String projectId = "your-project-id";
// The ID of your GCS bucket
// String bucketName = "your-unique-bucket-name";
// The ID of your GCS object
// String objectName = "your-object-name";
Storage storage =
StorageOptions.newBuilder().setProjectId(projectId).build().getService();
storage.delete(bucketName, objectName);
System.out.println("Object " + objectName + " was deleted from " + bucketName);
}
}
在 bucket
中使用目录名称的前缀迭代 objects
。
请参阅以下代码段:
Storage storage = StorageOptions.newBuilder().setProjectId(projectId).build().getService();
Page<Blob> blobs =
storage.list(
bucketName,
Storage.BlobListOption.prefix(directoryPrefix), // directoryPrefix is the sub directory.
Storage.BlobListOption.currentDirectory());
for (Blob blob : blobs.iterateAll()) {
blob.delete(Blob.BlobSourceOption.generationMatch());
}
