GCP-获取有关存储桶的完整信息 [英] GCP - get full information about bucket

问题描述

我需要获取存储在Google Bucket中的文件信息. 文件大小，存储类别，上次修改的类型之类的信息.我搜索了google文档，但是可以通过curl或console方法来完成.我需要从Python API获得该信息，例如下载blob，将blob上传到存储桶.示例代码或任何帮助表示赞赏！

I need to get the file information stored in Google Bucket. Information Like Filesize, Storage Class, Last Modified, Type. I searched for the google docs but it can be done by curl or console method. I need to get that information from the Python API like downloading the blob, uploading the blob to the bucket. Sample code or any help is appreciated!!

推荐答案

到获取对象元数据，您可以使用以下代码:

To get the object metadata you can use the following code:

from google.cloud import storage

def object_metadata(bucket_name, blob_name):
    """Prints out a blob's metadata."""
    storage_client = storage.Client()
    bucket = storage_client.get_bucket(bucket_name)
    blob = bucket.get_blob(blob_name)

    print('Blob: {}'.format(blob.name))
    print('Bucket: {}'.format(blob.bucket.name))
    print('Storage class: {}'.format(blob.storage_class))
    print('ID: {}'.format(blob.id))
    print('Size: {} bytes'.format(blob.size))
    print('Updated: {}'.format(blob.updated))
    print('Generation: {}'.format(blob.generation))
    print('Metageneration: {}'.format(blob.metageneration))
    print('Etag: {}'.format(blob.etag))
    print('Owner: {}'.format(blob.owner))
    print('Component count: {}'.format(blob.component_count))
    print('Crc32c: {}'.format(blob.crc32c))
    print('md5_hash: {}'.format(blob.md5_hash))
    print('Cache-control: {}'.format(blob.cache_control))
    print('Content-type: {}'.format(blob.content_type))
    print('Content-disposition: {}'.format(blob.content_disposition))
    print('Content-encoding: {}'.format(blob.content_encoding))
    print('Content-language: {}'.format(blob.content_language))
    print('Metadata: {}'.format(blob.metadata))

object_metadata('bucketName', 'objectName')
