Google Cloud SDK Python客户端:如何在Cloud Storage存储桶中列出文件? [英] Google Cloud SDK Python Client: How to list files inside of a Cloud Storage bucket?

问题描述

尝试使用Python来获取和遍历我拥有的Cloud Storage存储桶中的所有文件.我正在使用官方库 google-cloud-storage .

Trying to use Python to get and iterate through all of the files inside of a Cloud Storage bucket I own. I'm using the official library, google-cloud-storage.

使用 gsutil ，我可以运行 gsutil ls gs://my-composer-bucket/dags/composer_utils/之类的命令. google-cloud-storage 库是否提供与 gsutil ls 等效的方法?我想使用Python客户端，而不是使用 gsutil (不想在Docker映像中安装和验证GCloud SDK).

Using gsutil, I can run commands like gsutil ls gs://my-composer-bucket/dags/composer_utils/. Does the google-cloud-storage library offer an equivalent method to gsutil ls? I'd like to use the Python client rather than shell out to gsutil (don't want to install and authenticate the GCloud SDK inside of a Docker image).

我尝试了一些不同的操作，这些操作使我对blob的工作方式感到困惑:

I've tried a few different things which have left me confused on how blobs work:

>>> dag_folder_blob = cloud_composer_bucket.blob(bucket, 'dags/')
>>> dag_folder_blob.exists()
True
>>> util_folder_blob = cloud_composer_bucket.blob(bucket, 'dags/composer_utils/')  # directory exists
>>> util_folder_blob.exists()
False
>>> util_file_blob = cloud_composer-bucket.blob(bucket, 'dags/composer_utils/__init__.py')
>>> util_file_blob.exists()
True

推荐答案

您将要使用列出云存储中对象的更多信息.

You will want to use the list_blobs method of a Bucket object. Read more about listing objects in Cloud Storage.
