如何正确使用谷歌云存储 python 库中的 create_anonymous_client() 函数来访问公共存储桶?

问题描述

I made a publicly listable bucket on google cloud storage. I can see all the keys if I try to list the bucket objects in the browser. I was trying to use the create_anonymous_client() function so that I can list the bucket keys in the python script. It is giving me an exception. I looked up everywhere and still can't find the proper way to use the function.

from google.cloud import storage

client = storage.Client.create_anonymous_client()
a = client.lookup_bucket('publically_listable_bucket')
a.list_blobs()

Exception I am getting:

ValueError: Anonymous credentials cannot be refreshed.

Additional Query: Can I list and download contents of public google cloud storage buckets using boto3, If yes, how to do it anonymously?

解决方案

I was also struggling with thing and couldn't find an answer anywhere online. Turns out you can access the bucket with just the bucket() method.

I'm not sure why, but this method can take several seconds sometimes.

client = storage.Client.create_anonymous_client()

bucket = client.bucket('publically_listable_bucket')

blobs = list(bucket.list_blobs())
