Google云存储python客户端的批处理请求

TL;DR-只需在中发送所有请求(可在
谷歌云python
库中获得)
试试这个例子:
from google.cloud import storage
storage_client = storage.Client()
bucket = storage_client.get_bucket('my_bucket_name')
# Accumulate the iterated results in a list prior to issuing
# batch within the context manager
blobs_to_delete = [blob for blob in bucket.list_blobs(prefix="my/prefix/here")]
# Use the batch context manager to delete all the blobs
with storage_client.batch():
for blob in blobs_to_delete:
blob.delete()
如果您直接使用RESTAPI,则只需担心每批100项。自动处理此限制,并在需要时发出多个批处理请求。文档中的何处提到它是上下文管理器?@NKijak文档中没有提到这一事实,但如果您查看,您可以看到enter和exit方法。顺便说一句,根据我的用法,如果超过最大批大小(当前为1000),上下文管理器将抛出异常,因此您确实需要跟踪每个批的项目数。
