Google Cloud Storage - 将文件从一个文件夹移动到另一个文件夹 - 使用 Python

问题描述

我想将文件列表从谷歌存储移动到另一个文件夹:

I would like to move a list of file from google storage to another folder:

storage_client = storage.Client()
count = 0

# Retrieve all blobs with a prefix matching the file.
bucket=storage_client.get_bucket(BUCKET_NAME)
# List blobs iterate in folder 
blobs=bucket.list_blobs(prefix=GS_FILES_PATH, delimiter='/') # Excluding folder inside bucket
for blob in blobs:
if fnmatch.fnmatch(blob.name, FILE_PREF):
         WHAT CAN GO HERE?
         count += 1   

我在 Google 文档中找到的唯一有用信息是:

The only useful information which I found in Google Documentation is:

• https://cloud.google.com/storage/docs/重命名复制移动对象

根据本文档，唯一的方法是从一个文件夹复制到另一个文件夹并删除它.

By this documentation, the only method is to copy from one folder to another and delete it.

1. 有什么方法可以实际移动文件?
2. 根据前缀移动所有文件的最佳方法是什么，例如 *BLABLA*.csv

附:不想用

• "gsutil mv gs://[SOURCE_BUCKET_NAME]/[SOURCE_OBJECT_NAME]gs://[DESTINATION_BUCKET_NAME]/[DESTINATION_OBJECT_NAME]"

推荐答案

这可能是一个可能的解决方案，因为 google.cloud.storage 中没有 move_blob 函数:

This could be a possible solution, as there is no move_blob function in google.cloud.storage:

from google.cloud import storage  

dest_bucket = storage_client.create_bucket(bucket_to)
source_bucket = storage_client.get_bucket(bucket_from)
blobs = source_bucket.list_blobs(prefix=GS_FILES_PATH, delimiter='/') #assuming this is tested

for blob in blobs:
    if fnmatch.fnmatch(blob.name, FILE_PREF): #assuming this is tested
        source_bucket.copy_blob(blob,dest_bucket,new_name = blob.name)
        source_bucket.delete_blob(blob.name)
