Google云端存储-将文件从一个文件夹移动到另一个文件夹-使用Python [英] Google Cloud Storage - Move file from one folder to another - By using Python

问题描述

我想将文件列表从Google存储设备移到另一个文件夹:

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的信息是:

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

• https://cloud.google.com/storage/docs/renaming-copying-moving-objects

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将其删除.

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

1. 有什么方法可以真正移动文件?
2. 移动基于PREFIX的所有文件的最佳方法是什么，例如 * BLABLA * .csv

P.S.不想使用

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

推荐答案

这可能是一种可能的解决方案，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)
