如何使用Python客户端API下载含特殊字符的GCS云存储桶文件？

我使用Windows系统，能够正常下载文件名不含特殊字符的GCS文件，但无法下载含竖线|的文件，例如文件名：BRX_23022023|00000.csv。

我编写的代码可根据bucketname和foldername变量创建对应文件夹结构，但遇到含特殊字符的文件时，仅创建文件夹却无法下载文件，本地路径示例：C:\adt-dev-outputs\archive\2023\02。

代码示例 #

import os
from google.cloud import storage
from os import makedirs

cred_json_file_path = 'C:/Users/config.json'
client = storage.Client.from_service_account_json(cred_json_file_path)

def download_blob(bucket: storage.Bucket, remotefile: str, localpath: str='.'):
    """downloads from remotepath to localpath"""
    localrelativepath = '/'.join(remotefile.split('/')[:-1])
    totalpath = f'{localpath}/{localrelativepath}'
    filename = f'{localpath}/{remotefile}'
    makedirs(totalpath, exist_ok=True)
    print(f'Current file details:\n  remote file: {remotefile}\n  local file:  {filename}\n')
    blob = storage.Blob(remotefile, bucket)
    blob.download_to_filename(filename, client=client)


def download_blob_list(bucketname: str, bloblist: list, localpath: str='.'):
    """downloads a list of blobs to localpath"""
    bucket = storage.Bucket(client, name=bucketname)
    for blob in bloblist:
        download_blob(bucket, blob, localpath)


def list_blobs(bucketname: str, remotepath: str=None, filetypes: list=[]) -> list:
    """returns a list of blobs filtered by remotepath and filetypes
    remotepath and filetypes are optional"""
    result = []
    blobs = list(client.list_blobs(bucketname, prefix=remotepath))
    for blob in blobs:
        name = str(blob.name)
        # skip "folder" names
        if not name.endswith('/'):
            # do we need to filter file types?
            if len(filetypes) > 0:
                for filetype in filetypes:
                    if name.endswith(filetype):
                        result.append(name)
            else:
                result.append(name)
    return result


bucketname = 'adt-dev-outputs'
foldername = 'archive/2023/02'
filetypes = ['.csv'] # list of extentions to return
bloblist = list_blobs(bucketname, remotepath=foldername, filetypes=filetypes)

download_blob_list(bucketname, bloblist, localpath=bucketname)
