Azure文件共享服务提供了多种方式的访问接口,包括Powershell,.Net, Java, Python等等,本章主要介绍如何使用Python来访问Azure File存储。
from azure.storage.file import FileService
from azure.storage.file import ContentSettings
endpointSuffix = "core.chinacloudapi.cn"
myStorageAccount = "mystorageacctfile"
myStorageKey = "Your account key"
mysharename = "mypythonshare"
mydirname = "sampledir"
#initial file service
file_service = FileService(account_name=myStorageAccount, account_key=myStorageKey,endpoint_suffix=endpointSuffix)
#create file share
if(not file_service.exists(mysharename)):
file_service.create_share(mysharename)
#create directory under the share
if(not file_service.exists(mysharename,mydirname)):
file_service.create_directory(mysharename, mydirname)
# upload a file to the share at directory you just created
file_service.create_file_from_path(
mysharename,
mydirname,
‘hdinsight.publishsettings‘,
‘d:\\hdinsight.publishsettings‘)
7. 你可以通过Python的API列举出共享下,根目录下所有的文件,或者指定目录,列出指定目录下所有的文件或者目录:
#List files and directories of the share
filediritertors = file_service.list_directories_and_files(mysharename,mydirname)
for file_or_dir in filediritertors:
print(file_or_dir.name)
8. 那么怎么从文件中获取内容或者获取整个文件? Python SDK也提供了多种方式,比如get_file_to_path, get_file_to_stream, get_file_to_bytes, or get_file_to_text. 等,本例中奖文件保存到本地:
#Download file to local path
file_service.get_file_to_path(mysharename, mydirname, ‘hdinsight.publishsettings‘, ‘D:\\movie\\hdinsight.publishsettings‘)
9. 最后,看看如何删除文件,删除目录,删除共享,也比较简单:
#delete a file
file_service.delete_file(mysharename, mydirname, ‘hdinsight.publishsettings‘)
#delete a directory
file_service.delete_directory(mysharename,mydirname)
#delete a share
if(file_service.exists(share_name=mysharename)):
file_service.delete_share(mysharename)
利用Python来访问文件共享还是非常方便的,File share的方式也利用多种不同的平台,不同的语言,提供数据交换和共享,可以在合适的场景中使用。
