Azure File File Share (6): Developing with Python

The Azure File Sharing service provides a variety of ways to access interfaces, including Powershell,.net, Java, Python, and so on, and this chapter focuses on using Python to access Azure file storage.

2. For the installation of the Python environment, the installation configuration for the Azure SDK for Python, the module upgrade on Linux and Windows, please refer to the blog:

4. First, import the modules required for the Azure storage file:

   from azure.storage.file import fileservice
   from azure.storage.file import contentsettings

6. The default service endpoint is to global Azure, so you first need to set up a service URL for China Azure, and you need to set up your storage account, stored key and other basic information

    

     Span style= "color:black; font-size:9pt; " >endpointsuffix =   "core.chinacloudapi.cn" 
     mystorageaccount =   "Mystorageacctfile" 
     mystoragekey =   "Your account Key" 
     mysharename =   "Mypythonshare" 
     mydirname =   "Sampledir"             

    

8. Initialize your file service:

   #initial file service
   file_service = FileService(account_name=myStorageAccount, account_key=myStorageKey,endpoint_suffix=endpointSuffix)

5. Create your file share and directory:

#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)

6. After the catalog is created, you can upload files, write files, upload or write files in several ways, such as Create_ File_from_bytes  or  create_file_from_text   , Create_file_from_path create_file_from_stream , create_file_from_bytes et cetera, use as needed , this test uses the create_file_from_path :

    # 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。
