如何在Azure存储容器中创建目录，而不创建额外的文件？

问题描述

我已经创建了在Azure存储容器中创建一系列文件夹和子文件夹(用于数据湖)的Python代码。该代码工作正常，并基于Microsoft Azure上的文档。不过，有一件事是我在文件夹中创建了一个虚拟的‘txt’文件，以便创建目录(我可以稍后清理它)。我想知道是否有一种方法可以在不创建文件的情况下创建文件夹和子文件夹。我知道Azure容器存储中的文件夹不是分层的，而是元数据，我所要求的可能是不可能的？

connection_string = config['azure_storage_connectionstring']
gen2_container_name = config['gen2_container_name']
container_client = ContainerClient.from_connection_string(connection_string, gen2_container_name)
blob_service_client = BlobServiceClient.from_connection_string(connection_string)

# blob_service_client.create_container(gen2_container_name)


def create_folder(folder, sub_folder):
    blob_client = container_client.get_blob_client('{}/{}/start_here.txt'.format(folder, sub_folder)) 

    with open ('test.txt', 'rb') as data:
        blob_client.upload_blob(data)



def create_all_folders():
    config = load_config()
    folder_list = config['folder_list']
    sub_folder_list = config['sub_folder_list']
    for folder in folder_list:
        for sub_folder in sub_folder_list:
            try:
                create_folder(folder, sub_folder)
            except Exception as e:
                print ('Looks like something went wrong here trying to create this folder structure {}/{}. Maybe the structure already exists?'.format(folder, sub_folder))

推荐答案

但您可以像这样使用data-lake SDK创建目录：

from azure.storage.filedatalake import DataLakeServiceClient 
connect_str = "DefaultEndpointsProtocol=https;AccountName=0730bowmanwindow;AccountKey=xxxxxx;EndpointSuffix=core.windows.net"
datalake_service_client = DataLakeServiceClient.from_connection_string(connect_str)
myfilesystem = "test"
myfolder     = "test1111111111"
myfile       = "FileName.txt"

file_system_client = datalake_service_client.get_file_system_client(myfilesystem)            
directory_client = file_system_client.create_directory(myfolder)
