Python 3.x 使用DataRicks将txt文件从Azure文件复制到Blob存储

我想从Azure文件中读取一个文件（通过使用ShareClient成功），并将此文件导出到Azure blob存储

首先，我使用以下代码在Databricks中装载容器：

def mount(container, account_name):
    """Mount a container in blob storage"""
    mount_list = [_.mountPoint for _ in dbutils.fs.mounts()]
    mount_point = f"/mnt/{container}/"
    if mount_point not in mount_list:
        dbutils.fs.mount(
                source = f"wasbs://{container}@{account_name}.blob.core.windows.net/",
                mount_point = mount_point,
                extra_configs = {f"fs.azure.account.key.saweaaedwh.blob.core.windows.net":dbutils.secrets.get(scope = "KEY-WE-AAE-DWH", key = f"key-{account_name}")})
        print(f"Container {container} is successfully mounted")
    else:
        print("Container is already mounted")

with open(f"/dbfs/mnt/datascience/spc/failed2/test.txt", "wb") as outfile:
    download_stream = file_client.download_file()
    outfile.write(download_stream.readall())

当我想上传带有以下代码的文件时：

def mount(container, account_name):
    """Mount a container in blob storage"""
    mount_list = [_.mountPoint for _ in dbutils.fs.mounts()]
    mount_point = f"/mnt/{container}/"
    if mount_point not in mount_list:
        dbutils.fs.mount(
                source = f"wasbs://{container}@{account_name}.blob.core.windows.net/",
                mount_point = mount_point,
                extra_configs = {f"fs.azure.account.key.saweaaedwh.blob.core.windows.net":dbutils.secrets.get(scope = "KEY-WE-AAE-DWH", key = f"key-{account_name}")})
        print(f"Container {container} is successfully mounted")
    else:
        print("Container is already mounted")

with open(f"/dbfs/mnt/datascience/spc/failed2/test.txt", "wb") as outfile:
    download_stream = file_client.download_file()
    outfile.write(download_stream.readall())

出现以下错误消息：

FileNotFoundError: [Errno 2] No such file or directory: '/dbfs/mnt/datascience/spc/failed2/test.txt'

为了创建此目录，我使用了以下代码：

dbutils.fs.mkdirs('/mnt/datascience/spc/failed2/test.txt')

问题是，这也会创建“空”目录。如果目录至少包含一个文件，您知道如何创建目录吗

您能详细描述一下您的问题吗？路径

/dbfs/mnt/datascience/spc/failed2

不存在，您希望在该路径中创建一个文件。对吗？我在第一个代码片段中安装了带有Databricks的Blob存储。之后，我想上传一个txt文件到blob存储。其中spc/failed2目录尚不存在。所以我使用dbutils.fs.mkdirs来创建这样一个目录。然后创建了空文件夹和普通文件夹（重复），看起来很乱。（请参见创建内容的图片）Azure Blob服务基于平面存储方案，而不是分层方案。它没有

目录

。它只是在blob名称中使用字符或字符串分隔符来创建虚拟层次结构。因此，当我们使用dbutils.fs.mkdirs创建东西时，Blob服务器只会认为我们想要创建Blob。有关更多详细信息，请参阅。
