问题描述
介绍一段Python脚本，可以在微软云中国区使用。
用于计算Azure Storage Account中Container中Blob类型文件的数量和大小，脚本中允许按照容器，层(热/冷/归档)，前缀，软删除/非软删除来计算数量和容量大小， 默认使用的时间为以Blob的最后修改时间作为参考。
执行结果参考：
参数介绍
所有值都是强制性的，有些可以为空，参考如下的描述以及脚本中解释。
$storageAccountName - 只需运行脚本，系统就会询问存储帐户名称。
$containerName - 指定一些容器名称，或为空（默认值）以列出所有容器
$prefix - 指定一些用于扫描的 blob 前缀（不包括容器名称），或留空（默认值）以列出所有对象
$deleted - 指定“True”以仅列出软删除对象，“False”以仅列出非软删除对象（活动对象 - 默认值），或指定“All”以列出活动和软删除对象
$blobType - 选择“Base”仅列出基本 Blob（默认值），“Snapshots”仅列出快照，“Versions”仅列出版本，“Versions+Snapshots”仅列出版本和快照，或“所有类型”列出所有对象（基本 Blob、版本和快照）
$accessTier - 选择“Hot”仅列出“Hot”层中的对象，“Cool”仅列出“Cool”层中的对象，“Archive”仅列出存档层中的对象，或选择“All”以列出所有层中的对象（Hot、酷并存档）
$Year、$Month、$Day - 定义一个日期，仅列出上次修改日期之前或等于该日期的对象 - 如果至少有一个值为空，则将使用当前日期。
注意
此脚本不会支持统计 ADLS Gen2 帐户中的文件夹。
只需运行脚本就会要求提供 AAD 凭据并选择要列出的存储帐户名称。
默认情况下（不更改任何参数，脚本将列出存储帐户中所有容器上、所有访问层的所有基本 Blob，且上次修改日期早于或等于当前日期时间。
所有其他选项（上面）应在脚本中定义。
这可能需要数(小时/天)才能完成，具体取决于容器或存储帐户中的 blob、版本和快照的数量。
$logs 容器中的内容不被统计（不支持）
权限
若要使用 AAD 列出 Blob，执行脚本的Azure账号(或AAD 应用)需要拥有“Storage Blob Data Reader (存储 Blob 数据读取者)”角色。 否则，会遇见权限错误“The client 'xxx@xxxx.partner.onmschina.cn' with object id 'xx-x-x-x-xxx' does not have authorization to perform action 'Microsoft.Storage/storageAccounts/listKeys/action' over scope '/subscriptions/xxxxx' or the scope is invalid.”, 参考文档（

2 # Azure Storage Blob calculator:
3 # Base Blobs, Blob Snapshots, Versions, Deleted / not Deleted, by Container, by tier, with prefix and considering Last Modified Date
4 # ====================================================================================
5 # This PowerShell script will count and calculate blob usage on each container, or in some specific container in the provided Storage account
6 # Filters can be used based on
7 # All containers or some specific Container
8 # Base Blobs, Blob Snapshots, Versions, All
9 # Hot, Cool, Archive or All Access Tiers
10 # Deleted, Not Deleted or All
11 # Filtered by prefix
12 # Filtered by Last Modified Date
13 # This can take some hours to complete, depending of the amount of blobs, versions and snapshots in the container or Storage account.
14 # $logs container is not covered by this script (not supported)
15 # By default, this script List All non Soft Deleted Base Blobs, in All Containers, with All Access Tiers
16 # ====================================================================================
17 # DISCLAMER : Please note that this script is to be considered as a sample and is provided as is with no warranties express or implied, even more considering this is about deleting data.
18 # You can use or change this script at you own risk.
19 # ====================================================================================
20 # PLEASE NOTE :
21 # - This script does not recover folders on ADLS Gen2 accounts.
22 # - Just run the script and your AAD credentials and the storage account name to list will be asked.
23 # - All other values should be defined in the script, under 'Parameters - user defined' section.
24 # - Uncomment line 180 (line after # DEBUG) to get the full list of all selected objects
25 # ====================================================================================
26 #
27 # ====================================================================================

29 # - Null array exception for empty containers
