使用 Python 列出具有特定名称类型的 azure 容器

Question

我正在尝试列出一堆具有特定名称类型的 azure 容器 - 它们都称为cycling-asset-group-x，其中 x 是数字或字母，例如循环资产组a，循环资产组1，循环资产组b，循环资产组2。

我只想打印带有 number 后缀的容器，即cycling-asset-group-1、cycling-asset-group-2等

我该怎么做？到目前为止，这是我的目标：

account_name   = 'name'
account_key    = 'key'

# connect to the storage account 
blob_service   = BaseBlobService(account_name = account_name, account_key = account_key)
prefix_input_container = 'cycling-asset-group-'

# get a list of the containers - I think it's something like this...? 
cycling_containers = blob_service.list_containers("%s%d" % (prefix_input_container,...)) 

for c in cycling_containers:
    contname = c.name
    print(contname)

Answer 1

只需将您的prefix_input_container 值传递给BaseBlobService 的方法list_containers 的参数prefix，如下代码所示。请参阅 API 参考 BaseBlobService.list_containers。

list_containers(prefix=None, num_results=None, include_metadata=False, marker=None, timeout=None)[来源]

参数：
prefix (str) – 过滤结果以仅返回名称以指定前缀开头的容器。

prefix_input_container = 'cycling-asset-group-'

cycling_containers = blob_service.list_containers(prefix=prefix_input_container) 

# Import regex module to filter the results
import re
re_expression = r"%s\d+$" % prefix_input_container
pattern = re.compile(re_expression)

# There are two ways.
# No.1 Create a generator from the generator of cycling_containers 
filtered_cycling_container_names = (c.name for c in cycling_containers if pattern.match(c.name))
for contname in filtered_cycling_container_names:
    print(contname)

# No.2 Create a name list
contnames = [c.name for c in cycling_containers if pattern.match(c.name)]
print(contnames)
