SSM — Boto 3 文档 1.9.64 文档
get_parameters没有列出所有参数？
对于那些只想复制粘贴代码的人：
import boto3
ssm = boto3.client('ssm')
parameters = ssm.describe_parameters()['Parameters']
请注意最多 50 个参数的限制！
此代码将通过递归获取直到没有更多参数(每次调用返回 50 个最大值)来获取所有参数：
import boto3
def get_resources_from(ssm_details):
results = ssm_details['Parameters']
resources = [result for result in results]
next_token = ssm_details.get('NextToken', None)
return resources, next_token
def main()
config = boto3.client('ssm', region_name='us-east-1')
next_token = ' '
resources = []
while next_token is not None:
ssm_details = config.describe_parameters(MaxResults=50, NextToken=next_token)
current_batch, next_token = get_resources_from(ssm_details)
resources += current_batch
print(resources)
print('done')
您可以使用get_paginator api。 找到下面的示例， 在我的用例中，我必须获取 SSM 参数存储的所有值，并希望将其与字符串进行比较。
import boto3
import sys
LBURL = sys.argv[1].strip()
client = boto3.client('ssm')
p = client.get_paginator('describe_parameters')
paginator = p.paginate().build_full_result()
for page in paginator['Parameters']:
response = client.get_parameter(Name=page['Name'])
value = response['Parameter']['Value']
if LBURL in value:
print("Name is: " + page['Name'] + " and Value is: " + value)
来自上方/下方(？)的响应之一(由Val Lapidas)启发我将其扩展到此(因为他的解决方案没有获得SSM参数值以及其他一些其他详细信息)。
这里的缺点是 AWS 函数client.get_parameters()每次调用只允许 10 个名称。
我省略了此代码(to_pdatetime(...))中引用了一个引用的函数调用 - 它只是获取datetime值并确保它是一个"天真"的日期时间。这是因为我最终使用pandas将这些数据转储到 Excel 文件中，这不能很好地处理时区。

没有 ListParameters 只有 DescribeParameter，它列出了所有参数，或者您可以设置过滤器。

您可以使用get_parameters()和get_parameters_by_path()。
使用paginators.
paginator = client.get_paginator('describe_parameters')
