CloudFormation 堆栈资源

Question

I am trying to receive Stack resources ARN information using boto3. I tried to use:

import boto3

client = boto3.resource('cloudformation', 
  aws_access_key_id='xxxxxxxx',
  aws_secret_access_key='xxxxxxxxxxxx')

response = client.list_stack_resources(
  StackName='ORG-ROLES')

I get "AttributeError: 'cloudformation.ServiceResource' object has no attribute 'list_stack_resources'" This Stack runs 9 resources, I want to get one resource ARN information. Hope you can help me.

You're mixing up the client-level and resource-level APIs. You need to use one or the other. Here's an example of each.

import boto3

session = boto3.Session(profile_name='xxxx', region_name='us-east-1')

STACK_NAME = 'ORG-ROLES'

# Use client-level API
client = session.client('cloudformation')
response = client.list_stack_resources(StackName=STACK_NAME)
print('Client API:', response['StackResourceSummaries'])

# Use resource-level API
resource = session.resource('cloudformation')
stack = resource.Stack(STACK_NAME)
print('Resource API:', list(stack.resource_summaries.all()))
