我想打一个API网关保持在Cloudformation通话。 我有Cloudformation堆栈名称( CF_STACK_NAME
),API网关资源名称( API_GATEWAY_NAME
)和IAM角色,我需要承担(的Cloudformation名API_ROLE_NAME
)。
我可以通过得到我Cloudformation栈,
cf_client = boto3.client('cloudformation')
api_role_resource = cf_client.describe_stack_resource(
StackName=CF_STACK_NAME,
LogicalResourceId=API_ROLE_NAME
)
api_resource = cf_client.describe_stack_resource(
StackName=CF_STACK_NAME,
LogicalResourceId=API_GATEWAY_NAME
)
从阅读切换到IAM角色 ,我看看如何得到我的钥匙的作用,
sts_client = boto3.client('sts')
credentials = sts_client.assume_role(
RoleArn='arn:aws:iam::{account_id}:role/{role_name}'.format(
account_id=sts_client.get_caller_identity().get('Account'),
role_name=api_role_resource['PhysicalResourceId']
),
RoleSessionName="AssumeRoleSession1"
)['Credentials']
但是,当我想调用API网址,
apigateway_client = boto3.client('apigateway')
restapi_id = apigateway_client.get_rest_api(restApiId=api_logical_id)['id']
url = f'https://{restapi_id}.execute-api.{region}.amazonaws.com/{stage}/{api_query}
api_output = requests.get(url).json()
我得到的,
An error occurred (AccessDeniedException) when calling the GetRestApi operation: User: arn:aws:iam::0123456789:user/my-user is not authorized to perform: apigateway:GET on resource: arn:aws:apigateway:us-west-2::/restapis/ServerlessRestApi
我如何使用这个CloudFormation信息让我的API调用?
