我想调用在Cloudformation中维护的API网关 . 我有Cloudformation堆栈名称( CF_STACK_NAME
),API网关资源名称( API_GATEWAY_NAME
)和我需要假设的IAM角色的Cloudformation名称( API_ROLE_NAME
) .
我可以通过以下方式访问我的Cloudformation堆栈
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Switching to an IAM Role,我看到如何获取我的角色,
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网址时,
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()
我明白了
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
如何使用此CloudFormation信息进行API调用?

我的猜测是你没有使用STS的新证书 .
您需要使用以下代码使用新凭据创建apigateway客户端:
