How to use Boto3 to find whether a function can paginate or not in AWS Secret Manager
Problem Statement: Use boto3 library in Python to find out whether a function can paginate or not in AWS secret.
Approach/Algorithm to solve this problem
Step 1: Import boto3 and botocore exceptions to handle exceptions.
Step 2: secret_function is the required parameter in this function.
Step 3: Create an AWS session using boto3 lib. Make sure region_name is mentioned in the default profile. If it is not mentioned, then explicitly pass the region_name while creating the session.
Step 4: Create an AWS client for secretmanager.
Step 5: Now use the can_paginate function and pass the parameter secret_function.
Step 6: It returns True if the function can paginate; else False.
Step 7: Handle the generic exception if something went wrong while checking the pagination.
Example Code
Use the following code to check pagination −
import boto3 from botocore.exceptions import ClientError def check_pagination(secret_function) session = boto3.session.Session() client = session.client('secretmanager') try: response = client.can_paginate(secret_function) return response except ClientError as e: raise Exception("boto3 client error in check_pagination: " + e.__str__()) except Exception as e: raise Exception("Unexpected error in check_pagination: " + e.__str__()) print(check_pagination("list_secrets")) print(check_pagination("get_secret_value"))
Output
True False
