Resources and methods in AWS - Mini Project: Build & Apply

AWS API Gateway: Resources and Methods Setup

📖 Scenario: You are building a simple API using AWS API Gateway. This API will have a resource path and a method to handle HTTP requests.Think of this like setting up a new phone line (resource) and deciding what kind of calls (methods) it can take.

🎯 Goal: Create an AWS API Gateway REST API with a resource path /products and add a GET method to it.

📋 What You'll Learn

Create a REST API named StoreAPI

Add a resource with path part products

Add a GET method to the /products resource

💡 Why This Matters

🌍 Real World

APIs are the backbone of modern applications. Setting up resources and methods in API Gateway allows you to create scalable and secure APIs for your services.

💼 Career

Cloud engineers and developers often need to configure API Gateway resources and methods to expose backend services securely and efficiently.

1

Create the REST API

Create a REST API named StoreAPI using AWS SDK or AWS CLI syntax. Assign it to a variable called api.

AWS

# Your code here to create a REST API named StoreAPI and assign it to api

Need a hint?

Use create_rest_api method with name='StoreAPI'.

2

Add the /products resource

Add a resource with path part products to the REST API stored in api. Assign the new resource to a variable called products_resource.

AWS

api = apigateway.create_rest_api(name='StoreAPI')
# Your code here to add a resource with path part 'products' and assign it to products_resource

Need a hint?

Use create_resource with restApiId=api['id'], parentId=api['rootResourceId'], and pathPart='products'.

3

Add GET method to /products

Add a GET method to the products_resource. Use authorizationType='NONE' and assign the method response to a variable called get_method.

AWS

api = apigateway.create_rest_api(name='StoreAPI')
products_resource = apigateway.create_resource(restApiId=api['id'], parentId=api['rootResourceId'], pathPart='products')
# Your code here to add a GET method with authorizationType 'NONE' and assign it to get_method

Need a hint?

Use put_method with restApiId=api['id'], resourceId=products_resource['id'], httpMethod='GET', and authorizationType='NONE'.

4

Add integration for GET method

Add a MOCK integration to the GET method on products_resource. Use type='MOCK' and assign the integration response to a variable called get_integration.

AWS

api = apigateway.create_rest_api(name='StoreAPI')
products_resource = apigateway.create_resource(restApiId=api['id'], parentId=api['rootResourceId'], pathPart='products')
get_method = apigateway.put_method(restApiId=api['id'], resourceId=products_resource['id'], httpMethod='GET', authorizationType='NONE')
# Your code here to add a MOCK integration to the GET method and assign it to get_integration

Need a hint?

Use put_integration with restApiId=api['id'], resourceId=products_resource['id'], httpMethod='GET', type='MOCK', and integrationHttpMethod='GET'.
