    In this tutorial, suppose that:

    • You want to use SCF to implement a web backend service, such as querying the articles in a blog and providing the article contents.
    • You want to use APIs to provide services for webpages and applications.

    Implementation Overview

    The implementation process of the service is as follows:

    • Create a function, configure API rules in API Gateway, and point the backend service to the function.
    • A user sends a request that contains an article ID to the API.
    • SCF queries the content corresponding to the ID according to the request parameters and responds to the request in JSON format.
    • The user performs subsequent processing after receiving the response in JSON format.

    Note: after going through this tutorial, your account will have the following resources:

    • An SCF function triggered by API Gateway.
    • An API service in API Gateway and related API rules.

    This tutorial is divided into three parts:

    • Complete the coding, creation, and testing of a function.
    • Complete the design, creation, and configuration of an API service and API rules.
    • Test and verify the correctness of the API through a browser or HTTP request tool.

    API Design

    The design of APIs for modern applications usually follows the RESTful specification. Therefore, in this example, we design the API for getting blog articles as follows:

    • /article GET
      Return the article list

    • /article/{articleId} GET
      Return the article content based on the article ID
