Here is a step-by-step guide to creating a simple REST API in CodeIgniter:
application/config/config.php
file. You can do this by settingand
Create a Controller: Next, create a controller in the application/controllers
directory. This controller will handle the incoming API requests and return the appropriate response.
Define the RESTful API Routes: In the controller, you need to define the routes for your RESTful API. You can do this using the $route
array in the application/config/routes.php
file. For example, if you want to create a route for the /users
endpoint, you can add the following code:
Create the API Methods: In the controller, you need to create the methods for each of the API endpoints. For example, for the /users
endpoint, you can create the following methods:
Create the API Methods: In the controller, you need to create the methods for each of the API endpoints. For example, for the /users
endpoint, you can create the following methods:
Test the API: Finally, test your API by making requests to the endpoint using a REST client, such as Postman or Insomnia. You can test the different HTTP methods (GET, POST, PUT, DELETE) to ensure that the API is working as expected.
This is a simple example to get started with a RESTful API in CodeIgniter. You can expand this example to include more endpoints, authentication, and validation as needed.
