php – Creating RESTful API by using pure CodeIgniter?

Posted by: admin July 12, 2020 Leave a comment

Questions:

I need to create a RESTful web api using only CodeIgniter. I can not use any third-party plugins or libraries to do this. I have seen that most people are using https://github.com/chriskacerguis/codeigniter-restserver. Please guide me on writing a REST api only using CodeIgniter. Helpful links and steps are highly appreciated.

Thanks in Advance.

How to&Answers:

If your are using version 3, you can do this

create a controller users.php

class Users extends CI_Controller {

    /**
    * @route http://proyect/users
    * @verb GET
    */
    public function get()
    {
        echo "Get";
    }

    /**
    * @route http://proyect/users
    * @verb POST
    */
    public function store()
    {
        echo "Add";
    }

    /**
    * @route http://proyect/users
    * @verb PUT
    */
    public function update()
    {
        echo "Update";
    }

    /**
    * @route http://proyect/users
    * @verb DELETE
    */
    public function delete()
    {
        echo "Delete";
    }

}

edit (add) in your application/config/route.php

$route["users"]["get"]    = "users/get";
$route["users"]["post"]   = "users/store";
$route["users"]["update"] = "users/update";
$route["users"]["delete"] = "users/delete";

$route['products/([a-zA-Z]+)/edit/(\d+)'] = function ($product_type, $id)
{
        return 'catalog/product_edit/' . strtolower($product_type) . '/' . $id;
};
