A Complete REST API Tutorial

Hello, is there a fully completed example project or tutorial?

I'm trying to build REST API test in CI4. 

I've tried the steps described here : https://codeigniter4.github.io/userguide...stful.html 

But unfortunately when I try to reach controller, it's returning as an empty XML file. What do I missing? 

I was expecting a JSON file that contains data. 

I've never worked with APIs before. So I would be happy if you could explain it simply. 

I've used to following code: (I'm connected to database and I can see the raw data with "print_r")


Controller

PHP Code:

<?php 

namespace App\Controllers;

use CodeIgniter\RESTful\ResourceController;

class Categories extends ResourceController {

    public function __construct() {
        $this->modelName = 'App\Models\Categories';
    }

    public function index()    {
        $this->respond($this->model->findAll(),200);
    }
    
} 


Model

PHP Code:

<?php

namespace App\Models;

use CodeIgniter\Model;

class Categories extends Model {
    protected $table = 'categories';
} 


Routes

PHP Code:

$routes->resource('categories'); 


No full tutorial yet, sorry.
It's on my to-do list, though ... https://github.com/codeigniter4/CodeIgni...ssues/2186

You need set JSON response in your request. From the browser it will always be XML.
You can JSON only leave in app/Config/Format.php, comment line 23 and 39:

PHP Code:

'application/xml', // machine-readable XML
'application/xml'  => \CodeIgniter\Format\XMLFormatter::class

Hello, you can use the cli-create plugin.

Using this plugin you will be able to create rest-ful api controller and any files in the command line.

After my testing, in the Codeigniter  current version v4.0.2 will be able to automatically create a functioning APIs.
