Consume a REST API in codeigniter controller - rest

Question

I have create a REST API and want to consume my own created API in codeigniter controller.
My created REST API
controller(example.php)
class Example extends REST_Controller {
public function __construct() {
parent::__construct();
$this->load->model('user');
}
public function user_fetch_post() {
//returns all rows if the id parameter doesn't exist,
//otherwise single row will be returned
$id = $this->input->post('id');
$users = $this->user->getRows($id);
//check if the user data exists
if(!empty($users)){
//set the response and exit
$this->response($users, REST_Controller::HTTP_OK);
}else{
//set the response and exit
$this->response([
'status' => FALSE,
'message' => 'No user were found.'
], REST_Controller::HTTP_NOT_FOUND);
}
}
model(user.php)
function getRows($id = ""){
if(!empty($id)){
$query = $this->db->get_where('users', array('id' => $id));
return $query->row_array();
}else{
$query = $this->db->get('users');
return $query->result_array();
}
}
Here i want to call my created api(from example.php)for fetch record in welcome.php controller with basic authentication(uname-admin,pwd-1234)
my controller welcome.php
public function index()
{
}
Can anybody help to me that how to call my api in controller welcome.php with basic authentication.

Answer 1

Using CURL you can consume any API/network call.
<?php
$headers = array(
'Content-Type:application/json',
'Authorization: Basic '. base64_encode("user:password") // place your auth details here
);
$payload = array(
'id' => 1,
);
$process = curl_init($host); //your API url
curl_setopt($process, CURLOPT_HTTPHEADER, $headers);
curl_setopt($process, CURLOPT_HEADER, 1);
curl_setopt($process, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($process, CURLOPT_TIMEOUT, 30);
curl_setopt($process, CURLOPT_POST, 1);
curl_setopt($process, CURLOPT_POSTFIELDS, $payload);
curl_setopt($process, CURLOPT_RETURNTRANSFER, TRUE);
$return = curl_exec($process);
curl_close($process);
//finally print your API response
print_r($return);
?>
But why are you calling your own API this way? You can simply call your API model and perform your operations

Answer 2

Add below to your curl options
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
'APIKEY: admin#123',
'Content-Type: application/json',
));
also update
$config['rest_key_name'] = 'APIKEY';
in rest.php file inside config folder of your codeigniter settings. By default it is 'X-API-KEY'
This may help to somebody else looking for a solution, if OP has resolved it himself/herself.
