How to call a Java Rest API from PHP Codeigniter Controller? - codeigniter

Question

I have a rest service written in Spring MVC. The requirement is to call the particular service from my Codeigniter project. Here is the code I used,
function connection(){
header('Access-Control-Allow-Origin: *');
$endpoint = "http://localhost:8090/{projectName}/{rest_endpoint}";
try
{
// Get cURL resource
$curl = curl_init();
// Set some options
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => $endpoint,
CURLOPT_HTTPHEADER => ['Accept:application/json']
));
// Send the request & save response to $resp
$resp = curl_exec($curl);
// Check HTTP status code
if (!curl_errno($curl)) {
switch ($http_code = curl_getinfo($curl, CURLINFO_HTTP_CODE)) {
case 200: # OK
echo "Server JSON Response:" . $resp;
break;
default:
echo 'Unexpected HTTP code: ', $http_code, "\n";
echo $resp;
}
}
// Close request to clear up some resources
curl_close($curl);
} catch (Exception $ex) {
printf("Error while sending request, reason: %s\n",$ex->getMessage());
}
}
This does not call the Rest endpoint. Both of them are running on localhost.
