I use the following code which is tested with the wordpress API and codeigniter 3. You'll need to amend the $opts array.
$method would be post, get, put ...
$url the api url ...
$opts = array('https'=>array('method'=>"GET",'header'=>"Authorization: Bearer $token"));
public function CallAPI($method, $url, $opts = false)
{
$curl = curl_init();
switch ($method)
{
case "POST":
curl_setopt($curl, CURLOPT_POST, 1);
if ($opts)
curl_setopt($curl, CURLOPT_POSTFIELDS, $opts);
break;
case "PUT":
curl_setopt($curl, CURLOPT_PUT, 1);
break;
default:
if ($opts)
$url = sprintf("%s?%s", $url, http_build_query($opts));
}
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($curl);
curl_close($curl);
return $result;
}
// The following is your code but slightly amended to change the header and suggest Authorization which is commented out. I also removed some unnecessary curl. I changed your $data_array to include the header but try it in its original form as well but with content-Type as application/json.
$url = "https://blabla.com/Auth/login";
$data_array = array('username' => $username,'password' =>
$password,'baseSessionID' => $baseSessionID,'ipAddress' => $ipAddress,
'https' => array('header' => 'Content-Type: application/json','Auth-Key:
simplerestapi', 'Client-Service: frontend-client'));
$data = http_build_query($data_array);
/*
$data1 = array(
//'Content-Type: application/x-www-form-urlencoded',
'Content-Type: application/json',
'Auth-Key: simplerestapi',
//'Authorization: Basic '. base64_encode("app_key:app_secret")
'Client-Service: frontend-client'
);
*/
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
//curl_setopt($ch, CURLOPT_HTTPHEADER, $data1);
$reply=curl_exec($ch);
if($e = curl_error($ch)){
echo $e;
}else{
echo $decode = json_decode($reply,true);
}
curl_close($ch);
