Php Curl headers not being set - php

Question

I am trying to set 2 variables to the curl headers and can't seem to see what's wrong. I am not receiving any errors in the php logs, but when I print out the curl info I can see that the headers are not being set. Any point in the right direction would be helpful. Thanks
The Example I'm using
PHP cURL custom headers
class GetAuctions
{
private $APIKeyID = "theIDhere";
private $APIKeyPass = "thePasswordHere";
private $BaseURL = "https://someurlHere";
public function __construct()
{
//get list of upcoming auctions
$get_data = $this->callAPI('GET', $this->BaseURL, false);
//turn the response into a json
$response = json_decode($get_data, true);
//display the response for testing
echo print_r($response);
$errors = $response['response']['errors'];
$data = $response['response']['data'][0];
echo print_r($data);
}
function callAPI($method, $url, $data){
$curl = curl_init();
switch ($method){
case "POST":
curl_setopt($curl, CURLOPT_POST, 1);
if ($data)
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
break;
case "PUT":
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "PUT");
if ($data)
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
break;
default:
if ($data)
$url = sprintf("%s?%s", $url, http_build_query($data));
}
// OPTIONS:
curl_setopt($curl, CURLOPT_URL, $url);
$headers =array();
$headers['apiKeyID'] = $this->APIKeyID;
$headers['apiKeyPass'] = $this->APIKeyPass;
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
echo "<br/>";
echo print_r(curl_getinfo($curl));
echo "<br/>";
// EXECUTE:
$result = curl_exec($curl);
if(!$result){die("Connection Failure");}
curl_close($curl);
return $result;
}
}
I've also tried this:
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
"apiKeyID: $this->APIKeyID",
"apiKeyPass: $this->APIKeyPass"
));
My response looks like this:
Array ( [url] => https://MyURLHere [content_type] => [http_code] => 0 [header_size] => 0 [request_size] => 0 [filetime] => -1 [ssl_verify_result] => 0 [redirect_count] => 0 [total_time] => 0 [namelookup_time] => 0 [connect_time] => 0 [pretransfer_time] => 0 [size_upload] => 0 [size_download] => 0 [speed_download] => 0 [speed_upload] => 0 [download_content_length] => -1 [upload_content_length] => -1 [starttransfer_time] => 0 [redirect_time] => 0 [redirect_url] => [primary_ip] => [certinfo] => Array ( ) [primary_port] => 0 [local_ip] => [local_port] => 0 ) 1

Answer 1

It looks like your headers are incorrectly formatted:
"apiKeyID : $this->APIKeyID",
You should remove space before your colon:
"apiKeyID: ${this->APIKeyID}",
BTW: for debugging purpose you may also use CURLOPT_VERBOSE to see what's is being send by cURL. If you cannot peek stderr at runtime, redirect it to the file:
curl_setopt($c, CURLOPT_STDERR, fopen('curl-log.txt', 'w+'));
