I'm finalising something for a uni project that requires OAuth Intergration, I'm having issues with Curl, it appears like I've copied my reference material okay but where my lecturers can get this authorisation working I can't seem to, here is the relevant code and stack trace:
Thanks in advance!
Fatal error: Uncaught TypeError: curl_setopt(): The CURLOPT_HTTPHEADER option must have an array value in /mnt/sdb1/home/18011506/public_html/BSCHons/WP/A1/OAuth.class.php:11 Stack trace: #0 /mnt/sdb1/home/18011506/public_html/BSCHons/WP/A1/OAuth.class.php(11): curl_setopt() #1 /mnt/sdb1/home/18011506/public_html/BSCHons/WP/A1/OAuth.class.php(53): CurlHandler->__construct() #2 /mnt/sdb1/home/18011506/public_html/BSCHons/WP/A1/OAuth.class.php(151): OAuth->getAuth() #3 /mnt/sdb1/home/18011506/public_html/BSCHons/WP/A1/OAuth.class.php(144): ProviderHandler->processCode() #4 /mnt/sdb1/home/18011506/public_html/BSCHons/WP/A1/index.php(12): ProviderHandler->performAction() #5 {main} thrown in /mnt/sdb1/home/18011506/public_html/BSCHons/WP/A1/OAuth.class.php on line 11

I have tried the following and neither have worked
<?php
public function getAuth($code) {
$curl = new CurlHandler($this->tokenURL);
$headers = array('Accept: application/json');
$curl->setHeader($headers);
// Rest of the code...
}
public function setHeader($header) {
if (is_array($header)) {
curl_setopt($this->curl, CURLOPT_HTTPHEADER, $header);
} else {
curl_setopt($this->curl, CURLOPT_HTTPHEADER, array($header));
}
}
?>`
You are passing curl header as value. But it should be passed as key-value pair that means array with key value should be passed there. You can try the value code
class CurlHandler {
public $curl;
public function __construct($url=''){
$this->curl = curl_init($url);
curl_setopt($this->curl, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);
curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($this->curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
//curl_setopt($this->curl, CURLOPT_HTTPHEADER, 'Content-Type: application/x-www-form-urlencoded');
$this->setPost();
}
public function setHeader($header) {
curl_setopt($this->curl, CURLOPT_HTTPHEADER, $header);
}
public function setPost($value = true) {
curl_setopt($this->curl, CURLOPT_POST, $value);
}
public function setQuery($query = []){
curl_setopt($this->curl, CURLOPT_POSTFIELDS, http_build_query($query));
}
public function runCurl() {
return curl_exec($this->curl);
}
}
Now call the CurlHandler class by passing headers in setHeader() method.
$curl = new CurlHandler($this->tokenURL);
$headers = array(
'Content-Type: application/x-www-form-urlencoded',
);
$curl->setHeader($headers);
