I have finally found the solution and below is the approach
First we need get to LWSSO_COOKIE_KEY,QCSession,ALM_USER,XSRF_TOKEN values from the ALM Authentication link then we should use the values for subsequent calls
Below is the complete working code to get the list of defects by entering ALM Credentials
<?php
$curl = curl_init();
Header('Content-type: application/json');
$credentials = "username:password";
curl_setopt_array($curl, array(
CURLOPT_URL => "https://host:port/qcbin/api/authentication/sign-in",
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HEADER => 1,
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_SSL_VERIFYHOST => 0,
CURLOPT_SSL_VERIFYPEER => 0,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => array(
"authorization: Basic " . base64_encode($credentials) ,
"cache-control: no-cache"
) ,
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err)
{
echo "cURL Error #:" . $err;
}
else
{
// If there is no error then get the response to form the array of headers to get the different values required
$array_start = explode(';', $response);
foreach ($array_start as $key => $value) {
$remove_from_string = ['HTTP/1.1 200 OK','Path=/','HTTPOnly','HttpOnly','Content-Length',': 0'];
$replace_array = ['','','','','',''];
$value = str_replace($remove_from_string,$replace_array,$value);
$value = trim(preg_replace(('/Expires: [a-zA-Z]+, [0-9]+ [a-zA-Z]+ [0-9]+ [0-9]+:[0-9]+:[0-9]+ [a-zA-Z]+/'), '', $value));
$value = trim(preg_replace(('/Server: [a-zA-Z0-9.\(\)]+/'),'',$value));
if (!empty($value)) {
$almheaders[trim(explode('=',$value)[0])] = explode('=',$value)[1];
}
}
$LWSSO_COOKIE_KEY = $almheaders['Set-Cookie: LWSSO_COOKIE_KEY'];
$QCSession = $almheaders['Set-Cookie: QCSession'];
$ALM_USER = $almheaders['Set-Cookie: ALM_USER'];
$XSRF_TOKEN = $almheaders['Set-Cookie: XSRF-TOKEN'];
// Now form the Cookie value from the above values.
$cookie = "Cookie: JSESSIONID=33eyr1y736486zcnl0vtmo12;XSRF-TOKEN=$XSRF_TOKEN;QCSession=$QCSession;ALM_USER=$ALM_USER;LWSSO_COOKIE_KEY=$LWSSO_COOKIE_KEY";
// echo $cookie;
$curl = curl_init();
Header('Content-type: application/json');
curl_setopt_array($curl, array(
CURLOPT_URL => "https://host:port/qcbin/api/domains/CET_NTD/projects/BILLING_OPERATIONS/defects",
// CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HEADER => 0,
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_SSL_VERIFYHOST => 0,
CURLOPT_SSL_VERIFYPEER => 0,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => array(
"authorization: Basic " . base64_encode($credentials) ,
"cache-control: no-cache",
"Accept: application/json",
$cookie
) ,
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err)
{
echo "cURL Error #:" . $err;
}
else
{
echo $response;
}
}
?>
