How to generate token for rest call in codeigniter? - rest

Question

I have to call rest api function in codeigniter project . Data is returning from the api call using Postman . In Postman first i generate a token and put that generated token in the rest call. I have to do the same process in codeigniter. First i have to generate token and pass that token in second api call to get the desired result.
My Controller code :
public function getToken()
{
$url='http://localhost:8080/myapplication/rest/api/validate-request';
$key=$this->get_data($url);
}
public function get_data($url)
{
//create a new cURL resource
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
//curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_USERPWD, R_U_NAME.':'.R_U_PWD);
$result = curl_exec($ch);
$result = json_decode($result);
//var_dump($result);
//close cURL resource
curl_close($ch);
}
Here var_dump($result) is returning null value.

I donot had to pass username and password for authentication .Instead i had to post postman username and password in my function. Now I am getting the token back from the postman.
private function get_data($url)
{
$member_data = array(
'username' => R_U_NAME,
'password' => R_U_PWD
);
//create a new cURL resource
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $member_data);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
