php - How to get/set Header in Rest Server API? -

i have chriskacerguis rest server ,that listen client request api server do. base on client request want send/response data client in header only.

my questions are:

1. how access client header first?
   
   then
   

2. how set header in rest server?

this how send request rest server:

function request_curl($url = null) {         $utc = time();         $post = "id=1&customerid=1&amount=2450&operatorname=jondoe&operator=12";         $header_data = array(             "content-type: application/json",             "accept: application/json",             "x-api-key:3ecbcb4e62a00d2bc58080218a4376f24a8079e1",             "x-utc:" . $utc,         );         $ch = curl_init();         $curlopts = array(             curlopt_url => 'http://domain.com/customapi/api/clientrequest',             curlopt_returntransfer => true,             curlopt_httpheader => $header_data,             curlopt_followlocation => true,             curlopt_post => true,             curlopt_postfields => $post,             curlopt_header => 1,         );         curl_setopt_array($ch, $curlopts);         $answer = curl_exec($ch);         // if there error, show         if (curl_error($ch)) {             die(curl_error($ch));         }          curl_close($ch);         echo '<pre>';         print_r($answer);         echo '</pre>';     } 

below rest server function listen request , response header:

public function clientrequest_post() {         // getting post data         $entitybody = file_get_contents('php://input', 'r');        $this->response($entitybody,200);       //getting header data ,no idea      } 

may try php function getallheaders() fetch header data you. if want convert array, use foreach.

so header data , convert array

$headers=array(); foreach (getallheaders() $name => $value) {     $headers[$name] = $value; } 

now if want body , convert array well

$entitybody = file_get_contents('php://input', 'r'); parse_str($entitybody , $post_data); 

the final function this...

public function clientrequest_post() {      $headers=array();     foreach (getallheaders() $name => $value) {         $headers[$name] = $value;     }      $entitybody = file_get_contents('php://input', 'r');     parse_str($entitybody , $post_data);       $this->response($entitybody, 200);   } 

btw, assume $this->response($entitybody,200); generate response you. best of luck it
