Get Request Header is missing (x-auth-token) and how to return stream format PDF?

I am developing a POST API which calling a service to return url of .pdf file. It returns {url, token and other fields}. And I want to redirect to this url and get the pdf file, but i fail.

example: url : "https://xxxxxxx.com/abc.pdf" token : "hello123"

The url is requiring request headers "X-Auth-Token"

            // post request data
            $SFOrder = [
                'reference_number' => $shipmentReferenceNumber,
                'order_id' => $orderId,
            ];

            // cloud print service and retrieve data
            $result = $this->openSFService->cloudPrintSingle($SFOrder);
            $objArray = json_decode($result['apiResultData'], true);
            $files = $objArray['obj']['files'];    

        
            // token and url
            $token = $files[0]['token'];
            $url = $files[0]['url'];

            $headers = array();
            header("Access-Control-Allow-Origin: *");
            header("Access-Control-Allow-Headers: *");
            $headers[] = "X-Auth-Token: $token";
            $headers[] = 'Content-Type: application/x-www-form-urlencoded; charset=utf-8';

            $state_ch = curl_init();
            curl_setopt($state_ch, CURLOPT_URL, $url);
            curl_setopt($state_ch, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($state_ch, CURLOPT_HTTPHEADER, $headers);
            $state_result = curl_exec($state_ch);

            // method 2:
            print_r($state_result);

            // method 1:
            header('x-Auth-Token: ' . $token);
            header("Location: " . $url); /* Redirect browser */            

            exit();

I have tired two ways:

  1. I used header("X-Auth-Token: " . $token) and header("Location: " . $url) redirect the link, but the request headers "x-auth-token" is missing , which returning 404 when I accessed the page.

  2. return stream format like below?? how to convert the content to pdf?

Solution 
  • $state_ch = curl_init();

        $headers = array();
        $headers[] = "Cache-Control: public";
        $headers[] = "x-auth-token: $token";
        
        curl_setopt($state_ch, CURLOPT_URL, $url);
        curl_setopt($state_ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($state_ch, CURLOPT_HTTPHEADER, $headers);
        $state_result = curl_exec($state_ch);

        curl_close($state_ch);

        $data = $state_result;
        header('Content-Type: application/pdf');
        header('Content-Disposition: attachment; filename="abc.pdf"');
        echo $data;

        exit();
