Q:

Jira API getting attachment

I've written some code that displays a list of attachments.  The problem is, though, that I want the user to be able to view the attachment without being logged in.  Is there a way to authenticate for the user?  Here is my code:
 //to get cases.  this returns a list of attachments, with the url in Jira

  $attachments = $jira_case->issues[0]->fields->attachment;

   //iterates over the lists and creates links
   foreach ($attachments as $i=> $attachment) {
      $html .="
      <tr>
          <td style='padding-left: 10px; width:0px; padding-top: 20px;' colspan='3'>
          ". ($i+1) .") <a target = '_blank' href ='". $attachment->content ."'>". nl2br($attachment->filename) ."</a>
          </td>
     </tr>";
}

The problem is that when the user clicks the link, if they are not logged in, they will be requested to log in.  I don't want this, as it is my app the authenticates so that the user does not need a jira account.  Is this possible?  Maybe by passing some sort of token?

In case anyone else wonders how to do this:   
$url = "https://mySite.atlassian.net/secure/attachment/". $attachment_id ."/". $attachment_name ."?os_username=". $this->jira_user_name ."&os_password=" . $this->jira_password;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

$file = curl_exec($ch);
curl_close($ch);

if($file){
     header('Content-Description: File Transfer');
     header('Content-Type: application/octet-stream');
     header('Content-Disposition: attachment; filename='.$attachment_name);
     header('Expires: 0');
     header('Cache-Control: must-revalidate');
     header('Pragma: public');
     echo ($file);
     exit;
}else{
     throw new Exception("Error:  file now found.");
}
