如何使用PHP在Facebook应用程序中获取用户电子邮件ID？

Question

我用PHP创建了一个简单的Facebook应用程序,用户名来迎接用户,我也想要显示电子邮件ID.但我无法做到这一点.我正在使用的代码是,

require_once('facebook.php');
require_once('config.php');
$facebook = new Facebook(APIKEY, SECRETKEY);
$user=$facebook->require_login();

echo $user; // displaying the ID
<div style="padding: 10px;" id="greeting">
   <fb:if-is-app-user uid="loggedinuser">
      <h2>Hi <fb:name firstnameonly="true" uid="loggedinuser" useyou="false"/>! welcome to facebook</h2>
  <fb:else>
       <h2>Hi <fb:name firstnameonly="true" uid="loggedinuser" useyou="false"/>! welcome to facebook</h2>
   </fb:else>
   </fb:if-user-has-added-app>
</div>

我得到的输出是,

1000002020202020
Hi User! welcome to facebook

您可以直接获取电子邮件地址,而无需使用FQL.

// initialize facebook
 $facebook = new Facebook(array(
        'appId' => APP_ID,
        'secret' => APP_SECRET));

 $session = $facebook->getSession();
 if ($session) {
 try {
    $fbme = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
  }
}
else
{
  echo "You are NOT Logged in";
}

//getting the login page if not signned in
if (!$fbme) {
  $loginUrl = $facebook->getLoginUrl(array('canvas' => 1,
                                      'fbconnect' => 0,
                                      'req_perms' =>                   'email,user_birthday,publish_stream',
                                      'next' => CANVAS_PAGE,
                                      'cancel_url' => CANVAS_PAGE ));
 echo '<fb:redirect url="' . $loginUrl . '" />';
 } else {

      // $fbme is valid i.e. user can access our app
     echo "You can use this App";
 }

 // getting the profile data
 $user_id = $fbme[id];
 $name=$fbme['name'];
 $first_name=$fbme['first_name'];
 $last_name=$fbme['last_name'];
 $facebook_url=$fbme['link'];
 $location=$fbme['location']['name'];
 $bio_info=$fbme['bio'];
 $work_array=$fbme['work'];
 $education_array=$fbme["education"];
 $email=$fbme['email'];
 $date_of_birth=$fbme['birthday'];

这段代码对我有用......我会使用电子邮件ID获取所需的所有信息.

NOTE: User has to allow us to get their Information during the Approval of Application.
