Php soundcloud无法获取电子邮件

我正在使用soundcloud登录php脚本，我无法在我的代码下面获得电子邮件值

$soundcloud = new Services_Soundcloud($clientId, $clientSecret, $callback);
try {
   $accessToken = $soundcloud->accessToken($_GET['code']);
} catch (Services_Soundcloud_Invalid_Http_Response_Code_Exception $e) {
    exit($e->getMessage());
}
try {
    $me = json_decode($soundcloud->get('me'), true);
} catch (Services_Soundcloud_Invalid_Http_Response_Code_Exception $e) {
    exit($e->getMessage());
}

$user_data = array(
                'access_token' => $accessToken['access_token'],
                'id' => $me['id'],
                'username' => $me['username'],
                'name' => $me['full_name'],
                'email' => $me['email'],
                'avatar' => $me['avatar_url']
            );

print_r($user_data );

变量

$me

中包含什么？您能显示

打印（$me）

$me

变量中找不到电子邮件。您如何访问？如果没有任何名为

电子邮件的字段，那么您如何检索？对不起！我不知道什么是soundcloud？
