我从一些关于链接注册的教程中获得了这段代码，但该教程只提供了基本信息。我还需要获取用户电子邮件...我该怎么做？
这是代码：
授权文件
这是我在 likedin 上获取访问表单的链接。
<?php
session_start();
$config['base_url'] = '';
$config['callback_url'] = '';
$config['linkedin_access'] = '';
$config['linkedin_secret'] = '';
include_once "linkedin.php";
# First step is to initialize with your consumer key and secret. We'll use an out-of-band oauth_callback
$linkedin = new LinkedIn($config['linkedin_access'], $config['linkedin_secret'], $config['callback_url'] );
//$linkedin->debug = true;
# Now we retrieve a request token. It will be set as $linkedin->request_token
$linkedin->getRequestToken();
$_SESSION['requestToken'] = serialize($linkedin->request_token);
# With a request token in hand, we can generate an authorization URL, which we'll direct the user to
//echo "Authorization URL: " . $linkedin->generateAuthorizeUrl() . "\n\n";
header("Location: " . $linkedin->generateAuthorizeUrl()); ?>
演示.php
这是我注册后得到的脚本。
<?php
session_start();
$config['base_url'] = 'http://xxx/linkedin/auth.php';
$config['callback_url'] = 'http://xxx/linkedin/demo.php';
$config['linkedin_access'] = '';
$config['linkedin_secret'] = '';
include_once "linkedin.php";
# First step is to initialize with your consumer key and secret. We'll use an out-of-band oauth_callback
$linkedin = new LinkedIn($config['linkedin_access'], $config['linkedin_secret'], $config['callback_url'] );
//$linkedin->debug = true; if (isset($_REQUEST['oauth_verifier'])){
$_SESSION['oauth_verifier'] = $_REQUEST['oauth_verifier'];
$linkedin->request_token = unserialize($_SESSION['requestToken']);
$linkedin->oauth_verifier = $_SESSION['oauth_verifier'];
$linkedin->getAccessToken($_REQUEST['oauth_verifier']);
$_SESSION['oauth_access_token'] = serialize($linkedin->access_token);
header("Location: " . $config['callback_url']);
exit;} else{
$linkedin->request_token = unserialize($_SESSION['requestToken']);
$linkedin->oauth_verifier = $_SESSION['oauth_verifier'];
$linkedin->access_token = unserialize($_SESSION['oauth_access_token']);}
# You now have a $linkedin->access_token and can make calls on behalf of the current member
$xml_response = $linkedin->getProfile("~:(id,first-name,last-name,headline,picture-url)");
$id = $linkedin->getProfile('~:(id)');
$fname = $linkedin->getProfile('~:(first-name)');
$lname = $linkedin->getProfile('~:(last-name)');
$headline = $linkedin->getProfile('~:(headline)');
$picture = $linkedin->getProfile('~:(picture-url)');
$id = trim(strip_tags($id));
$fname = trim(strip_tags($fname));
$lname = trim(strip_tags($lname));
$headline = trim(strip_tags($headline));
