如何检索整个用户配置文件（linkedin api）

Question

Here is my current API Query:

https://api.linkedin.com/v1/people/~:(firstName,lastName)

However this only returns the first and last name.

My scope is:

r_fullprofile r_contactinfo r_emailaddress

How do I retrieve the entire users profile?

Here is my current code:

        <?php
        // Change these
        define('API_KEY',      'xxx'                                          );
        define('API_SECRET',   'xxx'                                       );
        define('REDIRECT_URI', 'xxx');
        define('SCOPE',        'r_fullprofile r_contactinfo r_emailaddress');

        // You'll probably use a database
        session_name('linkedin');
        session_start();

        // OAuth 2 Control Flow
        if (isset($_GET['error'])) {
            // LinkedIn returned an error
            print $_GET['error'] . ': ' . $_GET['error_description'];
            exit;
        } elseif (isset($_GET['code'])) {
            // User authorized your application
            if ($_SESSION['state'] == $_GET['state']) {
                // Get token so you can make API calls
                getAccessToken();
            } else {
                // CSRF attack? Or did you mix up your states?
                exit;
            }
        } else { 
            if ((empty($_SESSION['expires_at'])) || (time() > $_SESSION['expires_at'])) {
                // Token has expired, clear the state
                $_SESSION = array();
            }
            if (empty($_SESSION['access_token'])) {
                // Start authorization process
                getAuthorizationCode();
            }
        }

        // Congratulations! You have a valid token. Now fetch your profile 
        $user = fetch('GET', '/v1/people/~:(firstName,lastName)');
        print_r($user);
        print "Hello $user->firstName $user->lastName.";
        exit;

        function getAuthorizationCode() {
            $params = array(
                'response_type' => 'code',
                'client_id' => API_KEY,
                'scope' => SCOPE,
                'state' => uniqid('', true), // unique long string

                )
            );

            // Need to use HTTPS
            $url = 'https://api.linkedin.com' . $resource;

            // Append query parameters (if there are any)
            if (count($params)) { $url .= '?' . http_build_query($params); }

You must specify all of the profile fields that you want back as part of your request.

Available profile fields are listed in the official documentation here: https://developer.linkedin.com/documents/profile-fields
