Question

我可以获取所有用户的详细信息，但我的网站中需要用户的用户名（在CI框架中编码）。我希望我的网站与Facebook完全集成。我使用过PHP SDK代码。下面我提供了完整的代码。如果我可以使用用户的fb id和FQL获取用户的用户名，请告诉我。

<div id="fb-root"></div>
<script type="text/javascript">
    var button;
    var userInfo;   
    window.fbAsyncInit = function() {
        FB.init({ appId: 'your app id', //change the appId to your appId
        status: true, 
        cookie: true,
        xfbml: true,
        oauth: true});

      // showLoader(true);

        function updateButton(response) {
             button       =   document.getElementById('fb-auth');
             userInfo     =   document.getElementById('user-info');

             if (response.authResponse) {
                 //user is already logged in and connected
                 FB.api('/me', function(info) {

                     login(response, info);
                     //alert(info.email);


                 });

                 button.onclick = function() {
                     FB.logout(function(response) {
                         logout(response);
                     });
                 };
             } else {
                 //user is not connected to your app or logged out
                 button.innerHTML = 'Login';
                 button.onclick = function() {
                     FB.login(function(response) {
                         if (response.authResponse) {
                             FB.api('/me', function(info) {

                             //user cancelled login or did not grant authorization

我的代码中没有看到任何php，只有javascript。

Facebook现在正在使用多个api。

使用最新版本（＆＃39; v2.1＆＃39;）

     $query = (new FacebookRequest(
                                            $facebookSession, 'GET', 'me?fields=id,name'
                                            ))->execute()->getGraphObject(GraphUser::className())->asArray();
                    $id = $query['id'];

无法使用PHP SDK获取用户的用户名
