Question

我可以做oldschool：

    <body>

    <div id="fb-root"></div>
    <script type="text/javascript" src="http://connect.facebook.net/de_DE/all.js"></script>

    <script type="text/javascript">

        function init(){
            FB.init({
                appId  : 'MY_APP_ID',
                status : true, // check login status
                cookie : true, // enable cookies to allow the server to access the session
                xfbml  : true, // parse XFBML
                channelUrl : 'http://MY_WEBSPACE/facebook-iframe/channel.html' // custom channel
            });
            setupApp();
        }

        function setupApp() {

            FB.getLoginStatus(
                function(response) {
                    if (!response.session) {
                        FB.ui({method: "permissions.request", "perms": ''} , getUserId);
                    } else {
                        // the user previously authorized the app
                        getUserId(response);
                        window.location = "fanAuthorized.php";
                    }
                });
            return false;
        }

        function getUserId(data){
            if(data.status !== 'notConnected' || data.session !== null){
                // the user has just authorized the app
                userId = data.session.uid;
                accessToken = data.session.access_token;
                window.location = "fanAuthorized.php";
            } else {
                // the user has just denied to authorize the app
                window.location = "fanUnauthorized.php";
            }
        }

        init();

    </script>

切换到OAuth 2让我陷入困境。我尝试了以下方法：

<!DOCTYPE html> 
<html xmlns:fb="https://www.facebook.com/2008/fbml">
    <head> 
    </head> 
<body>

    <div id="fb-root"></div>

    <script>
    window.fbAsyncInit = function() {
        FB.init({ appId: 'MY_APP_ID', 
            status: true, 
            cookie: true,
            xfbml: true,
            oauth: true
        });

        function updatePage(response) {

            if (response.authResponse) {
                // user is already logged in and connected
                window.location = "fanAuthorized.php";
            } else {
                // user is not connected or logged out
                FB.login(function(response) {
                    if (response.authResponse) {
                        window.location = "fanAuthorized.php";
                    } else {
                        // user has just cancelled login or denied permission
                        window.location = "fanUnauthorized.php";
                    }
                }, {scope:''}); 
            }
        }

        // run once with current status and whenever the status changes
        FB.getLoginStatus(updatePage);
        FB.Event.subscribe('auth.statusChange', updatePage);    
    };

    (function() {
        var e = document.createElement('script'); e.async = true;
        e.src = document.location.protocol 
        + '//connect.facebook.net/de_DE/all.js';
        document.getElementById('fb-root').appendChild(e);
    }());

    </script>

</body>

此代码将我的模态对话授权转换为弹出对话授权，在没有用户交互的情况下，弹出窗口被浏览器阻止。我希望授权对话在没有用户交互的情况下解锁，并保留在当前页面（我的Facebook粉丝页面）。有没有办法做到这一点？提前谢谢！

更新：

似乎我设法以非弹出方式实现授权对话框。授权对话框在同一窗口（而不是模式对话框）中无需用户交互打开，并且不会被浏览器阻止。在用户授权应用程序后，他被重定向到他刚刚来自的facebook粉丝页面iframe中的相同标签。然后，应用程序识别出用户已连接。如果用户取消授权，他将被重定向到粉丝页面的墙上。现在代码：

Answer 1

我刚才更新了我的问题。到目前为止，我确信无法通过使用FB.ui，JQueryUI Dialog或类似的东西在模态层中显示授权对话框。

使用OAuth 2.0的Facebook javascript授权模式对话框
