Facebook OAuth2.0实现

Question

我对Facebook的实现还是个新手。请帮助我使用OAuth2.0通过新的all.js实现这段代码

 window.addEvent('domready', function(){     
 FB.init("<%= ConfigurationManager.AppSettings["ApiKey"].ToString() %>", 
         "/xd_receiver.htm",
         {"ifUserConnected": update_user_is_connected,
          "ifUserNotConnected": update_user_is_not_connected,
          "doNotUseCachedConnectState":"true"});
});

这个问题并没有真正解释太多，但猜测一下，应该是这样的(我不熟悉旧的api，所以我不知道您是否必须向update_user_is_connected/ not _connected传递任何参数，请相应地修改它)：

window.fbAsyncInit = function() {
    FB.init({
        appId  : '<%= ConfigurationManager.AppSettings["ApiKey"].ToString() %>',
        status : true, // check login status
        cookie : true, // enable cookies to allow the server to access the session
        xfbml  : true,  // parse XFBML
        channelUrl  : 'http://www.yourdomain.com/channel.html', // Custom Channel URL
        oauth : true //enables OAuth 2.0
    });

    FB.getLoginStatus(function(response) {
        if (response.authResponse) update_user_is_connected();
        else update_user_is_not_connected();
    });

    // This will be triggered as soon as the user logs into Facebook (through your site)
    FB.Event.subscribe('auth.login', function(response) {
        update_user_is_connected();
    });
};
