Facebook FB.ui 注销不会触发

Question

FB.ui(
       {
         method: 'feed',
         name: 'some text',
         link: 'some text',
         picture: 'aa.jpg',
         caption: 'some text',
         description: 'some text',
         message: 'some text'
       },
       function(response) {
         if (response && response.post_id) {
            alert('Post was published.');               
        } else {
            alert('Post was not published.');
         }
       });
}

该代码工作正常，现在我喜欢之后:

alert('Post was published.');

静默地从 Facebook 注销怎么办？

添加该代码 alert('postpublish') 后没有执行任何操作!

FB.ui(
 { method:'auth.logout',  display:'hidden' },
 function() { alert("you're logged out!"); }
);

我发现:FB auth.logout is being raised after being logged in using the "server-side-workflow" (OAuth 2.0)但不确定我是否足够理解代码以知道它执行我的要求!

Best Practices

FB.logout will log the user out of both your site and Facebook. You will need to have a valid access token for the user in order to call the function.

Calling FB.logout will also invalidate the access token that you have for the user, unless you have the offline_access permission.

我使用评论框编写了一个示例来触发自动注销 http://shawnsspace.com/fb.logout.test.php

代码:

<小时/>

    <div id="fb-root"></div>    
    <script>
      window.fbAsyncInit = function() {
        FB.init({
    appId  : '112104298812138',
    status : true, // check login status
    cookie : true, // enable cookies to allow the server to access the session
    xfbml  : true, // parse XFBML
    //channelUrl : 'http://WWW.MYDOMAIN.COM/channel.html', // channel.html file
    oauth  : true // enable OAuth 2.0
        });
FB.Canvas.EarlyFlush.addResource("http://shawnsspace.com/index.php");
FB.Canvas.setAutoResize();
            FB.getLoginStatus(function(response) {
              if (response.authResponse) {

                var accessToken = response.authResponse.accessToken;
              } else {
              }
            }); 
    FB.Event.subscribe('comment.create', function(response) {
     //alert(JSON.stringify(response));
        FB.logout(function(response) {
        window.location.reload();
        });
    });
        FB.Event.subscribe('auth.login', function(response) {
        //top.location.href = 'http://apps.facebook.com/shawnsspace/fbcomments.php?ref=loggedin';
        window.location.reload();
        });
        FB.Event.subscribe('auth.logout', function(response) {
        //top.location.href = "http://apps.facebook.com/shawnsspace/fbcomments.php?ref=loggedout";
        alert('logged out');
        });
      };
      (function() {
        var e = document.createElement('script'); e.async = true;
        e.src = document.location.protocol +
          '//connect.facebook.net/en_US/all.js';
        document.getElementById('fb-root').appendChild(e);
      }());
</script>
