我试图发布到一个连接的用户使用javascript sdk的facebook墙，这里是我的代码：

var connecter=false;
  window.fbAsyncInit = function() {
    FB.init({
      appId      : 'xxxxxxx', // App ID
      oauth      : true,
      channelUrl : '//www.streamazing.net/js/channel.html', // Channel File
      status     : true, // check login status
      cookie     : true, // enable cookies to allow the server to access the session
      xfbml      : true  // parse XFBML
    });

    FB.Event.subscribe('auth.login', function (response) {
               window.location.reload();
            });

    FB.Event.subscribe('auth.logout', function (response) {
               window.location.reload();
            });


    FB.getLoginStatus(function(response) {
            if (response.status === 'connected') {
                connecter=true;
                FB.api('/me', function(user) {
                var user2=user;
                console.log(user2.name);

                });

            }
        else connecter=false;
        });



    var body = 'This is a test';
                FB.api('/me/feed', 'post', { message: body }, function(response) {
                    if (!response || response.error) {
                        console.log(response.error);
                    } else {
                        alert('Post ID: ' + response.id);
                    }
                });
};

下面是控制台日志：

code: 2500
message: "An active access token must be used to query information about the current user."
type: "OAuthException"

我用这个代码请求许可：

<fb:login-button autologoutlink='true'  scope='email,user_birthday,status_update,publish_stream'></fb:login-button>

我不明白为什么facebook问我一个访问令牌，有人能帮我吗？非常感谢。
