Question

我正在使用以下代码来捕获事件，如果用户已经喜欢您的页面但它不起作用。总是那个用户不喜欢你的页面。

window.fbAsyncInit = function（）{ FB.init（{ appId：＆＃39; app_id＆＃39;，//应用ID channelURL：＆＃39;路径＆＃39;，//频道文件网址 status：true，//检查登录状态 cookie：true，//启用cookie以允许服务器访问会话 oauth：true，//启用OAuth 2.0 xfbml：true //解析XFBML }）;

                FB.getLoginStatus(function(response) {
                    console.log(response);
                    if (response.authResponse) {
                        // logged in and connected user, someone you know
                        var user_id = response.authResponse.userID;
                        var page_id = "1457622007810260";
                        var fql_query = "SELECT uid FROM page_fan WHERE page_id = "+ page_id + " and uid= "+ user_id ;
                        var the_query = FB.Data.query(fql_query);
                        alert(fql_query);
                        alert(user_id);
                        the_query.wait(function(rows) {
                            alert(rows);
                            if (rows.length == 1 && rows[0].uid == user_id) {
                                //user likes the page
                                //do your stuff here
                                alert('likes');
                            } else {
                                // user doesn't like our page yet
                                alert('unlikes');
                            }
                        });
                    } else {
                        // no user session available, someone not known, not logged into fb'
                        alert('no');
                    }
                });
            };

            // Load the SDK Asynchronously
            (function(d){
                var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
                js = d.createElement('script'); js.id = id; js.async = true;
                js.src = "//connect.facebook.net/en_US/all.js";
                d.getElementsByTagName('head')[0].appendChild(js);
            }(document));

和html中的某个地方

用户需要授予user_like permisison。这要求您的申请提交给Facebook.com并由其审核

https://developers.facebook.com/docs/facebook-login/permissions/v2.0

如果你想获得一个页面的所有粉丝，你需要我认为的page_management权限。

Facebook展示了如何通过以下方式执行此计划：

如果用户已经喜欢任何Facebook页面，则捕获事件
