在 javascript 中获取应用程序用户

我正在尝试在 javascript sdk 中获取应用程序用户。为什么这不起作用？

var q = FB.Data.query('SELECT uid FROM user WHERE uid IN '
            + '(SELECT uid2 FROM friend WHERE uid1 = me()) AND is_app_user = 1');

q.wait(function(resp) {
        console.log(resp);
    }
);

返回 []

但是效果很好：

var q = FB.Data.query('SELECT uid2 FROM friend WHERE uid1 = me()');
q.wait(function(resp) {
        var l = [];
        for (var i in resp) {
            l.push(resp[i].uid2)
        }
        var fql = 'SELECT uid FROM user WHERE uid IN (' + l.join(',') + ') and is_app_user = 1';
        var q1 = FB.Data.query(fql);
        q1.wait(function(resp) {
            console.log(resp);
        });
    }
);

第二个语句的问题在于将所有朋友加载到浏览器中，并且它又发出了一个请求。为什么第一个语句不起作用？

I'm trying to get app users in javascript sdk.
Why this is not working?

var q = FB.Data.query('SELECT uid FROM user WHERE uid IN '
            + '(SELECT uid2 FROM friend WHERE uid1 = me()) AND is_app_user = 1');

q.wait(function(resp) {
        console.log(resp);
    }
);

That returns []

However that works well:

var q = FB.Data.query('SELECT uid2 FROM friend WHERE uid1 = me()');
q.wait(function(resp) {
        var l = [];
        for (var i in resp) {
            l.push(resp[i].uid2)
        }
        var fql = 'SELECT uid FROM user WHERE uid IN (' + l.join(',') + ') and is_app_user = 1';
        var q1 = FB.Data.query(fql);
        q1.wait(function(resp) {
            console.log(resp);
        });
    }
);

The problem with the second statement is that loads all friends into browser and it makes one more request. Why isn't the first statement working?

尝试将 is_app_user 视为布尔值：
（仅使用 fql 对我有用）

var q = FB.Data.query('SELECT uid FROM user WHERE uid IN '
+ '(从朋友中选择 uid2，其中 uid1 = me()) AND is_app_user');

尝试 FB.api。请参阅旧 REST API 调用部分：

FB.API 还可用于调用旧 REST API。为了
例如，调用 links.getStats：
<前><代码>FB.api(
{
方法：'links.getStats',
网址：'facebook.com，developers.facebook.com'
},
函数（响应）{
警报（
'总计：' + (响应[0].total_count +
响应1.total_count));
}
）；

上面 + fql.query = 成功:)

Try FB.api. See section: Old REST API calls:

FB.API can also be used to invoke calls to the Old REST API. For
example, to call links.getStats:
FB.api(
  {
    method: 'links.getStats',
    urls: 'facebook.com,developers.facebook.com'
  },
  function(response) {
    alert(
      'Total: ' + (response[0].total_count +
response1.total_count));
}
);

Above + fql.query = success:)
