我正在尝试从 Facebook 获取用户签到并放在 Google 地球/地图上，我搜索了示例，但一无所获（这里和谷歌上）。
现在我的问题是获取用户的 chekins（首先我将分别制作所有 facebook 部分，然后将使用 google earth / maps 收集），即使我请求所有权限，似乎也没有授予我的应用程序权限（用于测试目的）但仍然无法正常工作。
以下是我正在使用的代码：

FB.init({
appId: 'appidhere',

});
function updateButton(response) {
var button = document.getElementById('fb-auth');
if (response.authResponse) {
//user is already logged in and connected
var userInfo = document.getElementById('user-info');
FB.api('/me', function(response) {
userInfo.innerHTML = '<img src="https://graph.facebook.com/' + response.id + '/picture">' + response.name;
button.innerHTML = 'Logout';
//checkin_id, author_uid, page_id, app_id, post_id, coords, timestamp, tagged_uids, message
var query = FB.Data.query('SELECT page_id, coords, tagged_uids, message FROM checkin WHERE author_uid= me()', response.id);
query.wait(function(rows) {
document.getElementById('user-checkins').innerHTML =
'Place: ' + rows[0].page_id + "<br />" +

它显示图片和名称，但不显示签入信息。控制台显示：

其他事情，
由于有几个签到，我如何与他们做一个循环？
在每个签入中，坐标是一个数组，我如何将这个数组转换为纬度/经度？
page_id 给了我一个 id（当然）我喜欢得到这个地方的名字，怎么做？
如果有人可以帮助我，现在谢谢你。
