使用fql我得到了一些照片。 Photo表包含字段place_id，其中我的大多数照片都是页面表上的page_id - 没问题。但用Instagram拍摄的照片有place_id但不对应任何页面，当我用facebook查看照片时：该地点链接到foursquare页面。
我的疑问是：如何通过place_id获得与foursquare的正确链接？因为我需要知道拍照的位置。
示例：
place_id是＆＃39; 10150673541763630＆＃39;
Facebook中的照片place link是＆＃39; https://pt.foursquare.com/v/pra%C3%A7a-da-alegria/4caf06ba39458cfa4fcbf69f＆＃39;
谢谢。

不确定您要在此处实现的目标...如果您使用Graph API查询object_id 10150673541763630，则会收到以下查询：
https://graph.facebook.com/10150673541763630?metadata=1
我添加了metadata=1参数，以便您可以看到这不是一个位置对象，而是一个类型为opengraphobject:playfoursquare:venue的Opengraph对象：

您可以使用以下查询查找Instagram为实际用户发布的所有照片：
select object_id, place_id from photo where aid in (select aid from album where name="Instagram Photos" and owner=me())
然后，您可以遍历列表并通过标准Graph API请求每张照片的详细信息，如上所示。然后，您在结果对象中找到data.location下面的位置。
或者，您可以使用Batch API一次请求多个对象（https://developers.facebook.com/docs/graph-api/making-multiple-requests/），或者用逗号连接place_ids并发出如下请求：
https://graph.facebook.com/?ids={og_place1_id},{og_place2_id}&fields=id,data.location
