facebook-graph-api - 如何在某个地点附近找到过去签到过的 friend ？

Question

在我的应用程序中，用户在一个位置并正在寻找她的 friend ，这些 friend 在她所在的地方 10 英里范围内的任何地方。如何使用 FQL 或图形找到这个？我能看到的唯一方法是运行如下搜索:https://graph.facebook.com/search?type=checkin然后运行结果以找出 10 英里内的位置。有没有更好的方法呢？

谢谢你的帮助!

它说

An FQL table that returns Posts that have locations associated with them and that satisfy at least one of the following conditions:

• you were tagged in the Post
• a friend was tagged in the Post
• you authored the Post
• a friend authored the Post

Note: This query can process a large amount of data. In order to ensure that a manageable amount of data is returned within a reasonable timeframe, you should specify a recent timestamp to narrow the results.

Return posts within 10,000 meters of a given location:

SELECT id, page_id
FROM location_post
WHERE distance(latitude, longitude, '37.86564', '-122.25061') < 10000
