如何使用facebook fql和graph

从特定位置获取好友

我试过fql作为

  SELECT uid FROM user WHERE  current_location   IN ('Chennai','Tamilnadu')   AND uid IN 
   (SELECT uid2 FROM friend WHERE uid1 = me() )

显示

  {
"data": [

  ]
}

我也获得了所有必要的许可

Answer 1

首先，current_location是一种结构，因此current_location IN ('Chennai','Tamilnadu')无效。您需要指定结构中的任何字段，即：

current_location.city
current_location.state

第二次，只会找到已授权您的应用的朋友。例如，我的一位来自伦敦的朋友正在使用Graph API Explorer。这是自推出v2.0 Facebook API以来的新功能。 Read more here

所以，这个查询：

SELECT uid, current_location 
  FROM user 
 WHERE current_location.city IN ('London')   
   AND uid IN (SELECT uid2 FROM friend WHERE uid1 = me() )

给出：

{
  "data": [
    {
      "uid": "73221xxx", 
      "current_location": {
        "city": "London", 
        "state": "England", 
        "country": "United Kingdom", 
        "zip": "", 
        "latitude": 51.5072, 
        "longitude": -0.1275, 
        "id": "106078429431815", 
        "name": "London, United Kingdom"
      }
    }
  ]
}
