根据Facebook文档,age_range是请求用户数据时的默认属性:https: //developers.facebook.com/docs/facebook-login/permissions#reference-basic-info

当我使用" me "作为具有正确令牌的用户ID 时,这确实有效:

https://graph.facebook.com/me?fields=id%2Cname%2Cemail%2Cfirst_name%2Clast_name%2Cusername%2Cgender%2Cpicture%2Cage_range&format=json&access_token=[accessToken for required user]

{
   "id": "FACEBOOKID",
   "name": "testuser",
   "email": "testuser\u0040test.net",
   "first_name": "testuser",
   "last_name": "testuser",
   "gender": "male",
   "age_range": {
      "min": 21
   },
   "picture": {
      "data": {
         "url": "https://...",
         "is_silhouette": false
      }
   }
}

但是当我使用用户ID时,data_range为空:

https://graph.facebook.com/[FacebookId]?fields=id%2Cname%2Cemail%2Cfirst_name%2Clast_name%2Cusername%2Cgender%2Cpicture%2Cage_range&format=json&access_token=[AccessToken]*

给我回复:

{
   "id": "FACEBOOKID",
   "name": "testuser",
   "email": "testuser\u0040test.net",
   "first_name": "tftestuser",
   "last_name": "tftestuser",
   "gender": "male",
   "picture": {
      "data": {
         "url": "http://....",
         "is_silhouette": true
      }
   }
}

知道为什么吗？我在这里错过了什么？

先感谢您!

我想解决以下问题:

我有一个未来[地图[A,B]].对于所有B,我需要应用一个将B转换为Future [C]的方法,并且我想要回馈Future [Map [A​​,C]]

这是我到目前为止的代码:

def getClients(clientIds: Seq[Int]): Future[Map[Int, ClientData]] = {

  def getClientData(clientInfo: ClientInfo): Future[ClientData] = 
    clientInfo match {
      case ValidInfo(info) => getData(info)
      case _ => throw new Exception
    }

  client.getClients(clientIds) map {
    _.toMap map {
      case (clientId: Int, clientInfo: ClientInfo) =>
        getClientData(clientInfo) map {
          clientData => (clientId, clientData)
      }
    }
  }
}

此代码错误,因为它返回Iterable [Future [(Int,ClientData)]]

对于info getClients是一个thrift方法,它返回Map [Map [A​​,B]],其中Map是可变的,所以我需要首先使用toMap将它转换为不可变的映射.

预先感谢您的帮助!
