问题描述
我目前正在开发一个Android应用程序，使用Facebook的图形API来获取基于用户的位置页/地方。我也想通过分类筛选结果，如餐馆为例。现在我只是在寻找命名为餐厅是这样的：<一href="https://graph.facebook.com/search?q=restaurant&type=place¢er=37.76,-122.427&distance=1000" rel="nofollow">https://graph.facebook.com/search?q=restaurant&type=place¢er=37.76,-122.427&distance=1000
I'm currently developing an Android app that uses Facebook graph API to get pages/places based on user's location. I also want to filter the results by category, like restaurants for example.For now I'm just searching for the name "restaurant" like this:https://graph.facebook.com/search?q=restaurant&type=place¢er=37.76,-122.427&distance=1000
现在的问题是，它不会找到没有名字餐厅的网页/地方，它也返回鸵鸟政策有什么用餐馆的地方。我也有语言问题，在非英语国家我的搜索将完全失败。
The problem is that it wont find pages/places that don't have name "restaurant" and it also returns places that don´t have anything to do with restaurants. I also have the language issue, in non-English countries my search will fail completely.
一个可能的解决方案我正在考虑是要在一个范围内的所有地方，并分析它们在我的应用程序的类别或名称。显然，这带来了很大的开销，以我的应用程序。
A possible solution I am considering is to get all the places in a range and parse them in my app for the category or name. Obviously this brings a lot of overhead to my app.
我在想，如果有喜欢用FQL得到过滤效果更好的解决办法？
I was wondering if there is a better solution like using FQL to get filtered results?
推荐答案
应该有，但我不能解开如何。
There should be, but I can't unravel how.
这FQL查询，将让你对附近的一个已知位置的所有场所的信息：
This FQL query will get you information about all places near a known location:
SELECT name, page_id, categories, description, general_info
FROM page WHERE page_id IN
(SELECT page_id FROM place WHERE
distance(latitude, longitude, "37.76", "-122.427") < 1000
)
在类别字段与值的数组 ID 和名称。看着这些结果，有一系列类别的名称，如餐厅的：意大利餐厅，酒吧/餐厅等
The categories field is an array with the values id and name. Looking at these results, there are a series of category names like "Restaurant": "Italian Restaurant", "Bar/Restaurant, etc.
我不能找到一种方法来一个在类别子句添加到这个返回数据。
What I can't find is a way to add a WHERE categories clause to this that returns data.
