Question

我试图用四平方API 建立一个小应用程序。

require  rubygems 
require  rest-client 
require  json 
require  foursquare2 
require  awesome_print 

client = Foursquare2::Client.new(:client_id =>  xxx , :client_secret =>  xxx )

response = client.search_venues(:ll =>  36.142064,-86.816086 , :query =>  nails )

不过我从API得到的反应却令人费解!

[
    [0] "groups",
    [1] [
        [0] {

                },

以上是答复的第一部分,许多数据都回来了。

Ruby拿出你想要的分数的最佳方法是什么?例如,如果我要每个结果的名字回来的话?

回应的类别是Hashie:我以前从未见过的马什?

Answer 1

哈希给你一些糖与哈希斯玩(见https://github.com/intrida/hashie )。

要获得每个结果的名称, 类似的东西应该可以做这个把戏:

response.groups[0].items.each{|i| puts i.name}
