使用从 api 中提取的数据难以访问 ruby 中的整个哈希
Difficulty accessing entire hash in ruby with data pulled from api
我目前正在尝试通过 Yelp API 提取数据，但似乎只能访问一半的哈希值。
此代码：
client = Yelp::Client.new
include Yelp::V2::Search::Request
request = Location.new(
:city => 'Melbourne',
:limit => 1) response = client.search(request)
puts response
将输出
的完整哈希值
{"region"=>{"span"=>{"latitude_delta"=>0.0, "longitude_delta"=>0.0},
"center"=>{"latitude"=>28.0772451, "longitude"=>-80.6045478}},

我可以使用
访问区域信息
puts response["region"]
但我似乎无法访问哈希的其余部分？我特别想提取公司名称。我缺少什么并且需要做什么才能访问整个哈希？
businesses 好像是一个数组。像
response["businesses"][0]["name"]
将检索第一个商家的名称
