使用ruby輕鬆訪問陣列中的哈希值

我使用ruby從Google geocode API獲取一些地址信息。我得到JSON返回並解析這個變量是一個包含哈希的數組。使用ruby輕鬆訪問陣列中的哈希值

我解析的JSON之後，它看起來像這樣

{"status"=>"OK", 
"results"=> 
    [{"address_components"=> 
    [{"long_name"=>"XXX", "types"=>["street_number"], "short_name"=>"XXX"}, 
     {"long_name"=>"St Georges Terrace", 
     "types"=>["route"], 
     "short_name"=>"St Georges Terrace"}, 
     {"long_name"=>"Perth", 
     "types"=>["locality", "political"], 
     "short_name"=>"Perth"}, 
     {"long_name"=>"Western Australia", 
     "types"=>["administrative_area_level_1", "political"], 
     "short_name"=>"WA"}, 
     {"long_name"=>"Australia", 
     "types"=>["country", "political"], 
     "short_name"=>"AU"}, 
     {"long_name"=>"6000", "types"=>["postal_code"], "short_name"=>"6000"}], 
    "types"=>["street_address"], 
"geometry"=> 
{"location_type"=>"ROOFTOP", 
    "viewport"=> 
    {"northeast"=>{"lng"=>115.86768092068, "lat"=>-31.9540383793198}, 
    "southwest"=>{"lng"=>115.86138567932, "lat"=>-31.9603336206802}}, 
    "location"=>{"lng"=>115.8645333, "lat"=>-31.957186}}, 
"formatted_address"=>"XXX St Georges Terrace, Perth WA 6000, Australia"}]}

我的紅寶石看起來像這樣

require 'rubygems' 
require 'json' 
require 'open-uri' 
require 'pp' 

@url = "http://maps.googleapis.com/maps/api/geocode/json?address=PERTH+XXX+St+Georges+Terrace,+Western+Australia&sensor=false" 

uri = URI.parse(@url) 
json = uri.open.read 

parsed_json = JSON.parse(json) 

pp parsed_json

hashjes和數組的混合物困惑我的紅寶石。我希望將信息提取到一個散列中，看起來像這樣

result = {「address_line_one」=>「XXX St Georges Terrace」，「address_line_two」=>「Perth」，「state」=>「Western Austalia 」，「POSTAL_CODE」=> 「6000」}

由於

j = parsed_json 
a = j['results'][0]['address_components'].map { |e| e['long_name'] } 

p(
    { 'address_line_one' => a[0..1].join(' '), 
    'address_line_two' => a[2], 
    'state'   => a[3], 
    'postal_code'  => a[5] } 
)
