並放入SCV。JSON如何解析只需一鍵 - 中的散列值

怎麼辦？請幫我...

假設WeeklyTrafficNumbers是一個在返回的JSON中，你只需要把它作爲你的行： puts weekly = JSON.parse（page.body.match（/Sw.preloadedData =（。*）; \ n /）[''WeeklyTrafficNumbers '] – ABrowne

你的例子不工作 – user3426145

沒有看到完整的JSON轉儲它不可能告訴你什麼是關鍵然而，作爲一個例子，是它是如何完成的： json = {'h'：9，'g '：{'y'：5}}。如果你想得到h，你可以鍵入json ['h']，但是如果你想要的話，你會輸入json ['g'] ['y']，因爲它的兩個級別在g – ABrowne

這應該工作：

require 'csv' 
require 'json' 

weekly = JSON.parse(page.body.match(/Sw.preloadedData = (.*);\n/)[1]['overview']['WeeklyTrafficNumbers'] 
weekly = { 'WeeklyTrafficNumbers' => weekly } 


CSV.open("your_csv.csv", "w") do |csv| #open new file for write 
    weekly.each do |hash| #open json to parse 
    csv << hash.values #write value to file 
    end 
end

puts weekly = JSON.parse（page.body.match（/Sw.preloadedData =（。*）; \ n /）[1]）['overview'] ['TrafficSources'] ['WeeklyTrafficNumbers'] 這是什麼都不顯示。我運行並在控制檯顯示一個空字符串。多數民衆贊成在所有=（ – user3426145

更新答案，並添加了CSV功能（我猜你是指CSV而不是SCV） – SickLickWill

這是你想要的數據的正確路徑：

irb> weekly = JSON.parse(page.body.match(/Sw.preloadedData = (.*);\n/)[1])['overview']['WeeklyTrafficNumbers'] 
=> {"2015-08-01"=>1822718149, "2015-09-01"=>1827876529, "2015-10-01"=>1891870292, "2015-11-01"=>1864311156, "2015-12-01"=>1858168664, "2016-01-01"=>1828491727}

它的WeeklyTrafficNumbers的實際價值了，所以錯過了包裝：

weekly = { 'WeeklyTrafficNumbers' => weekly }

是的，你是對的包裝。 – SickLickWill
