Rubyで楽天APIとホットワードAPIを使ってみた

korekae.rb

# encoding: utf-8

require "open-uri"
require "nokogiri"

class Korekae
	def index
		url = "http://kizasi.jp/kizapi.py?type=rank"
		xml = open(url).read
		doc = Nokogiri::XML(xml)
		trend_words = []
		companies = []
		doc.search("item").search("title").each do |item|
			shopNames = rakutenAPI(item.inner_text)
			if shopNames.empty?
				next
			end
			companies[0,0] = shopNames # 配列に配列要素を追加
			trend_words.push(item.inner_text)
		end
		return {:company => companies,:trend => trend_words}
	end
	#トレンド単語から株を買うべきお店を提示
	def rakutenAPI(keyword)
		sleep(1.5)
		# applicationId = YOUR_APP_ID_HERE
		base_url = "https://app.rakuten.co.jp/services/api/IchibaItem/Search/20140222?applicationId=YOUR_APP_ID_HERE"
		param = "&keyword="+URI.encode(keyword)+"&format=xml"
		url = base_url + param
		xml = open(url).read
		doc = Nokogiri::XML(xml)
		shopNames = []
		doc.search("shopName").each do |shop|
			shopNames.push(shop.inner_text)
		end
		return shopNames
	end
end

# 表示
kae = Korekae.new
hash = kae.index
trend_words = hash[:trend]
companies = hash[:company]
trend_words.each do |word|
	p "・"+word
end
companies.each do |company|
	p "@"+company
end
