如何在Rails 6中遍历HTTP响应

require 'net/http'

url = URI.parse('http://example.com')
http = Net::HTTP.new(url.host, url.port)
response = http.get(url.path)

body = response.body

data = JSON.parse(response.body)
data.each do |item|
  # 遍历每个item并进行处理
end

require 'nokogiri'

doc = Nokogiri::XML(response.body)
doc.xpath('//element').each do |element|
  # 遍历每个element并进行处理
end

require 'nokogiri'

doc = Nokogiri::HTML(response.body)
doc.css('selector').each do |element|
  # 遍历每个匹配的元素并进行处理
end
