Ruby 代码-服务器端获取HTTP网站内容

2006年9月20日星期三

使用Ruby的Network and Web Libraries,能够非常方便的获取一个HTTP网页的内容,如获取优友地带首页的内容:


require ‘net/http’


h = Net::HTTP.new(’www.uuzone.com’, 80)

resp, data = h.get(’/html/friend/’, nil )

puts “Code = #{resp.code}”

puts “Message = #{resp.message}”

resp.each {|key, val| printf “%-14s = %-40.40s\n”, key, val }

p data[0..55]


以上代码片断中的data即为返回的网页内容,关于Ruby 网络应用的详细参考可见《Programming Ruby》中的Network and Web Libraries章节,如果你是在Windows下安装Ruby, 这本书就在Ruby安装目录下:doc/ProgrammingRuby.chm


ZhouRuby扩展还为Ruby扩展了一个HttpRequest类,将Ruby对网络的支持又变得简单易用了很多,非常好用。
