http模拟登录

= =其实很简单，写这个的目的呢，是为了练习下Ruby而已

就是post到登录地址，得到cookie，然后以后的请求都用这个cookie就好了。

 require 'net/http'
 module EasyHTTP
     class HTTP
         def initialize(url)
             @url = url
             @cookie = nil
         end
         def login
             uri =  URI.parse(@url)
             params = {}
             params['user.username'] = '1111@xx.com'
             params['user.password'] = 'xxxx'
             res = Net::HTTP.post_form(uri , params)
             @cookie = res.header['set-cookie'].split('; ')[0]
         end
         def get(url)
             login unless @cookie
             uri = URI.parse(url)
             http = Net::HTTP.new(uri.host , uri.port)
             request = Net::HTTP::Get.new(uri.path)
             request['Cookie'] = @cookie
             res = http.request(request)
             res.body
         end
     end
 end

 sample = EasyHTTP::HTTP.new("http://loginAction url")
 puts sample.get("http://some url u want")
