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")
