Question

我从中获取代码，因为我需要获得美国代理和良好用户代理的内容。

How to GET a URL with User-Agent and timeout through some Proxy in Ruby?

require 'rubygems'
require 'nokogiri'
require 'open-uri'

    user_agent = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_0) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.854.0 Safari/535.2"

    url = "google.com"

    @doc = Nokogiri::HTML(open(url, 'User-Agent' => user_agent, 'read_timeout' => 10 ), nil, "UTF-8")

但我收到了错误：
