我如何使用 Nokogiri 和 cURB 进行抓取？
How can I scrape with Nokogiri and cURB?
所以我正在尝试抓取 www.latimes.com 的某个部分作为练习，而我选择的部分 "trb_outfit_group trb_outfit_section" 似乎不会抓取，有什么建议吗？如果需要，我可以 post latimes.com HTML。
这是我的代码：
require'nokogiri'
require'curb'
http = Curl.get("http://www.latimes.com/") do |http|
http.headers['User-Agent'] = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10; rv:33.0) Gecko/20100101 Firefox/33.0"
end
html = Nokogiri::HTML(http.body_str)
html.css("trb_outfit_group trb_outfit_section").each do |node|
puts node.inner_html "\n\n"
end
这是我要抓取的代码：

考虑一下：
require'nokogiri'
require'curb'
url = Curl.get("http://www.latimes.com/") do |http|
http.headers['User-Agent'] = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10; rv:33.0) Gecko/20100101 Firefox/33.0"
end
html = Nokogiri::HTML(url.body_str)
puts html.css(".trb_outfit_group.trb_outfit_section").inner_html
注：
- CSS 类 的选择器是错误的。
- 要获得
inner_html，您不需要遍历节点。
- 将变量
http 重命名为 url，因为它隐藏了迭代器中使用的局部变量。
所以我正在尝试抓取 www.latimes.com 的某个部分作为练习，而我选择的部分 "trb_outfit_group trb_outfit_section" 似乎不会抓取，有什么建议吗？如果需要，我可以 post latimes.com HTML。
这是我的代码：
require'nokogiri'
require'curb'
http = Curl.get("http://www.latimes.com/") do |http|
http.headers['User-Agent'] = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10; rv:33.0) Gecko/20100101 Firefox/33.0"
end
html = Nokogiri::HTML(http.body_str)
html.css("trb_outfit_group trb_outfit_section").each do |node|
puts node.inner_html "\n\n"
end
这是我要抓取的代码：
