如何在Ruby中使用mechanize执行Head请求

Question

我可以HEAD使用Faraday(Faraday.head url)执行请求,但我在当前项目中使用Mechanize.

我想从头(文件名)中获取一个值而不下载文件.Mechanize gem是否提供这样的选项？我正在使用v2.0.

Answer 1

就像get它head反而是:

page = agent.head 'http://www.google.com/'
page.body.length
#=> 0
page.header.keys
#=> ["date", "expires", "cache-control", "content-type", "set-cookie", "p3p", "server", "x-xss-protection", "x-frame-options", "transfer-encoding"]
