如何在Ruby中使用机械化执行Head请求 [英] How can I perform a Head request using mechanize in Ruby

问题描述

我可以使用Faraday(Faraday.head网址)执行HEAD请求，但是我正在当前项目中使用Mechanize.

I can perform a HEAD request with Faraday (Faraday.head url), but I am using Mechanize on my current project.

我想从标题(文件名)中获取一个值而不下载文件.机械化宝石是否提供了这样的选择?我正在使用v2.0.

I would like to grab a value from the header (filename) without downloading the file. Does the Mechanize gem provide such an option? I am using v2.0.

推荐答案

就像get一样，但它是head:

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"]
