在Ruby中,使用“net / http”,我们必须使用“？”自己加入url和查询？

在下面的代码中,我们必须使用url.path和url.query来加入？字符？有更优雅的方式吗？我必须使用net / http,因为在某些情况下,我想把字符串放在用户代理的头中.

require 'net/http'

url_string = 'http://www.time.gov/timezone.cgi?Pacific/d/-8'

url = URI.parse(url_string)

response = Net::HTTP.start(url.host,url.port) do |http|
  http.get(url.path + '?' + url.query)
end
puts response.body[/<td.*(\d\d:\d\d:\d\d)/,1]

解决方法

对URI对象使用request_uri方法：

您的代码更新版本：

require 'net/http'

url_string = 'http://www.time.gov/timezone.cgi?Pacific/d/-8'

url = URI.parse(url_string)

response = Net::HTTP.start(url.host,url.port) do |http|
  http.get(url.request_uri)
end
puts response.body[/<td.*(\d\d:\d\d:\d\d)/,1]
