ruby - 防止连接到 URL 时超时

Question

我想在下面的代码中使用 Benchmark 查看访问 url 所花费的时间。我也尝试在没有基准测试的情况下做同样的事情。即获取测试开始时间和测试结束时间，将两者相减得到时间。两种方法都以相同的超时错误结束。

require 'open-uri'
require 'benchmark'

response = nil
puts "opening website with benchmark..."
puts Benchmark.measure{
  response = open('http://mywebsite.com')
}

puts "Done !"
status = response.status
puts status

错误:

opening website with benchmark...

当我尝试在我的浏览器中连接到此 URL 时，它始终需要大约 2-3 分钟才能访问。

我搜索了谷歌，但没有找到对我的问题有用的答案。我知道我必须更改某项的超时设置，但无法弄清楚是哪一个。有人可以帮忙吗？

使用 :read_timeout 选项，以秒为单位指定，例如，

open('foo.com', :read_timeout => 10)
