如何从Ruby的Net :: HTTP中的读取超时错误中判断连接超时错误

Question

我的问题与如何解决超时问题(Ruby,Rails)有关.

以下是从超时中解救的常用方法:

def action
  # Post using Net::HTTP
rescue Timeout::Error => e
  # Do something
end

我想确定在尝试连接到主机时是否引发了异常,或者是否在尝试从主机读取时引发了异常.这可能吗？

这是解决方案(在Ben的修复之后):

require "net/http"
http = Net::HTTP.new("example.com")
http.open_timeout = 2
http.read_timeout = 3
begin
  http.start
  begin
    http.request_get("/whatever?") do |res|
      res.read_body
    end
  rescue Timeout::Error
    puts "Timeout due to reading"
  end
rescue Timeout::Error
  puts "Timeout due to connecting"
end
