在Ruby 1.9.3中设置HTTP超时 [英] Setting an HTTP Timeout in Ruby 1.9.3

问题描述

我正在使用Ruby 1.9.3，需要获取URL.我可以使用Net::HTTP进行此操作，但是，如果站点关闭，则Net::HTTP最终会挂起.

I'm using Ruby 1.9.3 and need to GET a URL. I have this working with Net::HTTP, however, if the site is down, Net::HTTP ends up hanging.

在搜索互联网时，我已经看到许多人都面临着类似的问题，所有问题都带有骇人听闻的解决方案.但是，这些帖子中有很多都是很老的.

While searching the internet, I've seen many people faced similar problems, all with hacky solutions. However, many of those posts are quite old.

要求:

• 我希望使用Net::HTTP来安装新的gem.
• 我需要正文和响应代码. (例如200)
• 我不想require open-uri，因为那样会进行全局更改并引发一些安全问题.
• 我需要在X秒内获取一个URL，否则返回错误.

• I'd prefer using Net::HTTP to installing a new gem.
• I need both the Body and the Response Code. (e.g. 200)
• I do not want to require open-uri, since that makes global changes and raises some security issues.
• I need to GET a URL within X seconds, or return error.

使用Ruby 1.9.3，如何在设置超时时获取URL?

Using Ruby 1.9.3, how can I GET a URL while setting a timeout?

为澄清起见，我现有的代码如下:

To clarify, my existing code looks like:

Net::HTTP.get_response(URI.parse(url))

尝试添加:

Net::HTTP.open_timeout(1000)

结果:

NoMethodError: undefined method `open_timeout' for Net::HTTP:Class

推荐答案

您可以设置

You can set the open_timeout attribute of the Net::HTTP object before making the connection.

uri = URI.parse(url)
Net::HTTP.new(uri.hostname, uri.port) do |http|
  http.open_timeout = 1000
  response = http.request_get(uri.request_uri)
end
