Ruby 2.3-向net:http请求添加超时错误和通知

我有一个可以产生错误并将其发送给Active Admin使用的系统.

I have a working system to produce errors and send them to be used by Active Admin.

例如在Active admin中，对于我们CMS的特定页面，该页面可能会执行:

For example in Active admin, for a specific page of our CMS, the page might execute :

url_must_be_accessible("http://www.exmaple.com", field_url_partner, "URL for the partner")

这将使用下面的代码向Active Admin编辑器发送不同类型的错误通知:

And this uses the code below to send to the Active Admin Editor different type of errors notifications:

module UrlHttpResponseHelper

  def url_must_be_accessible(url, target_field, field_name)      
    if url
      url_response_code = get_url_http_response(url).code.to_i
      case url_response_code
      when -1                                                         
        # DNS issue; website does not exist; 
        errors.add(target_field,
          "#{field_name}: DNS Problem -> #{url} website does not exist")
      when 200
        return 
      when 304
         return
      else
        errors.add(target_field,
          "#{field_name}: #{url} sends #{url_response_code} response code")
      end
    end
  end

  def get_url_http_response(url)  
    uri = URI.parse(URI.encode(url))
    request = Net::HTTP.get_response(uri)
    return request
  rescue Errno::ECONNREFUSED, SocketError => e
    OpenStruct.new(code: -1)
  end

end

在本地模式下，效果很好！但是在生产中，我们使用的是Heroku，当请求pn Heroku的时间超过30秒时，例如您尝试使用此链接" http ://www.exmaple.com "，则该应用程序崩溃，并显示.

In local mode, this worked great! But in production, we're on Heroku and when a request pn Heroku goes beyond 30 seconds like if you try on this link "http://www.exmaple.com", the app crashes with a "H12 error".

我想在代码上添加两件事 -超时:我想我既需要read_timeout也需要open_timeout，并且read_timeout + open_timeout应该小于<.到30秒，让我们采取一些安全措施，更好< 25秒

I'd like to add to the code above two things - timeouts: i think i need both read_timeout and open_timeout and that the read_timeout + open_timeout should be < to 30 seconds, with let's take some security , better < 25seconds

• 如果请求在25秒后仍然执行"，则通过放弃/放弃请求

，并通过向用户发送通知来捕获此我们故意删除请求，因为存在超时风险".我想将当前系统与以下方式配合使用:

and catch this "we dropped the request intentionnally because risk of timeout" by sending a notification to the user. I'd like to use my current system with somehting along the lines of:

 rescue Errno::ECONNREFUSED, SocketError => e
    OpenStruct.new(code: -7) # = some random number
  end

case url_response_code
when -7
  errors.add(target_field,
          "#{field_name}: We tried to reach #{url} but this takes too long and risks crashing the app. please check the url and try again.")

我该如何创建类似-1的代码，但又如何创建一个代码以挽救我自己执行的此超时"/放弃请求尝试".

How can I create a code like -1 but another one to rescue this "timeout"/"drop the request attempt" that I myself enforce.

尝试过，但无济于事.如果到达25秒，我将无法创建用于捕获和删除此请求的代码...

Tried but nothing works. I don't manage to create the code for catch and drop this request if reaches 25 seconds...
