Rails获取curl (JSON)请求的响应时间

Question

在我的应用程序中，我是否像这样向外部服务器发送多个请求:

    req = Curl::Easy.new do |curl| 
        curl.url = "https://www.mysite.com"
        curl.headers['Content-type'] = 'application/json'
    end
    req.perform

是否可以检索响应时间(请求需要多长时间)?

一个解决方案，我认为是工作是以下(伪代码)，但有更优雅的东西?

    req = Curl::Easy.new do |curl| 
        curl.url = "https://www.mysite.com"
        curl.headers['Content-type'] = 'application/json'
    end
    timeBefore = Time.now
    req.perform
    timeAfter = Time.now
    responseTime = timeAfter - timeBefore

Answer 1

你可以这样使用Ruby的基准测试模块:

time = Benchmark.realtime do
      req.perform
end
puts "Time elapsed #{time*1000} milliseconds"
