Question

我用以下代码来管理吉大港山区的申请,但第二项请求(req2)总是回退。

我在这里没有明显的东西?

request_options = {
  :body => " ",
  :keepalive => true,
  :head => {
     content-type  =>  application/json ,
     accept  =>  application/json ,
     Accept-Encoding  =>  gzip,deflate,sdch 
  }
}

EM.run do
  request_options[:path] =  /default/path 

  conn = EM::HttpRequest.new  https://www.example.com 

  req1 = conn.post request_options
  req1.errback { p  Uh, oh ; EM.stop }
  req1.callback do
    doc = JSON.parse req1.response

    # do stuff with doc

    request_options[:body] =  post-data 
    request_options[:path] =  /new/path 

    req2 = conn.post request_options
    req2.errback { p  Uh, oh ; EM.stop }
    req2.callback do
       puts req2.response
       EM.stop
    end
  end
end

我通过使用<>中程>-Synchrony解决了我的问题。

gem install em-synchrony

随着这一轮椅的安装,我可以按照我的期望使用以下代码来使该守则发挥作用。

request_options = {
  :body => " ",
  :keepalive => true,
  :head => {
     content-type  =>  application/json ,
     accept  =>  application/json ,
     Accept-Encoding  =>  gzip,deflate,sdch 
  }
}

EM.synchrony do
  request_options[:path] =  /default/path 

  conn = EM::HttpRequest.new  https://www.example.com 

  req1 = conn.post request_options
  doc = JSON.parse req1.response

  # do stuff with doc

  request_options[:body] =  post-data 
  request_options[:path] =  /new/path 

  req2 = conn.post request_options
  puts req2.response

  EM.stop
end

我猜想一下,我只是混淆了他们走的路。运行确实是非同步要求,也是零。

你可以在回击中使用同样的电击标。

确保创建新的<条码>。 EM:HttpRequest.new https://www.example.com。
