close 似乎不适用于 WebSocket [英] close does not seem to work with WebSocket

问题描述

我有这个简单的 javascript 代码:

I have this simple javascript code :

window.ws = new WebSocket('ws://127.0.0.1:8000/');

ws.onopen = function() { 
  ws.send('hello');
}

还有一个像这样的 Ruby 服务器:

And a server in Ruby like this :

require 'em-websocket'

class Websocket
  def run
    EventMachine.run do

      EM::WebSocket.start(host: '0.0.0.0', port: '8000') do |ws|
        ws.onopen do |handshake|
          puts "Connected"
        end

        ws.onclose do
          puts "Closed"
        end

        ws.onmessage do |msg|
          p msg
        end
      end
    end
  end
end

当连接关闭时，服务器应该打印Closed".在浏览器中，当我执行 window.ws.close() 时，服务器没有收到任何信息，但是当我重新加载页面时，它会打印消息.

When a connection is close, the server should print "Closed". In the browser, when I do window.ws.close(), nothing is received by the server, but when I reload the page, it print the message.

有没有办法强制客户端说连接已关闭?

Is there a way to force the client to say than the connection is closed?
