Websockets with Rails(Puma) - WebSocket 握手期间出错:意外响应代码:200 [英] Websockets with Rails(Puma) - Error during WebSocket handshake: Unexpected response code: 200

问题描述

我正在尝试在 Rails4.1 应用程序中使用 websocket

I am trying to use websocket in my Rails4.1 application

以下是一些相关的代码片段:

Here are some relevant code snippets:

宝石文件:

gem 'websocket-rails'
gem 'puma'

development.rb

development.rb

 config.middleware.delete Rack::Lock

我在本地启动服务器:

bundle exec puma -p 3000

在 chrome 控制台中，我看到一个连接错误:

In the chrome console I see a connection error:

new WebSocketRails('localhost:3000/post/hello', true);

WebSocket connection to 'ws://localhost:3000/post/hello' failed: Error during WebSocket handshake: Unexpected response code: 200

任何人都可以帮助我在 Rails 中本地使用 Web 套接字需要做什么吗?

Can anyone help with what I need to do to use web sockets locally in Rails?

初始化程序/eventmachine.rb

initializers/eventmachine.rb

Thread.new { EventMachine.run } unless EventMachine.reactor_running? && EventMachine.reactor_thread.alive

推荐答案

在您的控制台中试试这个:

Try this in your console:

window.dispatcher = new WebSocketRails window.document.location.host + '/websocket'

您可以在 config/events.rb 文件以及用于处理事件的任何控制器中配置您想要执行的其余操作

You configure the rest of what you want to do in the config/events.rb file and whatever controllers you use to handle the events
