使用 em-websocket gem 无法将连接更改为"ws://"RUBY



我是Ruby新手。

我正在尝试使用WebSocket连接。所以我用他们的websocket宝石。我也使用瘦网络服务器。我做了榜样告诉我的每一件事。所以请帮帮我。

但服务器一直在回复我:

HTTP/1.1 200 OK
Content-Type: text/html; charset=utf-8
X-UA-Compatible: IE=Edge
ETag: "7592ed842deb971babc6640ff75207fb"
Cache-Control: max-age=0, private, must-revalidate
X-Request-Id: f2d12b00aa2eb202b24c309ce0570da0
X-Runtime: 0.008190
Connection: close
Server: thin 1.5.0 codename Knife

客户请求:

GET /home/webSocket HTTP/1.1
Upgrade: websocket
Connection: Upgrade
Host: localhost:3000
Origin: http://localhost:3000
Pragma: no-cache
Cache-Control: no-cache
Sec-WebSocket-Key: i6Efmjpxmz2GOFpjduxoyA==
Sec-WebSocket-Version: 13
Sec-WebSocket-Extensions: x-webkit-deflate-frame

客户端代码:

$(document).ready(
    function() {
        ws = new WebSocket("ws://localhost:3000/home/webSocket");
        ws.onopen = function() {
          alert('open');
          ws.send("hello server");
        };
        ws.onmessage = function(evt) { alert(evt.data); };
        ws.onclose = function() { alert('close'); };
    });

这是服务器端代码:

def webSocket
    require "rubygems"
    require "em-websocket"
    EventMachine.run {
     EventMachine::WebSocket.start(:host => "0.0.0.0", :port => 8000) do |ws|
     ws.onopen { |handshake|
       puts "WebSocket opened #{{
          :path => handshake.path,
          :query => handshake.query,
          :origin => handshake.origin,
        }}"
        ws.send "Hello Client!"
      }
      ws.onmessage { |msg|
        ws.send "Pong: #{msg}"
      }
      ws.onclose {
        puts "WebSocket closed"
      }
      ws.onerror { |e|
        puts "Error: #{e.message}"
      }
      end
    }
  end

EventMachine正在侦听端口8000:EventMachine::WebSocket.start(:host => "0.0.0.0", :port => 8000),但您正在尝试连接到端口3000:ws = new WebSocket("ws://localhost:3000/home/webSocket");

将其更改为连接到端口8000:

ws = new WebSocket("ws://localhost:8000/home/webSocket");

尽管除非您特别希望将/home/webSocket传递给EventMachine,否则不需要额外的路径。
