为什么我无法连接到websocket？ [英] Why did I failed to connect to websocket?

问题描述

具有 ws 模块的节点服务器的代码：

The code of Node server with ws module:

show = console.log

WS = require('ws').Server
wss = new WS port: 8080
wss.on 'connection', (ws) ->
  show 'a connection'
  ws.on 'message', (message) ->
    show 'received: %s', message
  ws.send 'something'

我可以通过在同一台服务器
上运行以下代码来连接到websocket，它发出连接 ：

I can connect to websocket by running the code below on the same server, and it gives out "a connection":

WS = require 'ws'
ws = new WS 'ws://localhost:8080'

但是当我从浏览器运行以下代码行时，没有任何休息：

But when I run these lines of code from browser, there's no respose:

s = new WebSocket('ws://184.82.253.196:8080');
s.send('nothing');

出什么问题了，我该如何解决？

What's problem, how can I fix it?

推荐答案

Websocket服务器默认开始仅监听 127.0.0.1 。使用此代码开始监听所有接口。

Websocket server start listening only 127.0.0.1 by default. Use this code to start listen all interfaces.

show = console.log

WS = require('ws').Server
wss = new WS port: 8080, host: '0.0.0.0'
wss.on 'connection', (ws) ->
  show 'a connection'
  ws.on 'message', (message) ->
    show 'received: %s', message
  ws.send 'something'
