Socket.io和Express3 - 404客户端请求/socket.io/socket.io.js

标签: node.js express websocket socket.io

我尝试从我的Node服务器解析'/socket.io/socket.io.js'时收到404。我无法确定原因。

我的服务器配置如下所示:

 var express = require('express')
  , engine = require('ejs-locals')
  , app = express()
  , http = require('http')
  , server = http.createServer(app)
  , io = require('socket.io').listen(server);


// use ejs-locals for all ejs templates:
app.engine('ejs', engine);

app.set('views',__dirname + '/views');
app.set('view engine', 'ejs'); // so you can render('index')
app.use(express.static(__dirname + '/public'));

//define routes
...

app.listen(3000);



//socket io
io.sockets.on('connection', function (socket) {
  socket.on('set nickname', function (name) {
    socket.set('nickname', name, function () {
      socket.emit('ready');
    });
  });

  socket.on('msg', function () {
    socket.get('nickname', function (err, name) {
      console.log('Chat message by ', name);
    });
  });
});  

在客户端,我有这个:

<script src="/socket.io/socket.io.js"></script>
<script>
  var socket = io.connect('http://localhost:3000');
  socket.on('news', function (data) {
    console.log(data);
    socket.emit('my other event', { my: 'data' });
  });
</script>

我正在本地测试(端口:3000)。套接字代码基本上是从socket.io示例中删除,以使某些工作正常。我已经查看了其他帖子,似乎无法找到我出错的地方。有人可以帮忙吗?

知道了!

HTTP服务器需要在端口上列出(在这种情况下为3000)。然后我删除了app.listen(3000),因为地址已经在使用中并且不需要。

谢谢!
