Socket.io上的404连接 [英] 404 on Socket.io connect

问题描述

我使用了socket.io网站示例中的代码，但遇到了一些问题

i use code from examples of socket.io site and has some problem

我的服务器代码(在debian 192.168.5.200上)

My server code (on debian 192.168.5.200)

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

server.listen(1337);

app.get('/', function (req, res) {
  res.sendfile(__dirname + '/index.html');
});

io.sockets.on('connection', function (socket) {
  socket.emit('news', { hello: 'world' });
  socket.on('my other event', function (data) {
    console.log(data);
  });
});

我的客户代码(index.html)

My client code (index.html)

<script src="http://{host ip}:1337/socket.io/socket.io.js"></script>
<script>
  var socket = io.connect('http://{host ip}:1337');
  socket.on('news', function (data) {
    console.log(data);
    socket.emit('my other event', { my: 'data' });
  });
</script>

我启动节点服务器 在浏览器中打开http://{host ip}:1337 然后...在Socket.io连接上得到404

i start node server open in browser http://{host ip}:1337 and... got 404 on socket.io connection

它尝试获取"/api/1/?t=..."URL并通过表示无法获取/api/1/?t = ..."且出现404错误得到答案

it try to get "/api/1/?t=..." url and got answer by express "Cannot get /api/1/?t=..." with 404 error

请帮助我(

推荐答案

尝试将您的客户端代码更改为:

Try to change your client code to:

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

此外，为了能够转到/api/1...，您需要注册相应的app.get，例如如app.get("/api/*", ...，它将处理与/api/...的所有连接.否则，预计会收到404错误.

Also, in order to be able to go to /api/1... you need to register the corresponding app.get, e.g. as app.get("/api/*", ..., which would handle all the connections to /api/.... Otherwise it is expected that you will be getting the 404 error.
