我有一个非常简单的socket.io聊天例如,服务器端代码是这样的:如何从ws客户端连接到socket.io?
https://github.com/js-demos/socketio-chat-demo/blob/master/index.js
var express = require('express');
var app = express();
var http = require('http').Server(app);
var io = require('socket.io')(http);
app.use(express.static('public'));
io.on('connection', function(socket){
socket.on('chat message', function(msg){
io.emit('chat message', msg);
});
});
http.listen(3000, function(){
console.log('listening on *:3000');
});
通过io代码插座连接它的客户端和运作良好:
https://github.com/js-demos/socketio-chat-demo/blob/master/public%2Findex.html
<script>
var socket = io();
$('form').submit(function(){
socket.emit('chat message', $('#m').val());
$('#m').val('');
return false;
});
socket.on('chat message', function(msg){
$('#messages').append($('<li>').text(msg));
});
</script>
但我想使用一些其他的WebSocket客户端连接ŧ他的服务器,说,wscat
:
npm install -g wscat
wscat ws://localhost:3000
但它无法连接,与此错误:
error: Error: socket hang up
我的网址ws://localhost:3000
是错的?如何使它工作?
PS:你可以看到这个项目https://github.com/js-demos/socketio-chat-demo/和尝试
