Question

我无法发送＆＃34;嗨＆＃34;从客户端到服务器的消息。有套接字连接，我在客户端建立连接时收到一条消息。但是当我尝试将消息发送回服务器时，它无法正常工作。

我尝试过Android和HTML。所以我很确定它的服务器。

NODE

var socket = require('socket.io');
var io;
module.exports = {
    initialize: function(server) {
        io = socket.listen(server);
        io.on('connection', function(socket) {
            socket.emit('message');
            console.log('connected to socket');
        });
        io.on('hi', function(message) {
            console.log(message);
        });
    }
}

HTML

        script(type"text/javascript").
            var socket = io.connect('http://localhost:3000')

            socket.on('message', function(data){
                console.log('receive message from server on webpage');
            });
    body
        div.container

    footer
        script(type"text/javascript").
            $('#hiButton').click(function(){
                socket.emit('hi', 'send hi to server from webpage');
            });
