Question

我在从本地rethinkdb服务器获取套接字以将数据流传输到客户端时遇到问题。我对sockets.io相当新，所以我不确定我做错了什么。有人可以看看我的代码并帮助我吗？感谢

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var r = require('rethinkdb');

app.get('/', function(req, res){
  res.sendFile(__dirname + '/index.html');
});

r.connect({ db: "test" }).then(function(conn) {
    r.table('Articles').getField('title').run(conn)
    .then(function(cursor) {
            cursor.each(function(err, item) {
                console.log(item);
            io.sockets.emit("title", item);
        })
    })
})

http.listen(3000, function(){
  console.log('listening on *:3000');
});

            $('#content').append($('<p>').text(data));
