Question

我正在尝试使用Socket.io v.7中的新“房间”功能来创建动态聊天室，但我在我的示例中遇到静态房间问题。根据用户选择的URL，他们应该在room1或room2中结束。用户在聊天中输入的任何内容都应该广播给同一房间内的用户。我有2个浏览器（chrome＆amp; ff），每个浏览器都有一个打开到/ room1和/ room2的标签，但我输入的任何内容似乎都没有广播到其他标签。我做错了什么？

服务器代码

var app = require('express').createServer();
var io = require("socket.io").listen(app);

io.sockets.on('connection', function (socket) {

    // join to room and save the room name
    socket.on('join room', function (room) {
        socket.set('room', room, function() { console.log('room ' + room + ' saved'); } );
        socket.join(room);
    })

    socket.on('message', function(data) {
        console.log("Client data: " + data);

        // lookup room and broadcast to that room
        socket.get('room', function(err, room) {
            //room example - https://github.com/learnboost/socket.io
            // neither method works for me
            socket.broadcast.to(room).emit('new fan');
            io.sockets.in(room).emit('new non-fan');
        })
    })
});

app.get('/room1', function(req, res){       
    res.render('example2-client.ejs', {layout:false});
});

app.get('/room2', function(req, res){       
    res.render('example2-client-2.ejs', {layout:false});
});

app.listen(4000);

Answer 1

您似乎没有听这些事件

socket.broadcast.to(room).emit('new fan');
io.sockets.in(room).emit('new non-fan');

在您需要的客户端：

socket.on('new fan', function (data) {
    console.log('new fan');
});

您也没有将消息发送给客户。内：

socket.on('message', function(data) { })

在服务器上

，你需要做：

io.sockets.in(room).emit('message', data);
