这是我与所选用户进行私聊的代码。它不会像私人消息一样向所选用户发送消息。
服务器端:
var fs = require('fs'),
http = require('http'),
sio = require('socket.io');
var server = http.createServer( function(req, res) {
if (req.url === '/index') {
fs.readFile('./index.html', function(err, page) {
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(page);
res.end();
});
}
else if (req.url === '/karthick') {
fs.readFile('./karthick.html', function(err, page) {
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(page);
res.end();
});
}
else if (req.url === '/raj') {
fs.readFile('./raj.html', function(err, page) {
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(page);
res.end();
});
}
else if (req.url === '/Harendra') {
fs.readFile('./Harendra.html', function(err, page) {
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(page);
res.end();
});
}
else if (req.url === '/send') {
fs.readFile('./sendingmsg.html', function(err, page) {
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(page);
res.end();
});
}
else {
res.writeHead(301,
{Location: '/index'}
);
res.end();
}
});
server.listen(8000, function() {
console.log('Server listening at http://192.168.1.16/8000');
});
io = sio.listen(server);
// store messages
var messages = [];
io.sockets.on('connection', function(socket){
socket.on('chat message', function(msg){
console.log('Received: ', msg);
messages.push(msg);
io.sockets.emit('chat message', msg);
});
messages.forEach(function(msg) {
socket.send(msg);
})
});
客户端:发送

$('#m').val('');
return false;
});
socket.on('disconnect', function() {
$('#messages').append('<li>Disconnected</li>');
});
</script>

收到客户:1

当我选择用户发送私信时,它无效。请帮帮我一个人
答案 0 :(得分:1)
您在服务器套接字实现中缺少一些逻辑。
不应将邮件发送给io.sockets.emit(...)
的所有客户,而应将其发送到特定的会议室 - socket.to(...).emit(...)
这是抽象逻辑:
你的插座应该属于某个房间,以便接收&#34;私人&#34;消息(socket.join(...)
)
socket.join('roomName');
你应该播放你的私人&#34;发送到特定房间的消息,而不是将消息广播给所有客户。您可以指定房间(socket.to(...)
):
socket.to('roomName').emit('chat message', msg);
