socket.io如何给指定的客户端发送自定义事件?
如题。。另外想问一下哪里有socket.io的教程啊,感觉socket.io官网上的例子太简单,而且有些写法似乎有问题。

缓存每个Client就行了
之前試寫的聊天, 主要是io.sockets.emit(‘updatechat’, socket.username, message);
io.sockets.on ( ‘connection’, function(socket) { // when the client emits ‘sendchat’, this listens and executes socket.on ( ‘sendchat’, function(message) { //socket.broadcast.emit //( // ‘updatechat’, { Content: message } //);
io.sockets.emit('updatechat', socket.username, message);
}
);
// when the client emits 'adduser', this listens and executes
socket.on
(
'adduser', function(username)
{
// we store the username in the socket session for this client
socket.username = username;
// add the client's username to the global list
usernames[username] = username;
// echo to client they've connected
socket.emit('updatechat', 'SERVER', 'you have connected');
// echo globally (all clients) that a person has connected
socket.broadcast.emit('updatechat', 'SERVER', username + ' has connected');
// update the list of users in chat, client-side
io.sockets.emit('updateusers', usernames);
}
);
// when the user disconnects.. perform this
socket.on
(
'disconnect', function()
{
// remove the username from global usernames list
delete usernames[socket.username];
// update list of users in chat, client-side
io.sockets.emit('updateusers', usernames);
// echo globally that this client has left
socket.broadcast.emit('updatechat', 'SERVER', socket.username + ' has disconnected');
}
);
}
);
