要向所有客户端发送内容,您可以使用:
io.sockets.emit('response', data);
要接收来自客户的信息,您可以使用:
socket.on('cursor', function(data) {
...
});
如何将这两者结合起来,以便在服务器上从客户端接收消息时,将该消息发送给除发送消息的用户之外的所有用户?
socket.on('cursor', function(data) {
io.sockets.emit('response', data);
});
我是否必须通过发送带有消息的client-id,然后在客户端检查来破解它,或者有更简单的方法吗?
以下是我的列表(1.0版本更新):
// sending to sender-client only
socket.emit('message', "this is a test");
// sending to all clients, include sender
io.emit('message', "this is a test");
// sending to all clients except sender
socket.broadcast.emit('message', "this is a test");
// sending to all clients in 'game' room(channel) except sender
socket.broadcast.to('game').emit('message', 'nice game');
// sending to all clients in 'game' room(channel), include sender
io.in('game').emit('message', 'cool game');
// sending to sender client, only if they are in 'game' room(channel)
socket.to('game').emit('message', 'enjoy the game');
// sending to all clients in namespace 'myNamespace', include sender
io.of('myNamespace').emit('message', 'gg');
// sending to individual socketid
socket.broadcast.to(socketid).emit('message', 'for your eyes only');
// list socketid
for (var socketid in io.sockets.sockets) {}
OR
Object.keys(io.sockets.sockets).forEach((socketid) => {});
