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?

其他情况下

io.of('/chat').on('connection', function (socket) {
    //sending to all clients in 'room' and you
    io.of('/chat').in('room').emit('message', "data");
};

其他情况下

io.of('/chat').on('connection', function (socket) {
    //sending to all clients in 'room' and you
    io.of('/chat').in('room').emit('message', "data");
};

对于房间中的命名空间,循环房间中的客户端列表(类似于Nav的回答)是我发现的两种可行的方法之一。另一种是使用排除。如

socket.on('message',function(data) {
    io.of( 'namespace' ).in( data.roomID ).except( socket.id ).emit('message',data);
}

我正在使用名称空间和房间-我发现

socket.broadcast.to('room1').emit('event', 'hi');

在哪里工作

namespace.broadcast.to('room1').emit('event', 'hi');

没有

这里是一个更完整的答案,关于从0.9改变了什么。X到1.x。

 // send to current request socket client
 socket.emit('message', "this is a test");// Hasn't changed

 // sending to all clients, include sender
 io.sockets.emit('message', "this is a test"); // Old way, still compatible
 io.emit('message', 'this is a test');// New way, works only in 1.x

 // sending to all clients except sender
 socket.broadcast.emit('message', "this is a test");// Hasn't changed

 // sending to all clients in 'game' room(channel) except sender
 socket.broadcast.to('game').emit('message', 'nice game');// Hasn't changed

 // sending to all clients in 'game' room(channel), include sender
 io.sockets.in('game').emit('message', 'cool game');// Old way, DOES NOT WORK ANYMORE
 io.in('game').emit('message', 'cool game');// New way
 io.to('game').emit('message', 'cool game');// New way, "in" or "to" are the exact same: "And then simply use to or in (they are the same) when broadcasting or emitting:" from http://socket.io/docs/rooms-and-namespaces/

 // sending to individual socketid, socketid is like a room
 io.sockets.socket(socketid).emit('message', 'for your eyes only');// Old way, DOES NOT WORK ANYMORE
 socket.broadcast.to(socketid).emit('message', 'for your eyes only');// New way

广播。Emit将MSG发送到所有其他客户端(发送方除外)

socket.on('cursor', function(data) {
  socket.broadcast.emit('msg', data);
});
