要向所有客户发送内容,请使用:
io.sockets.emit('response', data);
要从客户端接收,请使用:
socket.on('cursor', function(data) {
...
});
如何将两者结合起来,以便在从客户端收到服务器上的消息时,我将该消息发送给除发送消息的用户以外的所有用户?
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然后在客户端进行检查或者是否有更简单的方法来破解它?

这是我的列表(已更新为1.0):
// 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');

来自@LearnRPG答案但是1.0:
// send to current request socket client
socket.emit('message', "this is a test");
// sending to all clients, include sender
io.sockets.emit('message', "this is a test"); //still works
//or
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
// docs says "simply use to or in when broadcasting or emitting"
io.in('game').emit('message', 'cool game');
// sending to individual socketid, socketid is like a room
socket.broadcast.to(socketid).emit('message', 'for your eyes only');
要回答@Crashalot的评论,socketid

以下是关于从0.9.x更改为1.x的更完整答案。
// 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

broadcast.emit将msg发送给所有其他客户端(发件人除外)
socket.on('cursor', function(data) {
socket.broadcast.emit('msg', data);

对于房间内的名称空间,循环房间中的客户列表(类似于Nav的答案)是我发现的两种方法之一。另一种是使用排除。 E.G。
socket.on('message',function(data) {
io.of( 'namespace' ).in( data.roomID ).except( socket.id ).emit('message',data);
}

io.on('connect', onConnect);
function onConnect(socket){
// sending to the client
socket.emit('hello', 'can you hear me?', 1, 2, 'abc');
// sending to all clients except sender
socket.broadcast.emit('broadcast', 'hello friends!');
// sending to all clients in 'game' room except sender
socket.to('game').emit('nice game', "let's play a game");
// sending to all clients in 'game1' and/or in 'game2' room, except sender
socket.to('game1').to('game2').emit('nice game', "let's play a game (too)");
// sending to all clients in 'game' room, including sender
io.in('game').emit('big-announcement', 'the game will start soon');
// sending to all clients in namespace 'myNamespace', including sender
io.of('myNamespace').emit('bigger-announcement', 'the tournament will start soon');
// sending to individual socketid (private message)
socket.to(<socketid>).emit('hey', 'I just met you');
// sending with acknowledgement
socket.emit('question', 'do you think so?', function (answer) {});
// sending without compression
socket.compress(false).emit('uncompressed', "that's rough");
// sending a message that might be dropped if the client is not ready to receive messages
socket.volatile.emit('maybe', 'do you really need it?');
// sending to all clients on this node (when using multiple nodes)
io.local.emit('hi', 'my lovely babies');

更新了列表以获取更多文档。
socket.emit('message', "this is a test"); //sending to sender-client only
socket.broadcast.emit('message', "this is a test"); //sending to all clients except sender
socket.broadcast.to('game').emit('message', 'nice game'); //sending to all clients in 'game' room(channel) except sender
socket.to('game').emit('message', 'enjoy the game'); //sending to sender client, only if they are in 'game' room(channel)
socket.broadcast.to(socketid).emit('message', 'for your eyes only'); //sending to individual socketid
io.emit('message', "this is a test"); //sending to all clients, include sender
io.in('game').emit('message', 'cool game'); //sending to all clients in 'game' room(channel), include sender
io.of('myNamespace').emit('message', 'gg'); //sending to all clients in namespace 'myNamespace', include sender
socket.emit(); //send to all connected clients
socket.broadcast.emit(); //send to all connected clients except the one that sent the message
socket.on(); //event listener, can be called on client to execute on server
io.sockets.socket(); //for emiting to specific clients
io.sockets.emit(); //send to all connected clients (same as socket.emit)
io.sockets.on() ; //initial connection from a client.

使用此编码
io.sockets.on('connection', function (socket) {
socket.on('mousemove', function (data) {
socket.broadcast.emit('moving', data);
});
这个socket.broadcast.emit()将在函数中发出everthing,除了发出的服务器
