Usually, we only put the data we want to send as websocket.send() method's parameter, but I want to know whether there are other parameters like IP that we can put inside the brackets. Can we use it this way:
websocket.send(ip, data); // send data to this ip address
Or I should call other methods?
As I understand it, you want the server be able to send messages through from client 1 to client 2. You cannot directly connect two clients because one of the two ends of a WebSocket connection needs to be a server.
This is some pseudocodish JavaScript:
Client:
var websocket = new WebSocket(server address);
websocket.onmessage = function(str) {
console.log(Someone sent: , str);
};
// Tell the server this is client 1 (swap for client 2 of course)
websocket.send(JSON.stringify({
id: client1
}));
// Tell the server we want to send something to the other client
websocket.send(JSON.stringify({
to: client2,
data: foo
}));
Server:
var clients = {};
server.on(data, function(client, str) {
var obj = JSON.parse(str);
if(id in obj) {
// New client, add it to the id/client object
clients[obj.id] = client;
} else {
// Send data to the client requested
clients[obj.to].send(obj.data);
}
});
