Hey there… Where can I find a muti-threaded TCP server example? I searched on the net but I only found basics example with only one client…
[EDIT]
I found the following code, but when I connect 2 or more clients, when some client send some string, server broadcasts this received message to everyone. How can I do to not broadcasting and reply only the client who sent that message? Below the code I found;
go servers are multi client. i guess you need to know who sent a request to properly respond it.
maybe this example help:
package main
import (
"fmt"
"net"
"os"
)
const (
CONN_HOST = ""
CONN_PORT = "3333"
CONN_TYPE = "tcp"
)
func main() {
// Listen for incoming connections.
l, err := net.Listen(CONN_TYPE, CONN_HOST+":"+CONN_PORT)
if err != nil {
fmt.Println("Error listening:", err.Error())
os.Exit(1)
}
// Close the listener when the application closes.
defer l.Close()
fmt.Println("Listening on " + CONN_HOST + ":" + CONN_PORT)
for {
// Listen for an incoming connection.
conn, err := l.Accept()
if err != nil {
fmt.Println("Error accepting: ", err.Error())
os.Exit(1)
}
// Handle connections in a new goroutine.
go handleRequest(conn)
}
}
// Handles incoming requests.
func handleRequest(conn net.Conn) {
// Make a buffer to hold incoming data.
buf := make([]byte, 1024)
// Read the incoming connection into the buffer.
_, err := conn.Read(buf)
if err != nil {
fmt.Println("Error reading:", err.Error())
}
fmt.Println(conn.RemoteAddr())
// Send a response back to person contacting us.
conn.Write([]byte("Message received."))
// Close the connection when you're done with it.
conn.Close()
}
