我發現這個例子https://play.golang.org/p/zyZJKGFfyT保持與GO聽TCP服務器的最佳方式是什麼?
package main
import (
"fmt"
"net"
"os"
)
// echo "Hello server" | nc localhost 5555
const (
CONN_HOST = "localhost"
CONN_PORT = "5555"
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.
reqLen, err := conn.Read(buf)
reqLen = reqLen
if err != nil {
fmt.Println("Error reading:", err.Error())
}
// Send a response back to person contacting us.
conn.Write([]byte("hello"))
conn.Close()
}
回聲 「測試」 | nc 127.0.0.1 5555
在生產中監聽GO服務器的最佳方式是什麼? 在本地主機工作正常,但生產
