My problem is, I have to limit the maximum active connections count at any particular time to 20.

推荐答案

您可以使用

You can use the netutil.LimitListener function to wrap around net.Listener if you don't want to implement your own wrapper:-

connectionCount := 20

l, err := net.Listen("tcp", ":8000")

if err != nil {
    log.Fatalf("Listen: %v", err)
}

defer l.Close()

l = netutil.LimitListener(l, connectionCount)

log.Fatal(http.Serve(l, nil))
