Go 语言net/http 包使用模式：监听多端口等等

func handler2(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hello, HTTP Server1")
}

func handler1(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hello, HTTP Server2")
}
func main() {
go func(){
mux := http.NewServeMux()
mux.HandleFunc("/", handler2)
http.ListenAndServe(":1234", mux)
}()
mux := http.NewServeMux()
mux.HandleFunc("/", handler1)
http.ListenAndServe(":12345", mux)
}
