go web编程-使用Mux控制路由访问

package main

import (
    "io"
    "log"
    "net/http"
)

func main() {
    mux := http.NewServeMux()
    mux.Handle("/", &myHandler{})

    err := http.ListenAndServe(":8080", mux)
    if err != nil {
        log.Fatal(err)
    }
}

type myHandler struct {}

func (*myHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) {
    io.WriteString(w, "hello")
}
