GO语言-http包初略使用（ServeMux和pprof）

package main

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

func main() {
    mux := http.NewServeMux()
    mux.HandleFunc("/a", func(w http.ResponseWriter, r *http.Request) {
        io.WriteString(w, "aaaaaa")
    })
    mux.HandleFunc("/b", func(w http.ResponseWriter, r *http.Request) {
        io.WriteString(w, "bbbb")
    })

    mux.HandleFunc("/debug/pprof/", pprof.Index)
    mux.HandleFunc("/debug/pprof/cmdline", pprof.Cmdline)
    mux.HandleFunc("/debug/pprof/profile", pprof.Profile)
    mux.HandleFunc("/debug/pprof/symbol", pprof.Symbol)
    mux.HandleFunc("/debug/pprof/trace", pprof.Trace)

    mux.HandleFunc("/hi", sayhello)

    http.ListenAndServe(":8080", mux)
}

func sayhello(w http.ResponseWriter, r *http.Request) {
    io.WriteString(w, "hi,vijay!!")
}
