goproxy で basic auth

goproxy に basic auth が付属してて、それを使うだけ

package main

import (
    "flag"
    "github.com/elazarl/goproxy"
    "github.com/elazarl/goproxy/ext/auth"
    "log"
    "net/http"
)

var portNumber = flag.String("port", "9090", "port number.")
var basicAuthUser = flag.String("user", "", "basic auth user name")
var basicAuthPass = flag.String("pass", "", "basic auth user pass")

func main() {
    flag.Parse()
    proxy := goproxy.NewProxyHttpServer()
    proxy.Verbose = true
    if *basicAuthUser != "" && *basicAuthPass != "" {
        log.Println("auth basic")
        auth.ProxyBasic(proxy, "RELM", func(user, pass string) bool {
            log.Println("auth basic do")
            return user == *basicAuthUser && pass == *basicAuthPass
        })
    }

    log.Println("listen:" + *portNumber)
    log.Fatal(http.ListenAndServe(":"+*portNumber, proxy))
}
