package main

import (
    "net/http"

    "github.com/zenazn/goji"
    "github.com/zenazn/goji/web"
)

func main() {
    mux1 := web.New()
    mux1.Get("/", func(w http.ResponseWriter, r *http.Request) {
        w.Write([]byte("domain one mux\n"))
    })
    http.Handle("domainone.com/", mux1)

    mux2 := web.New()
    mux2.Get("/", func(w http.ResponseWriter, r *http.Request) {
        w.Write([]byte("domain two mux\n"))
    })
    http.Handle("domaintwo.com/", mux2)

    goji.Get("/", func(w http.ResponseWriter, r *http.Request) {
        w.Write([]byte("main mux\n"))
    })
    goji.Serve()
}

测试:
