A library of Go application, it can make the Go application run like Nginx. Implements the daemon, graceful restart and graceful shutdown.

http.go

package main

import (
        "flag"
        "fmt"
        "github.com/wllenyj/goginx"
        "log"
        "net/http"
        "os"
)

var port = flag.String("p", "8883", "port")

func handler(w http.ResponseWriter, r *http.Request) {
        ret := fmt.Sprintf("pid:%d\n", os.Getpid())
        w.Write([]byte(ret))
}

func main() {
        flag.Parse()
        program, err := goginx.Daemon()
        if err != nil {
                log.Printf("Daemon err. %s", err)
                return
        }
        http.HandleFunc("/hello", handler)

        if err = program.ListenAndServe(":"+*port, nil); err != nil {
                log.Printf("listen err. %s", err)
                return
        }
        program.Run()
}
