go-http-server

a lightweight http server.

import "github.com/marrbor/go-http-server/server"

Usage

Prepare an endpoint function.

Signature of endpoint function is func xxx(w http.ResponseWriter, r *http.Request). no return values.

e.g.:

func foo(w http.ResponseWriter, r *http.Request) {
	if r.Method != http.MethodGet {
		gohttp.MethodNotAllowed(w, nil)
	}
	if err := gohttp.JSONResponse(w, &a); err != nil {
		gohttp.InternalServerError(w, err)
	}
}

func bar(w http.ResponseWriter, r *http.Request) {
	gohttp.responseOK()
}

Prepare function entry point.

Its type is EntryPoint structure.

e.g.:

var eps = []server.EntryPoint{
	{Resource: "foo", Function: foo},
	{Resource: "bar", Function: bar},
}

Generate server instance and start it.

• Server takes one chan error channel at Start.
• When something wrong to run the server, the server send error to this channel.
• When Stop called, the server also return http: Server closed error.

func main() {
	sigCh := make(chan os.Signal)
	signal.Notify(sigCh, os.Interrupt, os.Kill)
	hs := server.NewServer(8888, eps, nil)

	srvCh := make(chan error)
	hs.Start(srvCh)
LOOP:
    for {
		select {
			case sig := <- sigCh:
                golog.Info(sig)
				hs.Stop() // stop server when signal detect.
			case err := <- srvCh:
                golog.Info(err)
				break LOOP // exit loop when
		}
	}
	os.Exit(0)
}
