Golang : Muxing with Martini example



Tags : golang http web-router multiplexer martini

In this quick tutorial, we will learn how to do basic multiplexing with Martini package. One thing I really like about Martini package is that you can achieve many common tasks with just one or two lines. Learn more about this package at http://martini.codegangsta.io/. Meanwhile, this is the code example on how to do multiplexing with Martini.

 package main

 import (
 "fmt"
 "github.com/go-martini/martini"
 "net/http"
 )

 func Home(w http.ResponseWriter, r *http.Request) {
 w.Write([]byte("Hello, World!"))
 }

 func SayHello(w http.ResponseWriter, r *http.Request, params martini.Params) {
 w.Write([]byte(fmt.Sprintf("Hello, %s!", params["name"])))
 }

 func main() {

 mx := martini.Classic()
 mx.Get("/", Home)
 mx.Get("/:name", SayHello)

 // martini default port number is 3000
 // example on how to change to 8080
 mx.RunOnAddr(":8080")
 http.Handle("/", mx)
 }

Run the code and point your browser to http://localhost:8080/Jeff

Sample output :

http://localhost:8080

Hello, World!

http://localhost:8080/Jeff

Hello, Jeff!


go run martinimux.go

[martini] listening on :8080 (development)

[martini] Started GET / for [::1]:65494

[martini] Completed 200 OK in 234.235µs

[martini] Started GET /Jeff for [::1]:65494

[martini] Completed 200 OK in 95.226µs
