Golang : Pat multiplexer routing example

This is a short tutorial on how to use Pat multiplexer - a Sinatra style pattern muxer for Go's net/http library.

First :

>go get github.com/bmizerany/pat

before running the code below

 package main

 import (
 "fmt"
 "github.com/bmizerany/pat"
 "net/http"
 )

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

 func ReplyNamePat(w http.ResponseWriter, r *http.Request) {
 parameters := r.URL.Query()
 name := parameters.Get(":name")
 w.Write([]byte(fmt.Sprintf("Hello %s !", name)))
 }

 func main() {
 mx := pat.New()
 mx.Get("/", http.HandlerFunc(SayHelloWorld))
 mx.Get("/:name", http.HandlerFunc(ReplyNamePat))

 http.Handle("/", mx)
 http.ListenAndServe(":8080", nil)
 }

Sample output :

http://localhost:8080/Adam

Hello Adam !

http://localhost:8080/

Hello, World!
