Route Structure about httprouter

[julienschmidt]

Exactly like the example in the README:

package main

import (
    "fmt"
    "github.com/julienschmidt/httprouter"
    "log"
    "net/http"
)

func Index(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
    fmt.Fprint(w, "Welcome!\n")
}

func Title(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
    fmt.Fprintf(w, "The Title is: %s\n", ps.ByName("title"))
}

func main() {
    router := httprouter.New()
    router.GET("/", Index)
    router.GET("/:title", Title)

    log.Fatal(http.ListenAndServe(":8080", router))
}
