Goサンプル的なライブラリ 追加

https://github.com/iwot/go-util

Goサンプル的なライブラリにHttpRouterを追加しました。
使用例を https://github.com/iwot/go-util/tree/master/example/httprouter に置いてます。

package main

import (
  "./app/articles"
  "fmt"
  "github.com/iwot/go-util/util"
  "html"
  "net/http"
  "os"
)

func main() {

    basePath := "/articles/"
    router := util.NewHttpRouter().SetBasePath(basePath)
    router.SetRoute("", articles.TopPage)
    router.SetRoute("article/<id>", articles.ArticlePage)

    // for default error
    router.SetError("default", func(message string, w http.ResponseWriter, r *http.Request) {
        fmt.Fprintf(w, "Error, %q\n", html.EscapeString(message))
    })
    // for 404 error
    router.SetError("404", func(message string, w http.ResponseWriter, r *http.Request) {
        fmt.Fprintf(w, "404 Error, %q\n", html.EscapeString(message))
    })
    // for other error
    router.SetError("other", func(message string, w http.ResponseWriter, r *http.Request) {
        fmt.Fprintf(w, "other Error, %q\n", html.EscapeString(message))
    })

    http.Handle(basePath, router)
    fmt.Fprint(os.Stdout, "http://localhost:8000/articles/\n")
    fmt.Fprint(os.Stdout, "http://localhost:8000/articles/article/1\n")
    err := http.ListenAndServe("localhost:8000", nil)
    if err != nil {
        panic(err)
    }
}
