## demo
```
package main
import (
"fmt"
"log"
"net/http"
"github.com/julienschmidt/httprouter"
)
func Index(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
fmt.Fprint(w, "Welcome!\n")
}
func Hello(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
fmt.Fprintf(w, "hello, %s!\n", ps.ByName("name"))
}
func getuser(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
uid := ps.ByName("uid")
fmt.Fprintf(w, "you are get user %s", uid)
}
func modifyuser(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
uid := ps.ByName("uid")
fmt.Fprintf(w, "you are modify user %s", uid)
}
func deleteuser(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
uid := ps.ByName("uid")
fmt.Fprintf(w, "you are delete user %s", uid)
}
func adduser(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
// uid := r.FormValue("uid")
uid := ps.ByName("uid")
fmt.Fprintf(w, "you are add user %s", uid)
}
func main() {
router := httprouter.New()
router.GET("/", Index)
router.GET("/hello/:name", Hello)
router.GET("/user/:uid", getuser)
router.POST("/adduser/:uid", adduser)
router.DELETE("/deluser/:uid", deleteuser)
router.PUT("/moduser/:uid", modifyuser)
log.Fatal(http.ListenAndServe(":8080", router))
}
