Golang : Denco multiplexer example
Kinda free today to test out couple of Golang's web multiplexers. One of the most interesting multiplexers that I've tried is the Denco package. It is pretty straightforward to use and you can get the posted values easily with denco.Params
.
Redirecting to different functions based on URL path patterns can be done easily too with the []denco.Record
type. (see http://godoc.org/github.com/naoina/denco#Record)
This example will focus on the multiplexer section of Denco and it is taken with slight modification from https://github.com/naoina/denco
.
package main
import (
"fmt"
"github.com/naoina/denco"
"net/http"
)
func Home(w http.ResponseWriter, r *http.Request, params denco.Params) {
w.Write([]byte("Hello, World!"))
}
func HelloUser(w http.ResponseWriter, r *http.Request, params denco.Params) {
w.Write([]byte(fmt.Sprintf("Hello, %s!", params.Get("name"))))
}
func main() {
mx := denco.NewMux()
handler, err := mx.Build([]denco.Handler{
mx.GET("/", Home),
mx.GET("/hellouser/:name", HelloUser),
mx.POST("/hellouser/:name", HelloUser),
})
if err != nil {
panic(err)
}
http.ListenAndServe(":8080", handler)
}
Sample output :
http://localhost:8080/hellouser/Adam
