Golang : HTTP Routing with Goji example
Alright, this tutorial will show you how to do HTTP routing with Carl Jackson a.k.a zenazn's Goji package. Pretty simple to use, but still require some digging to find the parameters from the web's context object.
Without much further ado ...
package main
import (
"flag"
"fmt"
"github.com/zenazn/goji"
"github.com/zenazn/goji/web"
"net/http"
)
func Home(w http.ResponseWriter, r *http.Request) {
w.Write([]byte("Hello, World!"))
}
func SayHello(c web.C, w http.ResponseWriter, r *http.Request) {
// get the name from web.C
// a request-local context object
// see https://github.com/zenazn/goji/blob/master/web/web.go
name := c.URLParams["name"]
w.Write([]byte(fmt.Sprintf("Hello %s !", name)))
}
func main() {
goji.Get("/", Home)
goji.Get("/:name", SayHello)
// goji default port number is 8000
// change to port number 8080
// with flag.Set
flag.Set("bind", ":8080")
goji.Serve()
}
Sample output :
http://localhost:8080/Grantt
Hello Grantt !
go run gojihttproute.go

NOTE : Nice color coded text logs spitted out by Goji! :-)
