How to do it…

In this recipe, we will define three routes, such as /, /login, and /logout along with their handlers. Perform the following steps:

1. Create http-server-basic-routing.go and copy the following content:

package main
import 
(
  "fmt"
  "log"
  "net/http"
)
const 
(
  CONN_HOST = "localhost"
  CONN_PORT = "8080"
)
func helloWorld(w http.ResponseWriter, r *http.Request) 
{
  fmt.Fprintf(w, "Hello World!")
}
func login(w http.ResponseWriter, r *http.Request) 
{
  fmt.Fprintf(w, "Login Page!")
}
func logout(w http.ResponseWriter, r *http.Request) 
{
  fmt.Fprintf(w, "Logout Page!")
}
func main() 
{
  http.HandleFunc("/", helloWorld)
  http.HandleFunc("/login", login)
  http.HandleFunc("/logout", logout)
  err := http.ListenAndServe(CONN_HOST+":"+CONN_PORT, nil)
  if err != nil 
  {
    log.Fatal("error starting http server : ", err)
    return
  }
}

2. Run the program with the following command:

$ go run http-server-basic-routing.go
