A Tour of Go Exercise: HTTP Handlers

Implement the following types and define ServeHTTP methods on them. Register them to handle specific paths in your web server.

type String string

type Struct struct {
    Greeting string
    Punct    string
    Who      string
}

For example, you should be able to register handlers using:

http.Handle("/string", String("I'm a frayed knot."))
http.Handle("/struct", &Struct{"Hello", ":", "Gophers!"})

package main

import (
    "net/http"
    "fmt"
)
type String string

type Struct struct {
    Greeting string
    Punct    string
    Who      string
}

func (h Struct) ServeHTTP(
    w http.ResponseWriter,
    r *http.Request) {
    fmt.Fprint(w, h)
}
func (s String) ServeHTTP(
    w http.ResponseWriter,
    r *http.Request) {
    fmt.Fprint(w, s)
}

func main() {
    http.Handle("/string", String("I'm a frayed knot."))
    http.Handle("/struct", &Struct{"Hello", ":", "Gophers!"})
    // your http.Handle calls here
    http.ListenAndServe("localhost:4000", nil)

}
