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 stringtype 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 mainimport ( "net/http" "fmt")type String stringtype 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)}
