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) }
