Package http serves HTTP requests using any value that implementshttp.Handler
:
package http type Handler interface {
ServeHTTP(w ResponseWriter, r *Request)
}
In this example, the type Hello
implements http.Handler
.
Visit http://localhost:4000/ to see the greeting.
Note: This example won't run through the web-based tour user interface. To try writing web servers you may want to Install Go.
package main import (
"fmt"
"net/http"
) type Hello struct {} func (h Hello) ServeHTTP(
w http.ResponseWriter,
r *http.Request) {
fmt.Fprint(w, "Hello!")
} func main() {
var h Hello
http.ListenAndServe("localhost:4000",h)
}
