A Tour of Go Web servers
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) }
