I see this code:
type HandlerFunc func(ResponseWriter, *Request)
func (f HandlerFunc) ServeHTTP(w ResponseWriter, r *Request) {
f(w, r)
}
i imitate this but my code can not compile:
[john@localhost 01]$ cat inspiration_by_golang_http.go
package main
import "fmt"
type Handler interface {
Call(x, y int)
}
func Add(x, y int) {
fmt.Println(x+y)
}
type HandlerFunc func(x, y int)
func (f HandlerFunc) Call(x, y int) {
f(x, y)
}
func main() {
demo := HandlerFunc{}
var i Handler
i = demo
i.Call(1, 2)
}
[john@localhost 01]$ go run inspiration_by_golang_http.go
# command-line-arguments
./inspiration_by_golang_http.go:17: invalid type for composite literal:
HandlerFunc
Why? I want to know. Thinks!
My computer arch is amd64. OS is linux. Distribution is fc24.
