Function ToContextHandler

handler.go:27–52

ToContextHandler transforms f into a ContextHandler. f must be a function with one of the following signatures: func(http.ResponseWriter, *http.Request) func(http.ResponseWriter, *http.Request, func()) func(Context, http.ResponseWriter, *http.Request) func(Context, http.ResponseWriter, *http.Request

(f interface{})

//     func(Context, http.ResponseWriter, *http.Request)
//     func(Context, http.ResponseWriter, *http.Request, func())
func ToContextHandler(f interface{}) ContextHandler {
	switch t := f.(type) {
	case func(Context, http.ResponseWriter, *http.Request, func()):
		return ContextHandler(t)
	case ContextHandler:
		return t
	case func(Context, http.ResponseWriter, *http.Request):
		return func(c Context, w http.ResponseWriter, r *http.Request, q func()) {
			t(c, w, r)
		}
	case func(http.ResponseWriter, *http.Request, func()):
		return func(c Context, w http.ResponseWriter, r *http.Request, q func()) {
			t(w, r, q)
		}
	case func(http.ResponseWriter, *http.Request):
		return func(c Context, w http.ResponseWriter, r *http.Request, q func()) {
			t(w, r)
		}
	case http.Handler:
		return func(c Context, w http.ResponseWriter, r *http.Request, q func()) {
			t.ServeHTTP(w, r)
		}
	default:
		panic(ErrUnsupportedHandler)
	}
}
