Sorry, but the page you were trying to view does not exist.
```
controller/home.go
```go
...
r.NotFoundHandler = http.HandlerFunc(notfoundHandler)
r.HandleFunc("/404", notfoundHandler)
...
func notfoundHandler(w http.ResponseWriter, r *http.Request) {
flash := getFlash(w, r)
message := vm.NotFoundMessage{Flash: flash}
tpl, _ := template.ParseFiles("templates/404.html")
tpl.Execute(w, &message)
}
...
```
运行程序，在浏览器中输入一个没有指定的 url，例如: `http://127.0.0.1:8888/nosuchpage`
