在功能注册表中调用HTTP函数

Question

I have a func registry but I don't know how can I call a HTTP func on it.

registry := map[string]func(){
    "MyFunc1": MyFunc1,
}
registry["MyFunc1"]()

func MyFunc1(w http.ResponseWriter, r *http.Request) {
    w.Write([]byte("Hi Gorilla!"))
}

I changed them to these:

registry := map[string]func(http.ResponseWriter, *http.Request){
    "MyFunc1": MyFunc1,
}

But I can not call it now!

gorilla.HandleFunc("/", registry["MyFunc1"]()).Name(parentKey)

Answer 1

From, the documentation, HandleFunc expects a func(http.ResponseWriter, *http.Request) type.

However, you have a typo in your code because you are not giving the function as argument, you are calling it:

Change the part registry["MyFunc1"]() into registry["MyFunc1"]
