在GO中将字符串转换为函数名称? [重复]

This question already has an answer here:

I am creating a Restful API.

I am passing function name and arguments in JSON

eg. "localhost/json_server?method=foo&id=1"

Lets say, i have a simple go server running

 http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {                                                                             
     fmt.Println("path",r.URL.Path )                                                                                                             
     fmt.Fprintf(w, "Hello, %q", html.EscapeString(r.URL.Path))                                                                                  
function json_server(){

The r.url.Path will give me "json_server" in string. Now i want to first check if the function exists , if exists call the function as defined else throw some exception.

Is this possible to do ?

When i am doing python and i use getattr(method,args) to call the method and arguments which are in string.

I have developed interest in Go after using Docker. Any help will be appreciated.
