I'm trying to call a function using reflection based on it's name.
I first recover the function with
f := reflect.ValueOf(s).MethodByName(name)
I do error control on the function name by checking if "f" is valid with
if !f.IsValid() {
return errors.New("There is no function with that name")
}
And finally I perform the call with
f.Call(inputs)
My challenge is that inputs depends on the user, and sometimes they can put too many parameters, too little or invalid types.
IE:
2019/01/04 16:47:54 http: panic serving [::1]:53662: reflect: Call using string as type int
How can I control that the inputs are valid before performing the call? Maybe there is a way to recover the expected inputs in my method and check them against the provided ones?
