如何使用reflect.TypeOf（[] string {“ a”}）。Elem（）？

Question

I'm really new to golang and I'm struggling with the basics. I wrote a piece of code like this:

package main
import (
  "log"
  "reflect"
)

if reflect.TypeOf([]string{"a"}).Elem() == reflect.String {
  log.Println("success")
}
if reflect.TypeOf([]int{1}).Elem() == reflect.Int{
  log.Println("success")
}
if reflect.TypeOf([]float64{1.00}).Elem() == reflect.Float64 {
  log.Println("success")
}

When I run this code, I get the error

invalid operation: reflect.TypeOf([]string literal).Elem() == reflect.String (mismatched types reflect.Type and reflect.Kind)

I don't understand the documentation https://golang.org/pkg/reflect/ because I can't find examples of how to reference the different "types" or "kinds"

How should I be writing my if statements to do the comparisons I'm attempting?

Answer 1

reflect.Type is an interface with a method called Kind(). As per document:

    // Kind returns the specific kind of this type.
    Kind() Kind

So you should write :

if reflect.TypeOf([]string{"a"}).Elem().Kind() == reflect.String {
  log.Println("success")
}
