使用反射确定类型是否为字符串

Question

Some of the existing answers on here about how to determine the type of an object at runtime..god help us

if reflect.TypeOf(err) ==  string {

}

that doesn't compile

if reflect.TypeOf(err) ==  "string" {

}

neither does that or this:

if reflect.TypeOf(err).Kind() ==  "string" {

}

how do we do this?

If I use the typeof function given by one of the answers, I get:

Answer 1

Compare like string

if reflect.TypeOf(err).String() == "string" {
    fmt.Println("hello")
}

Or using type assertions

type F = func()

func typeof(v interface{}) string {
    switch v.(type) {
    case int:
        return "int"
    case string:
        return "string"
    case F:
        return "F"
    //... etc
    default:
        return "unknown"
    }
}

Then

var f F
if typeof(f) == "F"{
    fmt.Println("hello F")
}
