反映以测试值是否为字符串

Question

I'm trying to test if a value coming from the gjson library is a string in the quickest and simplest way possible. I don't want to use a switch type assertion.

if reflect.TypeOf(gjson.Get(input, "name").Value()) != "string" {
    return "Not a string!"  
}

What's wrong with my code?

gjson.Get returns a Result, so you can simply check its Type field:

if gjson.Get(input, "name").Type != gjson.String {
    return "Not a string!"  
}
