如何确定类型是否为Golang中的结构 [英] How to determine if type is a struct in Golang

问题描述

假设我有2个结构:

type Base struct {
 id int
 name string
}

type Extended struct {
 Base
 Email string
 Password string
}

我想反映扩展结构来获取它的字段:

And i want to reflect the Extended struct to get it's field :

e := Extended{}
e.Email = "[e-mail]"
e.Password = "secret"

for i := 0 ; i < reflect.TypeOf(e).NumField() ; i++ {
  if reflect.TypeOf(e).Field(i) != "struct" {  << how to do this validation?
    fmt.Println(reflect.ValueOf(e).Field(i))
  }
}

推荐答案

只需检查Value的Kind()

Just check the Kind() of Value

if reflect.ValueOf(e).Field(i).Kind() != reflect.Struct {
    fmt.Println(reflect.ValueOf(e).Field(i))
}
