如何确定类型是否为结构体

本文介绍了如何确定类型是否为结构体的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

假设我有 2 个结构:

Suppose I have 2 structs:

type Base struct { id int name string } type Extended struct { Base Email string Password string }

我想反映扩展结构以获取它的字段:

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

e := Extended{} e.Email = "me@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 Kind() of Value

Just check the Kind() of Value

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