如何確定是否類型是Golang

Question

一個struct

假設我有2層結構：

type Base struct { 
id int 
name string 
} 

type Extended struct { 
Base 
Email string 
Password string 
} 

，我想反映擴展的結構來得到它的領域：

e := Extended{} 
e.Email = "me@mail.com" 
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)) 
    } 
} 

Answer 1

只需選中類（）價值

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