Golang结构变量中Field的访问地址 [英] Access address of Field within Structure variable in Golang

问题描述

如何访问GOLANG中STRUCTURE中指针或FIELD的地址。我有整个结构变量的地址或指针，但无法正确访问结构中字段的地址。到目前为止，我已经尝试了反射，但似乎打破了某处。

How to access the pointer or the address of a FIELD within a STRUCTURE in GOLANG. I have the address or pointer of the whole structure variable but can not properly access the address of the field inside structure. So far I have tried Reflection but seems breaking somewhere. Any help is highly appreciated.

例如，

For example,

package main

import (
    "fmt"
)

type S struct{ F1, F2 int }

func main() {
    s := new(S)
    f1, f2 := &s.F1, &s.F2
    fmt.Printf("%p %p %p\n", s, f1, f2)
}

<输出：

Output:

0x1040a128 0x1040a128 0x1040a12c
