如何使用反射设置嵌套结构字段值

import "reflect"

type InnerStruct struct {
    InnerField string
}

type OuterStruct struct {
    OuterField InnerStruct
}

outer := OuterStruct{
    OuterField: InnerStruct{
        InnerField: "initial value",
    },
}

outerValue := reflect.ValueOf(&outer).Elem()

innerValue := outerValue.FieldByName("OuterField")

innerValue = reflect.Indirect(innerValue)

innerFieldValue := innerValue.FieldByName("InnerField")

innerFieldValue.SetString("new value")

fmt.Println(outer)

package main

import (
    "fmt"
    "reflect"
)

type InnerStruct struct {
    InnerField string
}

type OuterStruct struct {
    OuterField InnerStruct
}

func main() {
    outer := OuterStruct{
        OuterField: InnerStruct{
            InnerField: "initial value",
        },
    }

    outerValue := reflect.ValueOf(&outer).Elem()
    innerValue := outerValue.FieldByName("OuterField")
    innerValue = reflect.Indirect(innerValue)
    innerFieldValue := innerValue.FieldByName("InnerField")
    innerFieldValue.SetString("new value")

    fmt.Println(outer)
}
