如何使用 Golang 结构体反射机制实现不同结构体字段值的获取和赋值？

package main

import (
    "fmt"
    "reflect"
)

type person struct {
    name      string
    age       uint8
    married   bool
    hobbies   []string
    education map[string]string
}

func main() {
    a := person{
        name:      "john",
        age:       19,
        married:   false,
        hobbies:   []string{"dance", "music"},
        education: map[string]string{"university": "xx school"},
    }
    b := person{
        name:      "jim",
        age:       19,
        married:   false,
        hobbies:   []string{"singing", "music"},
        education: map[string]string{"university": "xx school"},
    }
    c := person{}

    // 获取结构体的 reflect.value 和 reflect.type 对象
    avalue := reflect.valueof(a)
    atype := reflect.typeof(a)

    bvalue := reflect.valueof(b)

    // 需要使用 c 的引用，因为后面需要给 c 赋值
    cvalue := reflect.valueof(&c)

    // 遍历结构体的字段
    for i := 0; i < avalue.numfield(); i++ {
        // 获取当前字段的 value 和 type 对象
        afield := avalue.field(i)
        afieldtype := atype.field(i)

        // 获取 b 结构体对应字段的 value 对象
        bfield := bvalue.field(i)

        // 打印不同字段的信息
        fmt.printf("%v: %v - %v\n", afieldtype.name, afield.interface(), bfield.interface())
        fmt.printf("========================\n")

        // 对切片和 map 类型进行特殊处理
        switch afield.kind() {
        case reflect.map:
            // 断言成 map 类型，比较键值对
            aedu := afield.interface().(map[string]string)
            bedu := bfield.interface().(map[string]string)
            fmt.printf("%+v - %+v\n", aedu, bedu)
        case reflect.slice:
            // 用类似方式处理切片
        default:
            // 其他类型的字段，直接赋值给 c
            if afield.interface() != bfield.interface() {
                cvalue.elem().field(i).set(afield)
            } else {
                cvalue.elem().field(i).set(bfield)
            }
        }
    }
    fmt.printf("%+v\n", c)
}
