如何使用反射初始化struct的map字段

type Person struct {
    Name string
    Age  int
}

p := Person{}
t := reflect.TypeOf(p)

v := reflect.New(t).Elem()

for i := 0; i < t.NumField(); i++ {
    field := t.Field(i)
    if field.Type.Kind() == reflect.Map {
        // 处理map字段
    }
}

mapType := reflect.MapOf(reflect.TypeOf(""), reflect.TypeOf(0))
mapValue := reflect.MakeMap(mapType)
v.Field(i).Set(mapValue)

mapValue.SetMapIndex(reflect.ValueOf("key"), reflect.ValueOf(123))

package main

import (
    "fmt"
    "reflect"
)

type Person struct {
    Name string
    Age  int
    Info map[string]interface{}
}

func main() {
    p := Person{}
    t := reflect.TypeOf(p)
    v := reflect.New(t).Elem()

    for i := 0; i < t.NumField(); i++ {
        field := t.Field(i)
        if field.Type.Kind() == reflect.Map {
            mapType := reflect.MapOf(reflect.TypeOf(""), reflect.TypeOf((*interface{})(nil)).Elem())
            mapValue := reflect.MakeMap(mapType)
            v.Field(i).Set(mapValue)
        }
    }

    v.FieldByName("Info").SetMapIndex(reflect.ValueOf("key"), reflect.ValueOf("value"))

    fmt.Println(v.Interface())
}
