如何在golang中删除JSON数组中的元素？

package main

import (
	"encoding/json"
	"fmt"
)

type Person struct {
	Name string `json:"name"`
	Age  int    `json:"age"`
}

func main() {
	// 原始JSON数据
	jsonData := `[{"name":"Alice","age":25},{"name":"Bob","age":30},{"name":"Charlie","age":35}]`

	// 解析JSON数据
	var people []Person
	err := json.Unmarshal([]byte(jsonData), &people)
	if err != nil {
		fmt.Println("解析JSON数据失败：", err)
		return
	}

	// 删除元素
	indexToRemove := 1
	if indexToRemove >= 0 && indexToRemove < len(people) {
		people = append(people[:indexToRemove], people[indexToRemove+1:]...)
	}

	// 序列化为JSON
	modifiedJSON, err := json.Marshal(people)
	if err != nil {
		fmt.Println("序列化为JSON失败：", err)
		return
	}

	fmt.Println(string(modifiedJSON))
}
