合并具有公共键golang的两个JSON数组

package main

import (
	"encoding/json"
	"fmt"
)

func main() {
	// 假设有两个JSON数组
	jsonStr1 := `[{"id": 1, "name": "Alice"}, {"id": 2, "name": "Bob"}]`
	jsonStr2 := `[{"id": 1, "age": 25}, {"id": 2, "age": 30}]`

	// 解析JSON数组为对应的Go数据结构
	var array1 []map[string]interface{}
	var array2 []map[string]interface{}
	json.Unmarshal([]byte(jsonStr1), &array1)
	json.Unmarshal([]byte(jsonStr2), &array2)

	// 创建新的JSON数组
	mergedArray := []map[string]interface{}{}

	// 合并具有公共键的元素
	for _, elem1 := range array1 {
		key := elem1["id"]
		for _, elem2 := range array2 {
			if elem2["id"] == key {
				mergedElem := mergeElements(elem1, elem2)
				mergedArray = append(mergedArray, mergedElem)
				break
			}
		}
	}

	// 转换为JSON字符串
	mergedJSON, _ := json.Marshal(mergedArray)
	fmt.Println(string(mergedJSON))
}

// 合并两个元素
func mergeElements(elem1, elem2 map[string]interface{}) map[string]interface{} {
	mergedElem := map[string]interface{}{}
	for k, v := range elem1 {
		mergedElem[k] = v
	}
	for k, v := range elem2 {

	return mergedElem
