go 2个多层嵌套的map取并集

使用递归取2个map并集，适用于写一个map去替换一个固定模版的map里的值（接口参数化替换等）
可能还存在bug。目前测试，见Test用例。

func MapSwitch(map01, map02 map[string]interface{}) map[string]interface{}{
    /**
     * @Description: 2个嵌套map取并集处理；map01：新的map数据，map02：待替换的map数据
                    PS：需保证map01和map02嵌套中的[]interface{}中对应下标的数据类型一致
     */
    for k, v := range map01{
        if _, ok := map02[k]; ok{
            switch v.(type) {
            case map[string]interface{}:
                MapSwitch(v.(map[string]interface{}), map02[k].(map[string]interface{}))
            case []interface{}:
                res := InterfaceSwitch(v.([]interface{}), map02[k].([]interface{}))

            default:
                map02[k] = v
            }
        }else{
            map02[k] = v
        }
    }
    return map02
}

func InterfaceSwitch(interface01, interface02 []interface{})[]interface{}{
    /**
     * @Description: interface01：新的数据，interface02：待替换的数据
     */
    for k, v := range interface01{
        if k <= len(interface02) -1 {
            switch v.(type) {
            case map[string]interface{}:
                res := MapSwitch(v.(map[string]interface{}), interface02[k].(map[string]interface{}))
                newInterface = append(newInterface, res)
            case []interface{}:
