HarmonyOS VPN相关能力？

Question

当前正在基于VpnExtensionAbility开发一款vpn相关能力的应用，想咨询一下，在通过VpnExtension.startVpnExtensionAbility拉起的vpn进程内，能否主动关闭当前vpn进程。第二个问题是，通过借鉴提供的VPN demo中，发现没有添加路由的相关操作。在尝试自己添加路由时，发现路由结构RouteInfo有一个成员变量interface，理解应该是填当前虚拟网卡的名称，当时没有看到相关获取当前创建的虚拟网卡的名称的api。请提供一份创建路由表并添加的示例代码。

Answer 1

1.可以主动关闭当前vpn进程。

2.interface是开发者自己命名的，可以写成定值。

config配置的示例如下：

         "address": {

         "prefixLength": 32
     }
