HarmonyOS 获取网络的信息不准确

发现网络是portal时会触发netCapabilitiesChange的事件，所以需要再监听一下netCapabilitiesChange事件才能准确的判断当前连接是不是需要登录验证，新增的代码如下:

this.netConnection.on('netCapabilitiesChange', ((data: connection.NetCapabilityInfo) => {
  let netCapabilities = data.netCap
  if (netCapabilities.networkCap) {
    netCapabilities.networkCap.forEach((item) => {
      if (item === 17) {
        AppStorage.setOrCreate('app_networkState', false)
      }
    })
  }
}));
