把pages第一个页面设置成一个loading来处理隐私弹窗的问题

<view>
  <loading></loading>
  <privacyPopup></privacyPopup>
</view>
<script>
export default {

async onLoad(options) {
  try {
    if (wx.onNeedPrivacyAuthorization) {
//getPrivacySetting不支持Promise转了一下Promise
      let {needAuthorization} = await toPromise(wx.getPrivacySetting)({})
      if (needAuthorization) {
//此处要有剪切板权限 也可以是任意隐私权限的接口
        await wx.getClipboardData({})
      }

    }
  } finally {
    
    //此处同意后的跳转逻辑
      }
      
      }
}
</script>
