Question

我是vue-native和vuejs的新手，想与他们一起创建一个应用程序。我想向应用程序添加推送通知。我使用this教程来添加推送通知并对其进行测试，但出现此错误

创建的挂钩中出现错误：“ TypeError： this.registerForPushNotificationsAsync不是一个函数。（在 'this.registerForPushNotificationsAsync（）'， 'this.registerForPushNotificationsAsync'未定义）“

我在app.vue文件中像这样在我的项目中添加这段代码

    <template>
    <view class="container">
        <text class="text-color-primary">{{JSON.stringify(notification.data)}}</text>
    </view>
</template>

<script>

export default {
  data: function() {
      return {
        notification: {}
      };
    },
    created: function() {
       this.registerForPushNotificationsAsync();
       this._notificationSubscription = Notifications.addListener(
         this._handleNotification
       );
     },

     methods:{
       _handleNotification: function(notification) {
         this.notification = notification;
       },
       registerForPushNotifications: async function() {
         const { status: existingStatus } = await Permissions.getAsync(
           Permissions.NOTIFICATIONS
         );
         let finalStatus = existingStatus;

         // only ask if permissions have not already been determined, because
         // iOS won't necessarily prompt the user a second time.
         if (existingStatus !== "granted") {
           // Android remote notification permissions are granted during the app
           // install, so this will only ask on iOS
           const { status } = await Permissions.askAsync(
             Permissions.NOTIFICATIONS
           );
           finalStatus = status;
         }

         // Stop here if the user did not grant permissions
         if (finalStatus !== "granted") {
           return;
         }

         // Get the token that uniquely identifies this device
         Notifications.getExpoPushTokenAsync().then(token => {
           console.log(token);
         });
       }
     }
};



</script>

我哪里出错了？

使用vue-native和expo发送推送通知
