react native push notification（Android）-通知不断重复，不会停止

Question

我使用的是react-nate-push-通知库。我可以让通知随着振动和声音一起出现......但是问题是它一直重复并且不会停止。

我连续收到20个相同的通知。有人知道为什么会这样吗？

请参阅下面的代码

import PushNotification from 'react-native-push-notification';

  constructor(props) {
    super(props);

    PushNotification.configure({
      onNotification: function(notification) {
        console.log('NOTIFICATION:', notification);
        notification.finish(PushNotificationIOS.FetchResult.NoData);
      },

      popInitialNotification: true,
      requestPermissions: true,
    });

runPushNotification = () => {
    PushNotification.localNotification({
     title: 'title'
     message: 'message',
     playSound: true,
     soundName: 'sound.mp3',
     autoCancel: true, 
     vibrate: true, 
     vibration: 300, 
     actions: '["Yes", "No"]',
     onlyAlertOnce: true,
    });
  };

对我来说，这是消除重复类型解决了问题

  //repeatType: 'day', // (optional) Repeating interval. Check 'Repeating 

 PushNotification.localNotification({
      /* Android Only Properties */
      channelId: '767888', // (required) channelId, if the channel doesn't exist, notification will not trigger.
      ticker: 'My Notification Ticker', // (optional)
      showWhen: true, // (optional) default: true
      autoCancel: true, // (optional) default: true
      largeIcon: 'ic_launcher', // (optional) default: "ic_launcher". Use "" for no large icon.
      largeIconUrl: 'https://www.example.tld/picture.jpg', // (optional) default: undefined
      smallIcon: 'ic_notification', // (optional) default: "ic_notification" with fallback for "ic_launcher". Use "" for default small icon.
      bigText: 'My big text that will be shown when notification is expanded', // (optional) default: "message" prop
      subText: 'This is a subText', // (optional) default: none
      bigPictureUrl: 'https://www.example.tld/picture.jpg', // (optional) default: undefined

      bigLargeIconUrl: 'https://www.example.tld/bigicon.jpg', // (optional) default: undefined
      color: 'red', // (optional) default: system default
      vibrate: true, // (optional) default: true
      vibration: 300, // vibration length in milliseconds, ignored if vibrate=false, default: 1000
      tag: 'some_tag', // (optional) add tag to message
      group: 'group', // (optional) add group to message
      groupSummary: false, // (optional) set this notification to be the group summary for a group of notifications, default: false
      ongoing: false, // (optional) set whether this is an "ongoing" notification
      priority: 'high', // (optional) set notification priority, default: high
      visibility: 'private', // (optional) set notification visibility, default: private
      ignoreInForeground: false, // (optional) if true, the notification will not be visible when the app is in the foreground (useful for parity with how iOS notifications appear). should be used in combine with `com.dieam.reactnativepushnotification.notification_foreground` setting
      shortcutId: 'shortcut-id', // (optional) If this notification is duplicative of a Launcher shortcut, sets the id of the shortcut, in case the Launcher wants to hide the shortcut, default undefined
      onlyAlertOnce: false, // (optional) alert will open only once with sound and notify, default: false

      when: null, // (optional) Add a timestamp (Unix timestamp value in milliseconds) pertaining to the notification (usually the time the event occurred). For apps targeting Build.VERSION_CODES.N and above, this time is not shown anymore by default and must be opted into by using `showWhen`, default: null.
      usesChronometer: false, // (optional) Show the `when` field as a stopwatch. Instead of presenting `when` as a timestamp, the notification will show an automatically updating display of the minutes and seconds since when. Useful when showing an elapsed time (like an ongoing phone call), default: false.
      timeoutAfter: null, // (optional) Specifies a duration in milliseconds after which this notification should be canceled, if it is not already canceled, default: null

      messageId: 'google:message_id', // (optional) added as `message_id` to intent extras so opening push notification can find data stored by @react-native-firebase/messaging module.

      actions: ['Yes', 'No'], // (Android only) See the doc for notification actions to know more
      invokeApp: true, // (optional) This enable click on actions to bring back the application to foreground or stay in background, default: true

      /* iOS only properties */
      category: '', // (optional) default: empty string

      /* iOS and Android properties */
      id: 0, // (optional) Valid unique 32 bit integer specified as string. default: Autogenerated Unique ID
      title: 'My Notification Title', // (optional)
      message: 'My Notification Message', // (required)
      userInfo: {}, // (optional) default: {} (using null throws a JSON value '<null>' error)
      playSound: false, // (optional) default: true
      soundName: 'default', // (optional) Sound to play when the notification is shown. Value of 'default' plays the default sound. It can be set to a custom sound such as 'android.resource://com.xyz/raw/my_sound'. It will look for the 'my_sound' audio file in 'res/raw' directory and play it. default: 'default' (default sound is played)
      number: 10, // (optional) Valid 32 bit integer specified as string. default: none (Cannot be zero)
      //repeatType: 'day', // (optional) Repeating interval. Check 'Repeating Notifications' section for more info.
    });

对于未来的观众来说，如果你收到通知，有两种方式可以实现，一种是来自外部服务器的推送通知，另一种是从你的应用程序自己的代码创建的本地通知。

如果您收到推送通知，那么您需要检查您的服务器端逻辑，看看您没有触发它们太多次。

如果这些是本地通知，请在代码中搜索您调用通知的任何位置。

做这两件事应该会导致它被过度调用。
