使用通知数据标记用户

OneSignal.setNotificationOpenedHandler(
  new OneSignal.OSNotificationOpenedHandler() {
    @Override
    public void notificationOpened(OSNotificationOpenedResult result) {
      JSONObject data = result.getNotification().getAdditionalData();
      Log.i("OneSignalExample", "Notification Data: " + data);

      if (data != null) {
        String topic = data.optString("notification_topic", null);
        if (topic != null)
          OneSignal.User.addTag("notification_topic", topic);

        // 如需要，从自定义数据中添加更多标签
        String category = data.optString("category", null);
        if (category != null)
          OneSignal.User.addTag("notification_category", category);
      }
    }
  }
);
```swift Swift
let notificationOpenedBlock: OSHandleNotificationActionBlock = { result in
let payload: OSNotificationPayload? = result?.notification.payload
let additionalData = payload?.additionalData

if let topic = additionalData?["notification_topic"] as? String {
  OneSignal.User.addTags(["notification_topic": topic])
}

if let category = additionalData?["category"] as? String {
  OneSignal.User.addTags(["notification_category": category])
}

// 如需要，从自定义数据中添加更多标签
}
