import NotificationManager from '@ohos.notificationManager';

let notificationRequest = { 
  id: 1, 
  content: { 
    contentType: NotificationManager.ContentType.NOTIFICATION_CONTENT_BASIC_TEXT, // 普通文本类型通知 
    normal: { 
      title: 'test_title', 
      text: 'test_text', 
      additionalText: 'test_additionalText', 
    } 
  } 
} 
 
NotificationManager.publish(notificationRequest, (err) => { 
  if (err) { 
    console.error(`[ANS] failed to publish, error[${err}]`); 
    return; 
  } 
  console.info(`[ANS] publish success`); 
}); 
let notificationRequest = { 
  id: 1, 
  content: { 
    contentType: NotificationManager.ContentType.NOTIFICATION_CONTENT_LONG_TEXT, // 长文本类型通知 
    longText: { 
      title: 'test_title', 
      text: 'test_text',

      briefText: 'test_briefText', 
      expandedTitle: 'test_expandedTitle', 
    } 
  } 
} 
// 发布通知 
NotificationManager.publish(notificationRequest, (err) => { 
  if (err) { 
    console.error(`[ANS] failed to publish, error[${err}]`); 
    return; 
  }
