如何打开文件当前位置，弹出资源管理器

public static async openFolder(fileUri: string, context?: context.UIAbilityContext): Promise<void> { 
  let want: Want = { 
    bundleName: ‘com.huawei.hmos.filemanager’, 
    abilityName: ‘MainAbility’, 
    parameters: { 
      ‘fileUri’: fileUri 
    } 
  }; 
  try { 
  context?.startAbilityForResult(want).then((data) => { 
  HiLog.info(tag, 'startAbility data: ’ + JSON.stringify(data)); 
}); 
} catch (error) { 
  HiLog.warn(tag, 'openFolder err = ’ + JSON.stringify(error)); 
  throw error as Error; 
} 
}
