有谁知道如何获取状态栏高度

//获取当前窗口 
let windowClass = await window.getLastWindow(getContext(this)); 
//如果没设置全屏就需要设置全屏（非全屏状态下窗口和系统状态栏没有重叠） 
await windowClass.setWindowLayoutFullScreen(true) 
 
let type = window.AvoidAreaType.TYPE_SYSTEM; 
try { 
  let avoidArea = windowClass.getWindowAvoidArea(type); 
  console.log("height: " + avoidArea.topRect.height) 
} catch (exception) { 
  console.error('Failed to obtain the area. Cause:' + JSON.stringify(exception)); 
}
