HarmonyOS 鸿蒙Next混淆后resourceManager取不到资源
<markdown _ngcontent-dvn-c237="" class="markdownPreContainer">

在Har包的某个页面的aboutToAppear()中，通过以下代码获取相应资源：

try {

    let res:Resource = $r('app.media.correct');
    let id = res.id;
    console.info(`res = ${res}, id = ${id}`)
    //let drawableDescriptor  = //getContext(this).resourceManager.getDrawableDescriptor(0x02000099);
      let drawableDescriptor = getContext(this).resourceManager.getDrawableDescriptor(id);

     let temp = drawableDescriptor.getPixelMap(); //获取PixelMap后做处理...
     
      console.info('Succeed in creating pixelmap.')
     
 } catch (e) {
    let error = e as BusinessError;
    console.error('Failed to create pixelmap: ' + error.code + ', ' + error.message)
    }
<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 4px; right: 8px; font-size: 14px;">复制</button>

日志： 主工程引har包，har为debug，或release下关闭混淆，都调用正常 res = [object Object]，id = 16777387 Succeed in creating pixelmap.

一旦har包开启混淆: res = [object Object]，id = -1 Failed to create pixelmap: 9001001, Resource id invalid

注：

1. 混淆文件中没有写内容；
2. 混淆后的resourceTable.h中：

   const int32_t MEDIA_CORRECT = 0x02000099;
   <button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 4px; right: 8px; font-size: 14px;">复制</button>

   放开注释的代码行依然报错
