HarmonyOS Web加载本地沙箱资源H5文件报错

在web组件加下setpathallowinguniversalaccess属性

.onControllerAttached(() => {
  try {
    // 设置允许可以跨域访问的路径列表
    this.webController.setPathAllowingUniversalAccess([
      this.FILE_DIR
    ])
    // this.webController.loadUrl("file://" + getContext().resourceDir + "/index.html")
  } catch (error) {
    console.error(`ErrorCode: ${(error as BusinessError).code}, Message: ${(error as BusinessError).message}`);
  }
})
