java - Autodesk Forge 从转换后的 DWG 中获取 list 和元数据

Question

我的目标是将 DWG 文件转换为可在 Forge Viewer 中使用并带有标记。在获取使用离线查看器的所有正确文件的过程中，我试图获取该文件的 list 和元数据。我想要元数据，以便我可以访问多边形 ID 进行标记。当我调用元数据时，它显示为空。我做错了什么？

我已上传并发送了 DWG 文件的 SVF 转换作业请求。

请注意，使用 node.js 提取器示例，它可以很好地处理同一文件，并且提取器会创建 manifest.json.gz 和metadata.json.gz 。我只是想了解它们是如何创建的以及 REST 调用的方式。

遗憾的是，模型衍生 API 尚不支持 2D 文档的元数据，例如 .dwg。我们正在努力在即将推出的 API 版本中提供此功能。

目前我想唯一的解决方法是下载软件包并对内容进行“逆向工程”。你可以看一下我的npm包download method implementation ，这仍然使用 v1 API，但完全可以工作。这应该能让您了解如何下载 svf 资源。
