Autodesk Forge從轉換的DWG中獲取清單和元數據

Question

我的目標是將DWG文件轉換為可在Forge Viewer中使用並進行標記。 在獲取所有使用脫機查看器的正確文件的過程中，我正在嘗試獲取文件的清單和元數據。 我想要元數據，以便可以訪問用於標記的多邊形ID。 當我調用元數據時，它變成空的。 我究竟做錯了什么？

我已經在DWG文件上上傳並發送了SVF轉換作業請求。

請注意，使用node.js提取器示例對同一文件可以很好地工作，並且提取器創建manifest.json.gz和metadata.json.gz。 我只想了解那些是如何創建的以及如何調用REST。

不幸的是，模型派生API尚不支持2D文檔的元數據，例如.dwg。 我們正在努力在即將發布的API版本中提供此功能。

我暫時認為唯一的解決方法是下載軟件包並“反向工程”內容。 您可以看一下我的NPM軟件包下載方法的實現 ，該方法仍在使用v1 API，但可以正常使用。 這應該給您一個關於如何下載svf資源的好主意。
