问题描述
我们的文件位于 BIM 360 容器中。我们正在尝试创建使用 BIM360 文件并将其显示在浏览器中的查看器应用程序，Forge 站点中提供的用于查看器的示例代码在我们的本地环境中运行良好，但我们在同一应用程序中访问 BIM360 urn 时遇到问题（我们也已经尝试过使用 3-legged 身份验证令牌）。您能否指导我们为存储在 BIM360 容器中的文件获取正确的 URN？请在BIM360中找到属于DWG文件的示例URN（我们在查看器应用程序中访问时已转换为base64），请告诉我们是否正确。
urn:adsk.objects:os.object:wip.dm.prod/7c21a6f0-41c9-42ae-a2b2-4b5741fa4d0c.dwg urn:adsk.objects:os.object:wip.dm.prod/9ece42b9-c71c-4a27-90bb-87775f370164.dwg
