【中文标题】如何从 Autodesk 模型衍生 API 的响应中识别提取的 obj 文件？【英文标题】：How to identify extracted obj file from response of autodesk model derivative API? 【发布时间】：2019-11-15 18:34:27 【问题描述】：在模型派生 API（使用 DbIds 的 OBJ 提取）中，我使用 API 检索了 OBJ URN。如下 Response 所示，它返回 obj、mtl 及其 zip 的所有子 URN。我们如何识别最近的提取，因为每个孩子都有自己的指导？
我附上了整个响应 JSON。我正在寻找的是第二个 obj 文件，它使用多个 dbid 提取，例如“17,19,21,22,23 ...”。第一个子 obj 是很久以前创建的。如何区分新的 obj.因为每个节点的 GUID 都不同。如何识别哪个 GUID.obj 属于我想要的提取。
** 已编辑 ** 我正在寻找识别提取的波前对象文件（不是从元数据中获取的对象 ID 和名称）。假设如果我从一个模型中提取了 2 个目标文件，那么在完成目标文件几何提取作业后，将生成 6 个文件并存储在存储桶中。
-
第一个 .obj (guid = /output/geometry/e72fa6b3-4fc2-3c86-8424-5d0755539c0d.obj)
第一个.mtl
第一个.zip
第二个.obj
第二个.mtl
第二个.zip
每个文件都有不同的 GUID.Type 作为名称。并且这些 guid 是随机的，并且在调用提取 API 或获取其进度时从未显示。
这些显示在下面的 JSON 文件中。现在假设我从一个模型中提取了 10 个不同的目标文件。这意味着将在桶 30 中生成新文件 URN。 而且越来越难以识别。
解决方案可能是如果我从模型中提取 obj 几何图形，我应该得到那个特定的 obj、mtl、zips guid。如果我只得到 3 个 id，那么我可以映射它们并从存储桶下载它。 现在发生的事情是我在调用 get manifest GET :urn/manifest 后得到了所有 obj 的 guid（假设为 30 ）。而且我不明白哪个 obj 文件属于哪个提取。

【参考方案1】：使用GET :urn/metadata 获取模型视图列表：
"data":
"type": "metadata",
"metadata": [
"name": "Scene",
"role": "3d",
"guid": "4f981e94-8241-4eaf-b08b-cd337c6b8b1f",
,
"name": "Sheet: A101",
"role": "2d",
"guid": "8e7c6bca-cfd1-290e-4b16-f3670169bb71"
]
然后使用GET :urn/metadata/:guid 检索对象树以识别您的派生：
"data":
"type": "objects",
"objects": [
"objectid": 1,
"name": "A5",
"objects": [
"objectid": 2,
"name": "Model",
"objects": [
"objectid": 3,
"name": "Bottom",
"objects": [
"objectid": 4,
"name": "Box"
]

你好@Bryan。感谢您的答复。但我正在寻找别的东西。这为我们提供了所有对象 ID 及其名称，如模型树。我正在寻找识别提取的波前目标文件。如果我从一个模型中提取了 2 个目标文件，那么在完成 obj 提取作业后，将添加 6 个文件。 1. 第一个 .obj 2.first.mtl 3.first.zip 4.second.obj 5.second.mtl 6.second.zip。如 JSON 文件所示。现在假设我从一个模型中提取了 10 个不同的目标文件。这意味着在存储桶 30 中将生成新文件 URN。 所以如果我想看看第 9 个目标文件是什么。我没有句柄，因为 GUID 不匹配。 我已经编辑了这个问题。能否请您尽快查看并回复。 如果您共享了整个清单有效负载，那么只有两组 obj/mtl/zip（其余是缩略图和视图），您可以使用GET :urn/metadata 的名称来识别它们端点或将它们映射到 objectID [547, 924, 942, 977] 和 [17, 19, 21 ... 以交叉引用它们的详细信息并找出它们的身份。以上是关于如何从 Autodesk 模型衍生 API 的响应中识别提取的 obj 文件？的主要内容，如果未能解决你的问题，请参考以下文章
