模型导数 API Post 作业 - 400 错误请求 "Invalid 'design' parameter"

Model Derivative API Post Job - 400 Bad Request "Invalid 'design' parameter"

我已将 Revit 模型上传到我的 OSS 存储桶并尝试将文件转换为 svf,但我得到以下信息:

400 错误请求 {"diagnostic":"Invalid 'design' parameter."}

我是 Forge 的新手 API,不确定哪里需要设计参数或它指的是哪里,所以任何指导将不胜感激。

有人遇到过类似的问题

正如我们所讨论的,导致此问题的主要原因是在将上传文件的 objectId 转换为 base64URN 时缺少 urn:

通过PUT buckets/:bucket_key/objects/:object_name将模型文件上传到Forge OSS bucket后,您将得到如下响应:

{
    "bucketKey": "mybucket",
    "objectId": "urn:adsk.objects:os.object:mybucket/rac_basic_sample_project.rvt",
    "objectKey": "rac_basic_sample_project.rvt",
    "sha1": "6d0defe9c4f8e36c7786254a3d07f9991dbf8d91",
    "size": 16474112,
    "contentType": "application/octet-stream",
    "location": "https://developer.api.autodesk.com/oss/v2/buckets/mybucket/objects/rac_basic_sample_project.rvt"
}

上传模型的URN将是上面响应中的objectId,即urn:adsk.objects:os.object:mybucket/rac_basic_sample_project.rvt。在通过 API POST job, the objectId must have to encoded by Base64 encoder(e.g. this tool) 触发模型翻译之前,它变成如下:

但是有两个无效符号,即base64编码URN末尾的两个=。您必须如下所示删除它们并使用这个 URL-safe Base64 (no padding) 版本的 URN 来触发 Forge MD API.

的翻译工作
