模型衍生API发布作业-400错误的请求“无效的'design'参数” [英] Model Derivative API Post Job - 400 Bad Request "Invalid 'design' parameter"

问题描述

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

I've uploaded a Revit model to my OSS bucket and trying to translate the file to svf, but I'm getting the following:

400错误请求{ diagnostic：无效的'design'参数。}

400 Bad Request {"diagnostic":"Invalid 'design' parameter."}

我是Forge API的新手，不确定是否需要设计参数或在何处引用设计参数，因此任何指导都将不胜感激。

I'm new to the Forge API and not sure where a design parameter is required or where it's referring to, so any guidance would be appreciated.

推荐答案

对于某人遇到了类似的问题

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

As we per discussed, the main reason caused this issue is missing the urn: while transforming the uploaded file's objectId into base64URN.

通过将模型文件上传到Forge OSS存储桶后href = https://developer.autodesk.com/en/docs/data/v2/reference/http/buckets-:bucketKey-objects-:objectName-PUT rel = nofollow noreferrer> PUT桶/：bucket_key / objects /：object_name ，您将获得如下响应：

After uploading model file on to Forge OSS bucket via PUT buckets/:bucket_key/objects/:object_name, you will obtain a response like this:

{
    "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"
}

上载模型的URN将为上述响应中的 objectId ，即 urn：adsk.objects：os.object：mybucket / rac_basic_sample_project。 rvt 。通过API触发模型转换之前 POST作业，必须使用Base64编码器对 objectId 进行编码（例如，此工具），它就会变成以下内容：

The URN of the uploaded model will be the objectId in above response, i.e. urn:adsk.objects:os.object:mybucket/rac_basic_sample_project.rvt. Before trigger model translation via API POST job, the objectId must have to encoded by Base64 encoder(e.g. this tool) and it becomes the below:

但是有两个无效符号，即两个 = base64编码的URN的末尾。您必须按照以下说明删除它们，并使用此URN（ URL安全的Base64（无填充）版本）来触发Forge MD API的翻译工作。

But there are two invalid symbols, i.e. the two = at the end of the base64 encoded URN. You must have to remove them as below and use this URN which is a URL-safe Base64 (no padding) version to trigger a translation job of the Forge MD API.
