模型衍生API发布作业

本文介绍了模型衍生API发布作业-400错误的请求“无效的'design'参数”的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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.

POST developer.api.autodesk/modelderivative/v2/designdata/job Headers Authorization: Bearer {AccessToken} Content-Type: application/json Body { "input": { "urn": "{MyDesignBase64Urn}", "compressedUrn": false, "rootFilename": "test-project.rvt" }, "output": { "destination": { "region": "us" }, "formats": [ { "type": "svf", "views": [ "2d", "3d" ] } ] } }

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 = developer.autodesk/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": "developer.api.autodesk/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.
