Update File Version with Autodesk API

问题

I am now able to upload a file and create an initial version for the file but am unable to update the version. Using the code in Step 6 of this tutorial does not work even after replacing versions:autodesk.core:File with versions:autodesk.bim360:File. From the error message, Request contains 0 includes instead of 1, it seems I need part of the included block from the example in Step 5 but I am not sure what it should look like; given the outer relationships blocks do not match in format between Steps 5 and 6, I am assuming the inner content varies as well.

def create_version_for_file(self, project_name, file_name, folder_id, object_id, storage_id):
    project_id = self.get_project_id_by_name(project_name)
    existing_object_id = self.get_version_id_for_file_in_folder(project_name, folder_id, file_name)
    url = '{}data/v1/projects/{}/items'.format(self.DOMAIN, project_id)
    logger.info('Starting version create at %s for file_name %s, folder %s, object %s',
                url, file_name, folder_id, object_id)
    if existing_object_id:
        logger.info('Creating version for existing object')
        data = self._get_version_data_for_existing_file(file_name, object_id, storage_id)
    else:
        logger.info('Creating version for new object')
        data = self._get_version_json_for_new_file(file_name, folder_id, object_id)
    response = self.session.post(url, json=data, headers={
        'content-type': 'application/vnd.api+json',
        'accept': 'application/vnd.api+json'
    })
    if response.status_code != status.HTTP_201_CREATED:
        logger.warn('Version create for %s failed with status %s: %s', file_name, response.status_code,
                    response.content)
        return None
    return json.loads(response.content)

回答1:

Your payloads are correct. To create the second version, you have to send your request to the CreateVersion endpoint.

    url = '{}data/v1/projects/{}/versions'.format(self.DOMAIN, project_id)

回答2:

You must be missing a little detail that makes it not working, but since you provide so little description nobody can tell based on that ... In order to create a new version, you first need to create a new storage location, upload the file to that location, and post a new version, referencing the existing item id.

Alternatively take a look my that node js sample to upload a file and create a new item or version if the item exists.

The data for your updating the version seems incorrect to me, Try the following steps.

Create a new Storage location on the same folder where V1 of your file is located
upload v2 of your file to the new storage location created on the step below.
Get the item ID of the resource from the manifest result of your successful upload of V1 or call the following end point to obtain the ID https://developer.autodesk.com/en/docs/data/v2/reference/http/projects-project_id-folders-folder_id-contents-GET

Once you have all this information your data to pass in will look like this.

{
"jsonapi": { "version": "1.0" },
"data": {
  "type": "versions",
  "attributes": {
     "name": "v2File.rvt",
     "extension": { "type": "versions:autodesk.bim360:File", "version": "1.0"}
  },
  "relationships": {
     "item": { "data": { "type": "items", "id": "urn:adsk.wipprod:dm.lineage:8jehs1iSQGu_wXpZ977bjA" } },
     "storage": { "data": { "type": "objects", "id": "urn:adsk.objects:os.object:wip.dm.prod/a7fde689-62cf-49c1-9273-8df976568996.rvt" } }
  }
 }
}

The only difference I can think of is your objectId is not correct. Image below is proof of both versions uploaded with the API.
