Autodesk Forge API。 如何获得特定版本的物品？

Question

I'm to get a specific version of the item from the Autodesk Forge. I use this instruction to do it. There is a template of a request:

GET projects/:project_id/versions/:version_id/item

So my request look similar (I cuted out a part for brevity):

https://developer.api.autodesk.com/data/v1/projects/a.cGV ... TU2/versions/urn:adsk.wipprod:fs.file:vf.lTvo5GGBRzidiQ8Kredbaw?version=1/item

But the request returns error 400 (Bad request).

When I just get the itemin the same way (using an intended for this template of course) all is okay.

Should I to use this template or other? What am I doing wrong?

Answer 1

The version_id should be escaped into a URL safe form since there are some reserved and unsafe keywords ( ie : , . , ? and = ) in this parameter. They will invalid your request to the Forge service. ( Ref )

For example, your version_id is urn:adsk.wipprod:fs.file:vf.d34fdsg3g?version=2 , then you have to tranform it like:

urn%3Aadsk.wipprod%3Afs.file%3Avf.b909RzMKR4mhc3O7UBY_8g%3Fversion%3D2 .

In JavaScript, the encodeURIComponent() ( Ref ) function can help you do this transformation. Here is a sample for you:

encodeURIComponent('urn:adsk.wipprod:fs.file:vf.d34fdsg3g?version=2')

If your codes are written in C#, you can call Uri.EscapeDataString() ( Ref ) to archive the same goal.
