Why do I get 401 as API response when adding query string to request url?

lebenito

I am using the client.api_client.request(method, url=url, query_params=params, headers=headers, body=payload) from the python client.

Other API get and post calls work just fine.

When I try to export an stl or get the mass properties of a part studio it works just fine until I put a query string in the request url for example the configuration,

but other query parameters also do not work. It says "message":"Unauthenticated API request", "status":401

Here is an example of a not working request url: https://cad.onshape.com/api/partstudios/d/c3c64dc4cc39570a7e58f079/w/cc1d338579f170714f7a792d/e/9266a7733c2327e4f1ab87c6/massproperties?massAsGroup=true&configuration=rad1=2inch

This works though when I put the link manually in my browser where I am logged into my Onshape account.

But my shadedView api call works with a query string. The query strings are formatted and encoded the exact same way, so I do not understand why this call works with query parameters but stl and mass properties do not.
For the stl I already got told a work around with translations, but I cant find such work around for the massproperties.

Why is that happening or is there maybe also a work around for the mass properties?

You are passing a poorly encoded string https://cad.onshape.com/api/partstudios/d/c3c64dc4cc39570a7e58f079/w/cc1d338579f170714f7a792d/e/9266a7733c2327e4f1ab87c6/massproperties?massAsGroup=true&configuration=rad1=2inch (removed the `amp;` portion and encoded the equals after the param string.)

@lougallo I actually don't know how this & came in there but it was not actually in my api call ...

My encoding works for the shaded View call and when I put it manually in my browser. But I still tried it now with this encoding:

https://cad.onshape.com/api/partstudios/d/c3c64dc4cc39570a7e58f079/w/cc1d338579f170714f7a792d/e/9266a7733c2327e4f1ab87c6/massproperties?configuration=rad1=1inch

This call also gives me back 401 but works when I put it manually in the browser, So the encoding does not seem to be the issue right?

?configuration=rad1=1inch

is not a valid query string.  Query strings need to follow the pattern <key>=<value>.  For configurations to work properly, the configuration needs to be URI encoded.

Try

?configuration=rad1%3D1inch

Hey @jakeramsley, Thank you for your answer.

Yes that is exactly what I was trying before which also does not work

My answer was reffering to @lougallo who suggested trying

?configuration=rad1=1inch

Even when I just try ?massAsGroup=true or any other correct query string it won't work.
It works just without the query string.

Shaded view works: https://cad.onshape.com/api/partstudios/d/c3c64dc4cc39570a7e58f079/w/cc1d338579f170714f7a792d/e/9266a7733c2327e4f1ab87c6/shadedviews?viewMatrix=0.612,0.612,0,0,-0.354,0.354,0.707,0,0.707,-0.707,0.707,0&amp;outputHeight=500&amp;outputWidth=800&amp;pixelSize=0&amp;includeSurfaces=true&amp;edges="hide"&amp;configuration=rad1=1.0inch

But for massProperties or stl (which I got told a work around already so is of no more worries) doesn't:

This works: https://cad.onshape.com/api/partstudios/d/c3c64dc4cc39570a7e58f079/w/cc1d338579f170714f7a792d/e/9266a7733c2327e4f1ab87c6/massproperties

This does not work (Only when I put it manually in my browser): https://cad.onshape.com/api/partstudios/d/c3c64dc4cc39570a7e58f079/w/cc1d338579f170714f7a792d/e/9266a7733c2327e4f1ab87c6/massproperties?configuration=rad1=2inch
