Hey Niraj,

That does seem to be incorrect behavior on the services side. It would be good to have a bug filed to track it. For now you could open one and flag each project as being affected. We may find that it requires a change in each project, or it may end up being a common oslo change. Either way, a bug will allow us to capture findings and make sure it gets resolved.

Thanks,

Hi Devs,

As of now, when user passes 'Accept' header in request other than JSON and XML using curl command then it returns 200 OK response with json format data.

In api-ref guide [1] also it's not clearly mentioned about what response it should return if invalid value for 'Accept' header is specified. IMO instead of 'HTTP 200 OK' it should return 'HTTP 406 Not Acceptable' response.

I have checked this behavior for nova, cinder and glance and for all of these it is returning HTTP 200 OK which is invalid.

Please let me know your opinion for the same.

Steps to reproduce:

Request:

curl -g -i -X GET http://controller/volume/v2/c72e66cc4f1341f381e0c2eb7b28b443/volumes/detail -H "User-Agent: python-cinderclient" -H "Accept: application/abc" -H "X-Auth-Token: cd85aff745ce4dc0a04f686b52cf7e4f"

Response:

HTTP/1.1 200 OK
