Fail on additionalProperties?

[Marclev78]

Problem statement

I want my server to reject requests where the body includes unknown properties. In json-schema I would typically do this with additional-properties=false. However according to https://goswagger.io/use/models/schemas.html go-swagger's model will simply strip such additional properties out instead of rejecting the request.

Is there anyway to instruct the generated code to fail validation if additional properties are detected, instead of ignoring them?

You can make a middleware that does that in front, but we don't support that directly, in the generated code

@Marclev78 You can try to generate your server with the --strict-additional-properties flag.
There are some corner cases with that option, but it should basically cover what you want.
