Validate multi value query parameter

[pzienowicz]

Hi,

Since v2.11.0 there are some changes in handling array params.
My question is how to validate multi query parameters separated by comma?

Example: /users?userId=1,2,3

After your changes in https://bitbucket.org/atlassian/swagger-request-validator/pull-requests/177 multi value is set only for style = form and explode = true which means that array separator is set to null by default.

Swagger documentation says that it could be possible by setting style = form and explode = false but it is not covered in implementation: https://swagger.io/docs/specification/serialization/

Any reason? Ideas how to solve it?

Thanks.

@jnavin is this library still supported? Is there any sense to create MR and expect it to be merged?

The library is supported, yes. I was recently on extended leave (hence the delay in replying) and can only allocate ~1 week per quarter to do active development. Having said that I am always happy to review PRs and discuss approaches to solving problems.

I just looked at your original issue description in more detail.

From my understanding of what you are asking you should be able to use a type:array with style:simple to achieve the comma-separated validation (see https://swagger.io/specification/#parameter-object). We have coverage of the array param validation in https://bitbucket.org/atlassian/swagger-request-validator/src/master/swagger-request-validator-core/src/test/java/com/atlassian/oai/validator/OpenAPIV3RequestArrayParamValidationTest.java.

Please let me know if I have misunderstood the problem (feel free to re-open if so).

Thanks.
