Validate parameters name in a case insensitive way

[StefanoTesla]

I need a little help to validate the presence of a parameter in an uncase sensitive way.

At the moment my schema is this one.
Everything is working fine, but my api protocol provide that the parameters validation should be case insensitive so I should accept olso clIENTid pr clientid or CLIENTID or any way to write clientid wito lower and uppercase.

How can I do? should I use an Hook and cycle over all the parameters name and converting them in lowercase?

const querySchema = { type: 'object', properties: { ClientID: { type: 'number' }, ClientTransactionID: { type: 'number' } }, required: ['ClientID', 'ClientTransactionID'] };

The RFC-3986, is kind of ambiguous as does not specifies if the key of the key=value pairs should be case sensitive or not, so it is up to each implementation to decide how to handle it.

You can use the patternProperties feature from ajv to construct a regex that covers both cases of your properties (i.e. either clientid or clientId, etc.).

Another option is to use the preValidation hook to intercept the request before validation and parse your query object to a lower (or upper) case version of it.
