Query parameters with "deepObject" and the "explode" keyword

[shadowhand]

Given the following parameters schema:

{
    "name": "filter",
    "in": "query",
    "style": "deepObject",
    "explode": false,
    "schema": {
        "type": "object",
        "properties": {
            "status": {
                "type": "array",
                "items": {
                    "type": "string",
                    "enum": ["open", "pending", "needs_attention", "done"]
                }
            }
        }
    }
}

I should would expect a query string filter[status]=open,pending to be parsed as:

[
    'filter' => [
        'status' => [
            'open',
            'pending',
        ]
]

However, it seems that this package does not respect the explode: false configuration and reports that the status parameter is a string.

The implementation is clearly missing :)

I'm trying to understand the documentation regarding serialization. As far as I understand, style: deepObject requires explode: true?

Also, can you really assume that the array should be parsed using a comma as delimiter in this specific case?

I might be wrong, but reading the documentation my guess would be that parsing the query filter[status][0]=open&filter[status][1]=pending would produce the result you expected?

According to JSON-API recommendations the filter parameter should use a comma-separated list of values. We've used deepObject with explode: false in the past with other tools to follow this recommendation.
