Handling Field Matching and Validation for application/x-www-form-urlencoded in Huma

[learning-go123]

Refer to this: #285
I wrote the following code

var DefaultFormPostFormat = huma.Format{
	Marshal: nil,
	Unmarshal: func(data []byte, v any) error {
		params, err := url.ParseQuery(string(data))
		if err != nil {
			return err
		}
		if vPtr, ok := v.(*interface{}); ok {
			m := map[string]any{}
			for k := range params {
				m[snakeToCamel(k)] = params.Get(k)
			}
			*vPtr = m
			return nil
		}
		return mapForm(v, params)
	},
}

config.Formats["application/x-www-form-urlencoded"] = DefaultFormPostFormat

There is a problem here. If the fields of params are more than the fields of the structure in v, it will not pass the validation. Turning off validation will introduce additional validators. Is there some better way to make the code more unified?

@learning-go123 sorry I don't entirely understand the question. Do you have a runnable example or some input example vs. input struct where this fails and what you would prefer to see happen?
