## Про данные формы ("Form Data")

Способ, которым HTML-формы (`<form></form>`) отправляют данные на сервер, обычно использует "специальную" кодировку для этих данных, отличную от JSON.

**FastAPI** позаботится о том, чтобы считать эти данные из нужного места, а не из JSON.

    @Required
    @CustomSize(maxKey = "form.admin.max.input.size")
    public String handlerName;

    /** Parameters passed to the data handler */
    @CustomSize(maxKey = "form.admin.max.input.size")
    public String handlerParameter;

    /** Script for custom data processing logic */
    @CustomSize(maxKey = "form.admin.max.input.size")
    public String handlerScript;
