`Form` sınıfıyla tanımlama yaparken `Body`, `Query`, `Path` ve `Cookie` sınıflarında kullandığınız aynı validasyon, örnekler, isimlendirme (örneğin `username` yerine `user-name` kullanımı) ve daha fazla konfigurasyonu kullanabilirsiniz.

/// info | Bilgi

`Form` doğrudan `Body` sınıfını miras alan bir sınıftır.
