## Sobre "Campos de formulário"

A forma como os formulários HTML (`<form></form>`) enviam os dados para o servidor normalmente usa uma codificação "especial" para esses dados, é diferente do JSON.

O **FastAPI** fará a leitura desses dados no lugar certo em vez de JSON.

                    "type": "missing",

```JSON
{
  "item": "The Foo Wrestlers"
}
```

But if the client requests `http://example.com/items/bar` (a non-existent `item_id` `"bar"`), that client will receive an HTTP status code of 404 (the "not found" error), and a JSON response of:

```JSON
{
  "detail": "Item not found"
}
```
