Und dann können sie es noch einmal versuchen, wohl wissend, dass es wahrscheinlich eher etwas mit `stanleyjobsox` als mit `johndoe` zu tun hat.

#### Ein „professioneller“ Angriff

And then they can try again knowing that it's probably something more similar to `stanleyjobsox` than to `johndoe`.

#### A "professional" attack

Of course, the attackers would not try all this by hand, they would write a program to do it, possibly with thousands or millions of tests per second. And would get just one extra correct letter at a time.

## Number validations: floats, greater than and less than

Number validations also work for `float` values.

Here's where it becomes important to be able to declare <abbr title="greater than"><code>gt</code></abbr> and not just <abbr title="greater than or equal"><code>ge</code></abbr>. As with it you can require, for example, that a value must be greater than `0`, even if it is less than `1`.

また、数値のバリデーションを宣言することもできます:

* `gt`: より大きい（`g`reater `t`han）
* `ge`: 以上（`g`reater than or `e`qual）
* `lt`: より小さい（`l`ess `t`han）
* `le`: 以下（`l`ess than or `e`qual）

!!! info "情報"
    `Query`、`Path`などは後に共通の`Param`クラスのサブクラスを見ることになります。（使う必要はありません）

    そして、それらすべては、これまで見てきた追加のバリデーションとメタデータと同じパラメータを共有しています。

!!! note "技術詳細"

而且你还可以声明数值校验：

* `gt`：大于（`g`reater `t`han）
* `ge`：大于等于（`g`reater than or `e`qual）
* `lt`：小于（`l`ess `t`han）
* `le`：小于等于（`l`ess than or `e`qual）

!!! info
    `Query`、`Path` 以及你后面会看到的其他类继承自一个共同的 `Param` 类（不需要直接使用它）。

    而且它们都共享相同的所有你已看到并用于添加额外校验和元数据的参数。

!!! note "技术细节"
    当你从 `fastapi` 导入 `Query`、`Path` 和其他同类对象时，它们实际上是函数。

    当被调用时，它们返回同名类的实例。

    如此，你导入 `Query` 这个函数。当你调用它时，它将返回一个同样命名为 `Query` 的类的实例。

        That's a lot of work they are doing, but if more FastAPI users came to help others like them just a little bit more, it would be much less effort for them (and you and me 😅).

        By asking questions in a structured way (following this) it will be much easier to help you.

E você também pode declarar validações numéricas:

* `gt`: maior que (`g`reater `t`han)
* `ge`: maior que ou igual (`g`reater than or `e`qual)
* `lt`: menor que (`l`ess `t`han)
* `le`: menor que ou igual (`l`ess than or `e`qual)

!!! info "Informação"
    `Query`, `Path` e outras classes que você verá a frente são subclasses de uma classe comum `Param`.

!!! note
    `PATCH` is less commonly used and known than `PUT`.

    And many teams use only `PUT`, even for partial updates.

    You are **free** to use them however you want, **FastAPI** doesn't impose any restrictions.

    But this guide shows you, more or less, how they are intended to be used.

### Using Pydantic's `exclude_unset` parameter

✋️ ⚫️ 🚫 ✔️ `id` 🏑.

👥 ✍ 🆕 `dict`, 👈 🔌 🔑-💲 👫 ⚪️➡️ `note.dict()` ⏮️:

```Python
{**note.dict()}
```

`**note.dict()` "unpacks" the key value pairs directly, so, `{**note.dict()}` would be, more or less, a copy of `note.dict()`.

& ⤴️, 👥 ↔ 👈 📁 `dict`, ❎ ➕1️⃣ 🔑-💲 👫: `"id": last_record_id`:

```Python
{**note.dict(), "id": last_record_id}
```

, 🏁 🏁 📨 🔜 🕳 💖:

```Python

그리고 숫자 검증 또한 선언할 수 있습니다:

* `gt`: 크거나(`g`reater `t`han)
* `ge`: 크거나 같은(`g`reater than or `e`qual)
* `lt`: 작거나(`l`ess `t`han)
* `le`: 작거나 같은(`l`ess than or `e`qual)

!!! info "정보"
    `Query`, `Path`, 그리고 나중에게 보게될 것들은 (여러분이 사용할 필요가 없는) 공통 `Param` 클래스의 서브 클래스입니다.

    그리고 이들 모두는 여태까지 본 추가 검증과 메타데이터의 동일한 모든 매개변수를 공유합니다.
