    * String (`str`) fields, defining min and max lengths.
    * Numbers (`int`, `float`) with min and max values, etc.

* Validation for more exotic types, like:
    * URL.
    * Email.
    * UUID.
    * ...and others.

All the validation is handled by the well-established and robust **Pydantic**.

### Security and authentication

    * campos String (`str`), definindo tamanho mínimo e máximo.
    * Numbers (`int`, `float`) com valores mínimos e máximos, etc.

* Validação de tipos mais exóticos, como:
    * URL.
    * Email.
    * UUID.
    * ...e outros.

Toda a validação é controlada pelo robusto e bem estabelecido **Pydantic**.

### Segurança e autenticação

    * Champs String (`str`), définition de longueur minimum ou maximale.
    * Nombres (`int`, `float`) avec valeur minimale and maximale, etc.

* Validation pour des types plus exotiques, tel que:
    * URL.
    * Email.
    * UUID.
    * ...et autres.

Toutes les validations sont gérées par le bien établi et robuste **Pydantic**.

### Sécurité et authentification

* 校验大部分（甚至所有？）的 Python **数据类型**，包括：
    * JSON 对象 (`dict`).
    * JSON 数组 (`list`) 定义成员类型。
    * 字符串 (`str`) 字段, 定义最小或最大长度。
    * 数字 (`int`, `float`) 有最大值和最小值， 等等。

* 校验外来类型， 比如:
    * URL.
    * Email.
    * UUID.
    * ...及其他.

所有的校验都由完善且强大的 **Pydantic** 处理。

### 安全性及身份验证

集成了安全性和身份认证。杜绝数据库或者数据模型的渗透风险。

OpenAPI 中定义的安全模式，包括：

* HTTP 基本认证。

    注意，代码中没有明文密码**`secret`**，只保存了它的哈希值。

调用 `/users/me/` 端点，收到下面的响应：

```JSON
{
  "username": "johndoe",
  "email": "******@****.***",
  "full_name": "John Doe",
  "disabled": false
}
```

Keep in mind that this means that the whole contents will be stored in memory. This will work well for small files.

But there are several cases in which you might benefit from using `UploadFile`.

## File Parameters with `UploadFile`

Define a file parameter with a type of `UploadFile`:

=== "Python 3.9+"

There you can select "Releases only".

By doing it, you will receive notifications (in your email) whenever there's a new release (a new version) of **FastAPI** with bug fixes and new features.

## Connect with the author

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

Ou mais exatamente, usando `user_dict` diretamente, com qualquer conteúdo que ele possa ter no futuro:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
)
```

🔜 🏁 🕳 🌓:

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

⚖️ 🌅 ⚫️❔, ⚙️ `user_dict` 🔗, ⏮️ ⚫️❔ 🎚 ⚫️ 💪 ✔️ 🔮:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
)
```
