* An optional query parameter `skip` that is an `int`, and by default is `0`.
* An optional query parameter `limit` that is an `int`, and by default is `100`.

And then it just returns a `dict` containing those values.

/// info

FastAPI added support for `Annotated` (and started recommending it) in version 0.95.0.

If you have an older version, you would get errors when trying to use `Annotated`.

Но, по умолчанию, всё это **"и так работает"**.

### Проверка значений

* Проверка значений для большинства (или всех?) **типов данных**  Python, включая:
    * Объекты JSON (`dict`).
    * Массивы JSON (`list`) с установленными типами элементов.
    * Строковые (`str`) поля с ограничением минимальной и максимальной длины.
    * Числа (`int`, `float`) с минимальными и максимальными значениями и т.п.

### Template Context Values

In the HTML that contains:

{% raw %}

```jinja
Item ID: {{ id }}
```

{% endraw %}

...it will show the `id` taken from the "context" `dict` you passed:

```Python
{"id": id}
```

For example, with an ID of `42`, this would render:

```html
Item ID: 42
```

### Template `url_for` Arguments

    user = get_user(fake_db, username)
    if not user:
        return False
    if not verify_password(password, user.hashed_password):
        return False
    return user

        expire = datetime.now(timezone.utc) + expires_delta

# 响应Cookies

## 使用 `Response` 参数

你可以在 *路径函数* 中定义一个类型为 `Response`的参数，这样你就可以在这个临时响应对象中设置cookie了。

```Python hl_lines="1  8-9"
{!../../docs_src/response_cookies/tutorial002.py!}
```

而且你还可以根据你的需要响应不同的对象，比如常用的 `dict`，数据库model等。

如果你定义了 `response_model`，程序会自动根据`response_model`来过滤和转换你响应的对象。

**FastAPI** 会使用这个 *临时* 响应对象去装在这些cookies信息 (同样还有headers和状态码等信息), 最终会将这些信息和通过`response_model`转化过的数据合并到最终的响应里。

    user = get_user(fake_db, username)
    if not user:
        return False
    if not verify_password(password, user.hashed_password):
        return False
    return user


def create_access_token(data: dict, expires_delta: Union[timedelta, None] = None):
    to_encode = data.copy()

        expire = datetime.now(timezone.utc) + expires_delta
