!!! tip
    SQLAlchemy 模型`User`包含一个`hashed_password`，它应该是一个包含散列的安全密码。

    但由于 API 客户端提供的是原始密码，因此您需要将其提取并在应用程序中生成散列密码。

    然后将hashed_password参数与要保存的值一起传递。

!!! warning
    此示例不安全，密码未经过哈希处理。

    在现实生活中的应用程序中，您需要对密码进行哈希处理，并且永远不要以明文形式保存它们。

    有关更多详细信息，请返回教程中的安全部分。

    在这里，我们只关注数据库的工具和机制。

    The "PATCH" is the last number, for example, in `0.2.3`, the PATCH version is `3`.

So, you should be able to pin to a version like:

```txt
fastapi>=0.45.0,<0.46.0
```

Breaking changes and new features are added in "MINOR" versions.

!!! tip
    The "MINOR" is the number in the middle, for example, in `0.2.3`, the MINOR version is `2`.

des changements rétrocompatibles.

!!! tip "Astuce"
    Le "PATCH" est le dernier chiffre, par exemple, dans `0.2.3`, la version PATCH est `3`.

Donc, vous devriez être capable d'épingler une version comme suit :

```txt
fastapi>=0.45.0,<0.46.0
```

Les changements non rétrocompatibles et les nouvelles fonctionnalités sont ajoutés dans les versions "MINOR".

!!! tip
    Notice the auto-generated server with a `url` value of `/api/v1`, taken from the `root_path`.

In the docs UI at <a href="http://127.0.0.1:9999/api/v1/docs" class="external-link" target="_blank">http://127.0.0.1:9999/api/v1/docs</a> it would look like:

!!! tip
    The docs UI will interact with the server that you select.

Projeniz için ilginç ve yararlı görünen bir şey varsa devam edin ve inceleyin, aksi halde bunları atlayabilirsiniz.

!!! tip "İpucu"

You can import it directly from `fastapi`:

```python
from fastapi import Request
```

!!! tip
    When you want to define dependencies that should be compatible with both HTTP and WebSockets, you can define a parameter that takes an `HTTPConnection` instead of a `Request` or a `WebSocket`.
