## Versions disponibles

Vous pouvez consulter les versions disponibles (par exemple, pour vérifier quelle est la dernière version en date) dans les [Notes de version](../release-notes.md){.internal-link target=_blank}.

## À propos des versions

Suivant les conventions de versionnage sémantique, toute version inférieure à `1.0.0` peut potentiellement ajouter
des changements non rétrocompatibles.

    请记住可以 <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">用'X-' 前缀</a>添加专有自定义请求头.

    但是如果你想让浏览器中的客户端看到你的自定义请求头, 你需要把它们加到 CORS 配置 ([CORS (Cross-Origin Resource Sharing)](cors.md){.internal-link target=_blank}) 的 `expose_headers` 参数中,在 <a href="https://www.starlette.io/middleware/#corsmiddleware" class="external-link" target="_blank">Starlette's CORS docs</a>文档中.

!!! note "技术细节"

Si necesitas un repaso de 2 minutos de cómo usar los tipos de Python (así no uses FastAPI) prueba el tutorial corto: [Python Types](python-types.md){.internal-link target=_blank}.

Escribes Python estándar con tipos así:

```Python
from datetime import date

from pydantic import BaseModel

# Declaras la variable como un str

# Templating – `Jinja2Templates`

Sie können die `Jinja2Templates`-Klasse verwenden, um Jinja-Templates zu rendern.

Lesen Sie mehr darüber in der [FastAPI-Dokumentation zu Templates](../advanced/templates.md).

Sie können die Klasse direkt von `fastapi.templating` importieren:

```python
from fastapi.templating import Jinja2Templates
```

!!! tip
    If you want to call `async` functions in your tests apart from sending requests to your FastAPI application (e.g. asynchronous database functions), have a look at the [Async Tests](../advanced/async-tests.md){.internal-link target=_blank} in the advanced tutorial.

## Separating tests

In a real application, you probably would have your tests in a different file.

# Advanced Middleware

In the main tutorial you read how to add [Custom Middleware](../tutorial/middleware.md){.internal-link target=_blank} to your application.

And then you also read how to handle [CORS with the `CORSMiddleware`](../tutorial/cors.md){.internal-link target=_blank}.

In this section we'll see how to use other middlewares.
