## FastAPI 专家 - 上个月

It is a project from the Linux Foundation. It provides **HTTPS certificates for free**, in an automated way. These certificates use all the standard cryptographic security, and are short-lived (about 3 months), so the **security is actually better** because of their reduced lifespan.

The domains are securely verified and the certificates are generated automatically. This also allows automating the renewal of these certificates.

# 包含 WSGI - Flask，Django，其它

您可以挂载多个 WSGI 应用，正如您在 [Sub Applications - Mounts](sub-applications.md){.internal-link target=_blank}, [Behind a Proxy](behind-a-proxy.md){.internal-link target=_blank} 中所看到的那样。

为此, 您可以使用 `WSGIMiddleware` 来包装你的 WSGI 应用，如：Flask，Django，等等。

## 使用 `WSGIMiddleware`

您需要导入 `WSGIMiddleware`。

然后使用该中间件包装 WSGI 应用（例如 Flask）。

之后将其挂载到某一个路径下。

```Python hl_lines="2-3  22"
{!../../../docs_src/wsgi/tutorial001.py!}
```

                    <mxGeometry x="-140" y="-75" width="500" height="350" as="geometry"/>
                </mxCell>
                <mxCell id="29" value="&lt;font face=&quot;Roboto&quot; data-font-src=&quot;https://fonts.googleapis.com/css?family=Roboto&quot; style=&quot;font-size: 24px&quot;&gt;https://someapp.example.com&lt;/font&gt;" style="rounded=0;whiteSpace=wrap;html=1;fontStyle=1;strokeWidth=4;" parent="33" vertex="1">

{% if people %}
<div class="user-list user-list-center">
{% for user in people.last_month_experts[:10] %}

{% if people %}
<div class="user-list user-list-center">
{% for user in people.last_month_experts[:10] %}

{!../../../docs_src/behind_a_proxy/tutorial004.py!}
```

and then it won't include it in the OpenAPI schema.

## Mounting a sub-application

If you need to mount a sub-application (as described in [Sub Applications - Mounts](sub-applications.md){.internal-link target=_blank}) while also using a proxy with `root_path`, you can do it normally, as you would expect.

For example, it was clear that ideally it should be based on standard Python type hints.

Also, the best approach was to use already existing standards.

So, before even starting to code **FastAPI**, I spent several months studying the specs for OpenAPI, JSON Schema, OAuth2, etc. Understanding their relationship, overlap, and differences.
