## Classe `APIRoute` personalizada em um router

você também pode definir o parametro `route_class` de uma `APIRouter`;

## Custom `APIRoute` class in a router { #custom-apiroute-class-in-a-router }

You can also set the `route_class` parameter of an `APIRouter`:

[entryPoints]
  [entryPoints.http]
    address = ":9999"

[providers]
  [providers.file]
    filename = "routes.toml"
```

这个文件把 Traefik 监听端口设置为 `9999`，并设置要使用另一个文件 `routes.toml`。

/// tip | 提示

使用端口 9999 代替标准的 HTTP 端口 80，这样就不必使用管理员权限运行（`sudo`）。

///

接下来，创建 `routes.toml`：

```TOML hl_lines="5  12  20"
[http]
  [http.middlewares]

[providers]
  [providers.file]
    filename = "routes.toml"
```

Dadurch wird Traefik angewiesen, Port 9999 abzuhören und eine andere Datei `routes.toml` zu verwenden.

/// tip | Tipp

Wir verwenden Port 9999 anstelle des Standard-HTTP-Ports 80, damit Sie ihn nicht mit Administratorrechten (`sudo`) ausführen müssen.

///

Erstellen Sie nun die andere Datei `routes.toml`:

```TOML hl_lines="5  12  20"
[http]

`FastAPI` est une classe Python qui fournit toutes les fonctionnalités nécessaires au lancement de votre API.

/// note | Détails techniques

`FastAPI` est une classe héritant directement de `Starlette`.

Vous pouvez donc aussi utiliser toutes les fonctionnalités de <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> depuis `FastAPI`.

[providers]
  [providers.file]
    filename = "routes.toml"
```

This tells Traefik to listen on port 9999 and to use another file `routes.toml`.

/// tip

We are using port 9999 instead of the standard HTTP port 80 so that you don't have to run it with admin (`sudo`) privileges.

///

Now create that other file `routes.toml`:

```TOML hl_lines="5  12  20"
