```console
$ fastapi run --forwarded-allow-ips="*"

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

### Redirections avec HTTPS { #redirects-with-https }

Par exemple, disons que vous définissez un *chemin d'accès* `/items/` :

{* ../../docs_src/behind_a_proxy/tutorial001_01_py310.py hl[6] *}

```console
$ fastapi run --forwarded-allow-ips="*"

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

### Redirecionamentos com HTTPS { #redirects-with-https }

Por exemplo, suponha que você defina uma *operação de rota* `/items/`:

{* ../../docs_src/behind_a_proxy/tutorial001_01_py310.py hl[6] *}

```console
$ fastapi run --forwarded-allow-ips="*"

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

### Редиректы с HTTPS { #redirects-with-https }

Например, вы объявили операцию пути `/items/`:

{* ../../docs_src/behind_a_proxy/tutorial001_01_py310.py hl[6] *}

Если клиент обратится к `/items`, по умолчанию произойдёт редирект на `/items/`.

```console
$ fastapi run --forwarded-allow-ips="*"

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

### Перенаправлення з HTTPS { #redirects-with-https }

Наприклад, припустимо, ви визначили *операцію шляху* `/items/`:

{* ../../docs_src/behind_a_proxy/tutorial001_01_py310.py hl[6] *}

```console
$ fastapi run --forwarded-allow-ips="*"

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

### Redirecciones con HTTPS { #redirects-with-https }

Por ejemplo, digamos que defines una *path operation* `/items/`:

{* ../../docs_src/behind_a_proxy/tutorial001_01_py310.py hl[6] *}

* kubectl: add the --no-headers flag to `kubectl top ...` ([#67890](https://github.com/kubernetes/kubernetes/pull/67890), [@WanLinghao](https://github.com/WanLinghao))
* Restrict redirect following from the apiserver to same-host redirects, and ignore redirects in some cases. ([#66516](https://github.com/kubernetes/kubernetes/pull/66516), [@tallclair](https://github.com/tallclair))

```console
$ fastapi run --forwarded-allow-ips="*"

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```
