```python
def say_hi(name: str | None):
    print(f"Hey {name}!")
```

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

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

</div>

После этого, если перейти по адресам `/openapi.json`, `/docs` или `/redoc`, вы получите ошибку `404 Not Found`, например:

### Otomatik API dokümanlarını kontrol edin { #check-the-automatic-api-docs }

Şimdi `fastapi` komutunu çalıştırın:

<div class="termy">

```console
$ fastapi dev

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

</div>

Ve dokümanları [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs) adresinden açın.

如果设置为 `--forwarded-allow-ips="*"`，就会信任所有来源 IP。

如果你的**服务器**位于受信任的**代理**之后，并且只有代理会与它通信，这将使其接受该**代理**的任何 IP。

<div class="termy">

```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>

### 使用 HTTPS 的重定向 { #redirects-with-https }

例如，假设你定义了一个*路径操作* `/items/`：

<div class="termy">

```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/`:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

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

</div>

Luego, si vas a las URLs en `/openapi.json`, `/docs`, o `/redoc`, solo obtendrás un error `404 Not Found` como:

```JSON

### Проверьте автоматическую документацию API { #check-the-automatic-api-docs }

Теперь запустите команду `fastapi`:

<div class="termy">

```console
$ fastapi dev

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

</div>

И откройте документацию по адресу [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

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

</div>

Então, se você acessar as URLs em `/openapi.json`, `/docs` ou `/redoc`, você receberá apenas um erro `404 Not Found` como:

**서버**가 신뢰할 수 있는 **프록시** 뒤에 있고 프록시만 서버에 접근한다면, 이는 해당 **프록시**의 IP가 무엇이든 간에 받아들이게 됩니다.

<div class="termy">

```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>

### HTTPS에서 리디렉션 { #redirects-with-https }

예를 들어, *경로 처리* `/items/`를 정의했다고 해봅시다:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

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

</div>

Потім, якщо ви перейдете за URL `/openapi.json`, `/docs` або `/redoc`, ви просто отримаєте помилку `404 Not Found` на кшталт:
