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

func (er *erasureObjects) saveMetaCacheStream(ctx context.Context, mc *metaCacheRPC, entries <-chan metaCacheEntry) (err error) {
	o := mc.o
	o.debugf(color.Green("saveMetaCacheStream:")+" with options: %#v", o)

	metaMu := &mc.mu
	rpc := mc.rpc
	cancel := mc.cancel
	defer func() {
		o.debugln(color.Green("saveMetaCacheStream:")+"err:", err)
		if err != nil && !errors.Is(err, io.EOF) {
			go mc.setErr(err.Error())
			cancel()
		}

```bash
# Imprimir uma saudação ao universo

```

...e um exemplo de código de console...

```console

`--forwarded-allow-ips="*"`로 설정하면 들어오는 모든 IP를 신뢰합니다.

**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)

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

예를 들어, *경로 처리* `/items/`를 정의했다고 해봅시다:

import java.io.FilterInputStream;

Далі ви можете вимкнути OpenAPI (включно з інтерфейсами документації), встановивши змінну оточення `OPENAPI_URL` у пусту строку, наприклад:

<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>

```bash
# Print a greeting to the universe
echo "Hello universe"
```

...and a console code example...

```console
$ <font color="#4E9A06">fastapi</font> run <u style="text-decoration-style:solid">main.py</u>
<span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting server
        Searching for package file structure
```

...and another console code example...

```console
