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

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

{* ../../docs_src/behind_a_proxy/tutorial001_01_py39.py hl[6] *}

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

        });
        return redirectWith(getClass(), moreUrl("list/1").params("dictId", form.dictId));
    }

    /**
     * Delete a stemmer override item from the dictionary.
     * Removes the specified item and redirects to the list page.
     *
     * @param form The edit form containing the item ID to delete
     * @return HTML response redirecting to the list page on success
     */

    @Secured({ ROLE })

$ 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_py39.py hl[6] *}

    )
    assertThat(eventRecorder.findEvent<FollowUpDecision>()).all {
      prop(FollowUpDecision::nextRequest).isNotNull()
    }
  }

  /**
   * Auth requires follow-ups. Unlike redirects, the auth follow-up also has a request body. This
   * test makes a single call with two duplex requests!
   */
  @Test
  fun duplexWithAuthChallenge() {
    enableProtocol(Protocol.HTTP_2)

    /**
     * Constructs a new HtmlTransformer.
     */
    public HtmlTransformer() {
        // Default constructor
    }

    /** Header name for location redirects. */
    protected static final String LOCATION_HEADER = "Location";

    /** The crawler container for dependency injection. */
    @Resource
    protected CrawlerContainer crawlerContainer;

```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>

### Weiterleitungen mit HTTPS { #redirects-with-https }

Angenommen, Sie definieren eine *Pfadoperation* `/items/`:

{* ../../docs_src/behind_a_proxy/tutorial001_01_py39.py hl[6] *}

  @Test
  fun response308WithPost() {
    testRedirect(false, "POST")
  }

  /**
   * In OkHttp 4.5 and earlier, HTTP 307 and 308 redirects were only honored if the request method
   * was GET or HEAD.
   *
   * In OkHttp 4.6 and later, HTTP 307 and 308 redirects are honored for all request methods.
   *
   * If you're upgrading to OkHttp 4.6 and would like to retain the previous behavior, install this

次の章では、FastAPIアプリケーションをデプロイするための**具体的なレシピ**を紹介します。

しかし、今はこれらの重要な**コンセプトに基づくアイデア**を確認しましょう。これらのコンセプトは、他のどのタイプのWeb APIにも当てはまります。💡

## セキュリティ - HTTPS

<!-- NOTE: https.md written in Japanese does not exist, so it redirects to English one  -->
[前チャプターのHTTPSについて](https.md){.internal-link target=_blank}では、HTTPSがどのようにAPIを暗号化するのかについて学びました。

通常、アプリケーションサーバにとって**外部の**コンポーネントである**TLS Termination Proxy**によって提供されることが一般的です。このプロキシは通信の暗号化を担当します。

		// for i, c := range via {
		// 	fmt.Printf("Sofar %d: %s %s\n", i, c.Method, c.URL.String())
		// }
		// Save the last request in a redirect chain.
		lastReq = req
		// We do not follow redirect back to client application.
		if req.URL.Path == "/oauth_callback" {
			return http.ErrUseLastResponse
		}
		return nil
	}

	dexClient := http.Client{
