/// tip

We'll discuss the `@lru_cache` in a bit.

For now you can assume `get_settings()` is a normal function.

///

And then we can require it from the *path operation function* as a dependency and use it anywhere we need it.

{* ../../docs_src/settings/app02_an_py310/main.py hl[17,19:21] *}

### Settings and testing { #settings-and-testing }

先頭は次のようになっているかもしれません:

```JavaScript
/*! For license information please see redoc.standalone.js.LICENSE.txt */
!function(e,t){"object"==typeof exports&&"object"==typeof module?module.exports=t(require("null")):
...
```

これで、アプリから静的ファイルを配信できていること、そしてドキュメント用の静的ファイルを正しい場所に配置できていることが確認できます。

次に、ドキュメントでそれらの静的ファイルを使用するようにアプリを設定します。

### 静的ファイル用に自動ドキュメントを無効化 { #disable-the-automatic-docs-for-static-files }

In this case, it requires the scope `me` (it could require more than one scope).

/// note

You don't necessarily need to add different scopes in different places.

* HAProxy

## Let's Encrypt { #lets-encrypt }

Before Let's Encrypt, these **HTTPS certificates** were sold by trusted third parties.

The process to acquire one of these certificates used to be cumbersome, require quite some paperwork and the certificates were quite expensive.

But then **[Let's Encrypt](https://letsencrypt.org/)** was created.

// access the ETag by looking for the HTTP response header key "Etag".
// However, some of them assume that the header key has to be "ETag"
// (case-sensitive) and will fail otherwise.
// Further, some clients require that the ETag value is a double-quoted
// string. Therefore, this package provides dedicated functions for
// adding and extracting the ETag to/from HTTP headers.
package etag

import (
	"bytes"
	"crypto/hmac"

        QueryBuilder result = matchAllQueryCommand.execute(context, query, boost);

        assertNotNull(result);

        // Note: Actual log output verification would require a log appender mock
        // but we can at least ensure the method executes without errors
        logger.info("Execute method called with query: {} and boost: {}", query, boost);
    }

    @Test

你应该会看到一个非常长的 **ReDoc** 的 JavaScript 文件。

它可能以如下内容开头：

```JavaScript
/*! For license information please see redoc.standalone.js.LICENSE.txt */
!function(e,t){"object"==typeof exports&&"object"==typeof module?module.exports=t(require("null")):
...
```

这就确认了你的应用能够提供静态文件，并且你把文档所需的静态文件放在了正确的位置。

现在我们可以配置应用，让文档使用这些静态文件。

### 为静态文件关闭自动文档 { #disable-the-automatic-docs-for-static-files }

和使用自定义 CDN 一样，第一步是关闭自动文档，因为默认情况下它们会使用 CDN。

It gives you all the flexibility to choose the ones that fit your project the best.

And you can use directly many well maintained and widely used packages like `pwdlib` and `PyJWT`, because **FastAPI** doesn't require any complex mechanisms to integrate external packages.

But it provides you the tools to simplify the process as much as possible without compromising flexibility, robustness, or security.

    InputStream in = newTestStream(0);
    byte[] b = ByteStreams.toByteArray(in);
    assertThat(b).isEmpty();
  }

  public void testToByteArray_largeStream() throws IOException {
    // well, large enough to require multiple buffers
    byte[] expected = newPreFilledByteArray(10000000);
    InputStream in = new ByteArrayInputStream(expected);
    byte[] b = ByteStreams.toByteArray(in);
    assertThat(b).isEqualTo(expected);
  }
