이제 FastAPI는 다음을 수행합니다:

* 최대 길이가 50자인지 확인하도록 데이터를 **검증**합니다
* 데이터가 유효하지 않을 때 클라이언트에게 **명확한 오류**를 보여줍니다
* OpenAPI 스키마 *경로 처리*에 매개변수를 **문서화**합니다(따라서 **자동 문서 UI**에 표시됩니다)

## 대안(이전 방식): 기본값으로 `Query` 사용 { #alternative-old-query-as-the-default-value }

이전 FastAPI 버전(<dfn title="2023-03 이전">0.95.0</dfn> 이전)에서는 `Annotated`에 넣는 대신, 매개변수의 기본값으로 `Query`를 사용해야 했습니다. 주변에서 이 방식을 사용하는 코드를 볼 가능성이 높기 때문에 설명해 드리겠습니다.

/// tip | 팁

 *       be overridden.
 * </ul>
 *
 * <h3>Example</h3>
 *
 * {@snippet :
 * return Converter.from(
 *     Integer::toHexString,
 *     s -> parseUnsignedInt(s, 16));
 * }
 *
 * <p>An alternative using a subclass:
 *
 * {@snippet :
 * return new Converter<Integer, String>() {
 *   @Override
 *   protected String doForward(Integer i) {
 *     return Integer.toHexString(i);

FastAPI 现在会：

- 对数据进行**校验**，确保最大长度为 50 个字符
- 当数据无效时向客户端展示**清晰的错误**
- 在 OpenAPI 模式的*路径操作*中**记录**该参数（因此会出现在**自动文档 UI** 中）

## 另一种（旧的）方式：把 `Query` 作为默认值 { #alternative-old-query-as-the-default-value }

早期版本的 FastAPI（<dfn title="早于 2023-03">0.95.0</dfn> 之前）要求你把 `Query` 作为参数的默认值，而不是放在 `Annotated` 里。你很可能会在别处看到这种写法，所以我也给你解释一下。

    inappropriate.

 *  New: `HttpUrl.get(String)` is an alternative to `HttpUrl.parse(String)` that throws an exception
    when the URL is malformed instead of returning null. Use this to avoid checking for null in
    situations where the input is known to be well-formed. We've also added `MediaType.get(String)`
    which is an exception-throwing alternative to `MediaType.parse(String)`.

### [Requests](https://requests.readthedocs.io) { #requests }

**FastAPI** n'est pas réellement une alternative à **Requests**. Leur cadre est très différent.

Il serait en fait plus courant d'utiliser Requests _à l'intérieur_ d'une application FastAPI.

Mais quand même, FastAPI s'est inspiré de Requests.

	// Second, if ContentErr==nil, the content should match Content.
	// If content is large, an alternative to setting Content is to set File,
	// which names a file in the testdata/ directory containing the
	// uncompressed expected content.
	// If content is very large, an alternative to setting Content or File
	// is to set Size, which will then be checked against the header-reported size
