Now `fastapi` doesn't include those standard dependencies unless you install with `pip install "fastapi[standard]"`.

Before, you would install `pip install fastapi`, now you should include the `standard` optional dependencies (unless you want to exclude one of those): `pip install "fastapi[standard]"`.

# 파일 요청

`File`을 사용하여 클라이언트가 업로드할 파일들을 정의할 수 있습니다.

/// info | 정보

업로드된 파일을 전달받기 위해 먼저 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>를 설치해야합니다.

예시) `pip install python-multipart`.

업로드된 파일들은 "폼 데이터"의 형태로 전송되기 때문에 이 작업이 필요합니다.

///

## `File` 임포트

`fastapi` 에서 `File` 과 `UploadFile` 을 임포트 합니다:

{* ../../docs_src/request_files/tutorial001.py hl[1] *}

val Project.gradleInstallPath: Provider<String>
    get() = gradleProperty(GRADLE_INSTALL_PATH).orElse(
        provider<String> {
            throw RuntimeException("You can't install without setting the $GRADLE_INSTALL_PATH property.")
        }
    )


val Project.rerunAllTests: Provider<Boolean>
    get() = gradleProperty(RERUN_ALL_TESTS).map { true }.orElse(false)

Antes do FastAPI 0.106.0, lançar exceções após o `yield` não era possível, o código de saída em dependências com `yield` era executado depois que a resposta era enviada, então [Tratadores de Exceções](../tutorial/handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank} já teriam sido executados.

    `NullPointerException: bio == null`.


## Version 4.9.0

_2020-09-11_

**With this release, `okhttp-tls` no longer depends on Bouncy Castle and doesn't install the
Bouncy Castle security provider.** If you still need it, you can do it yourself:

```
Security.addProvider(BouncyCastleProvider())
```

You will also need to configure this dependency:

```

See for example section `### Quotes` in `docs/de/llm-prompt.md`.

## Quotes in code snippets { #quotes-in-code-snippets }

//// tab | Test

`pip install "foo[bar]"`

Examples for string literals in code snippets: `"this"`, `'that'`.

A difficult example for string literals in code snippets: `f"I like {'oranges' if orange else "apples"}"`

OpenAPI中所包含的模型里有相同的信息可以用于 **生成客户端代码**。

### 生成一个TypeScript 客户端

现在我们有了带有模型的应用，我们可以为前端生成客户端代码。

#### 安装 `openapi-ts`

您可以使用以下工具在前端代码中安装 `openapi-ts`:

<div class="termy">

```console
$ npm install @hey-api/openapi-ts --save-dev

---> 100%
```

</div>

#### 生成客户端代码

要生成客户端代码，您可以使用现在将要安装的命令行应用程序 `openapi-ts`。

因为它安装在本地项目中，所以您可能无法直接使用此命令，但您可以将其放在 `package.json` 文件中。

它可能看起来是这样的:

{* ../../docs_src/dependencies/tutorial008b_an_py39.py hl[18:22,31] *}

Если вы хотите перехватывать исключения и формировать на их основе пользовательский ответ, создайте [Пользовательский обработчик исключений](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank}.

## Зависимости с `yield` и `except` { #dependencies-with-yield-and-except }

これを行うには、`return`の代わりに`yield`を使い、その後に追加のステップを書きます。

/// tip | 豆知識

`yield`は必ず一度だけ使用するようにしてください。

/// info | 情報

これを動作させるには、**Python 3.7** 以上を使用するか、**Python 3.6** では"backports"をインストールする必要があります:

```
pip install async-exit-stack async-generator
```

Wenn Sie Exceptions abfangen und darauf basierend eine benutzerdefinierte Response erstellen möchten, erstellen Sie einen [benutzerdefinierten Exceptionhandler](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank}.
