But in case you needed it for an advanced scenario, you can add custom headers:

```Python hl_lines="14"

```

## Install custom exception handlers

You can add custom exception handlers with <a href="https://www.starlette.io/exceptions/" class="external-link" target="_blank">the same exception utilities from Starlette</a>.

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)

## 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:

```

        if (data != null) {
            try {
                return SerializeUtil.fromBinaryToObject(data);
            } catch (final Exception e) {
                throw new CrawlerSystemException("Could not create an instanced from bytes.", e);
            }
        }
        return new HashMap<String, Object>();
    }

    public void addMetaContentMapping(final String metaname, final String dynamicField) {

		includes:        append([]string{filepath.Dir(name)}, flags.I...),
		beginningOfLine: true,
		macros:          predefine(flags.D),
	}
}

// predefine installs the macros set by the -D flag on the command line.
func predefine(defines flags.MultiFlag) map[string]*Macro {
	macros := make(map[string]*Macro)
	for _, name := range defines {
		value := "1"

# 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:
