* `datetime.timedelta`:
    * 파이썬의 `datetime.timedelta`.
    * 요청과 응답에서 전체 초(seconds)의 `float`로 표현됩니다.
    * Pydantic은 "ISO 8601 시차 인코딩"으로 표현하는 것 또한 허용합니다. <a href="https://docs.pydantic.dev/latest/concepts/serialization/#json_encoders" class="external-link" target="_blank">더 많은 정보는 이 문서에서 확인하십시오.</a>.
* `frozenset`:
    * 요청과 응답에서 `set`와 동일하게 취급됩니다:
        * 요청 시, 리스트를 읽어 중복을 제거하고 `set`로 변환합니다.

### Es in der Dokumentation ansehen

Jetzt können Sie Ihre Anwendung mit Uvicorn starten und auf <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a> gehen.

Sie werden sehen, dass Ihre Dokumentation die normalen *Pfadoperationen* und jetzt auch einige **Webhooks** enthält:

	"versionId",
	"versioning",
	"versions",
	"website",
}

// Signature and API related constants.
const (
	signV2Algorithm = "AWS"
)

// AWS S3 Signature V2 calculation rule is give here:
// http://docs.aws.amazon.com/AmazonS3/latest/dev/RESTAuthentication.html#RESTAuthenticationStringToSign
func doesPolicySignatureV2Match(formValues http.Header) (auth.Credentials, APIErrorCode) {
	accessKey := formValues.Get(xhttp.AmzAccessKeyID)

	}
	return filepath.ToSlash(s) + "/"
}

// FileWithLineNum return the file name and line number of the current file
func FileWithLineNum() string {
	pcs := [13]uintptr{}

# Test Client - `TestClient`

You can use the `TestClient` class to test FastAPI applications without creating an actual HTTP and socket connection, just communicating directly with the FastAPI code.

Read more about it in the [FastAPI docs for Testing](https://fastapi.tiangolo.com/tutorial/testing/).

You can import it directly from `fastapi.testclient`:

```python
from fastapi.testclient import TestClient
```

                traverseFileSystem(rootDir, file, handler);
            } else {
                final int pos = FileUtil.getCanonicalPath(rootDir).length();
                final String filePath = FileUtil.getCanonicalPath(file);
                final String resourcePath = filePath.substring(pos + 1).replace('\\', '/');
                final InputStream is = InputStreamUtil.create(file);
                try {
