如果你要串流 JSON Lines，請參考教學：[串流 JSON Lines](../tutorial/stream-json-lines.md)。

///

### `FileResponse` { #fileresponse }

以非同步串流方式將檔案作為回應。

它在初始化時所需的參數與其他回應型別不同：

- `path` - 要串流的檔案路徑。
- `headers` - 要包含的自訂標頭，字典形式。
- `media_type` - 描述 media type 的字串。若未設定，將根據檔名或路徑推斷 media type。
- `filename` - 若設定，會包含在回應的 `Content-Disposition` 中。

檔案回應會包含適當的 `Content-Length`、`Last-Modified` 與 `ETag` 標頭。

    a `Content-Length`.
 *  Fix: Don't crash if the thread is interrupted while reading the public
    suffix database.
 *  Fix: Use relative resource path when loading the public suffix database.
    Loading the resource using a path relative to the class prevents conflicts
    when the OkHttp classes are relocated (shaded) by allowing multiple private
    copies of the database.

`@lru_cache` については後で説明します。

今は `get_settings()` が普通の関数だと考えてください。

そして、*path operation 関数*から依存関係として要求し、必要な場所でどこでも使えます。

### 設定とテスト { #settings-and-testing }

Kullanımı çok basittir. Örneğin bir `GET` isteği yapmak için:

```Python
response = requests.get("http://example.com/some/url")
```

Buna karşılık bir FastAPI API *path operation*’ı şöyle olabilir:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

`requests.get(...)` ile `@app.get(...)` arasındaki benzerliklere bakın.

		// Case with proper components
		{
			bucketName: bucketName,
			objectName: "etc/path/proper/.../etc",
			byteRange:  "",
			accessKey:  credentials.AccessKey,
			secretKey:  credentials.SecretKey,

			expectedContent: encodeResponse(getAPIErrorResponse(ctx,
				getAPIError(ErrNoSuchKey),
				getGetObjectURL("", bucketName, "etc/path/proper/.../etc"),
				"", "")),
			expectedRespStatus: http.StatusNotFound,
		},
	}

            @Override
            public boolean isSecure() {
                return false;
            }

            @Override
            public jakarta.servlet.RequestDispatcher getRequestDispatcher(String path) {
                return null;
            }

            @Override
            public int getRemotePort() {
                return 0;
            }

            @Override

		return
	}

	// Read escaped copy source path to check for parameters.
	cpSrcPath := r.Header.Get(xhttp.AmzCopySource)
	var vid string
	if u, err := url.Parse(cpSrcPath); err == nil {
		vid = strings.TrimSpace(u.Query().Get(xhttp.VersionID))
		// Note that url.Parse does the unescaping
		cpSrcPath = u.Path
	}

	srcBucket, srcObject := path2BucketObject(cpSrcPath)

/// tip | Tipp

Hier verwenden wir `Query()`, weil dies ein **Query-Parameter** ist. Später werden wir andere wie `Path()`, `Body()`, `Header()`, und `Cookie()` sehen, die auch dieselben Argumente wie `Query()` akzeptieren.

FastAPI wird nun:

* Die Daten **validieren**, um sicherzustellen, dass die Länge maximal 50 Zeichen beträgt

받은 토큰을 디코딩하고 검증한 뒤 현재 사용자를 반환합니다.

토큰이 유효하지 않다면 즉시 HTTP 오류를 반환합니다.

## `/token` *경로 처리* 업데이트 { #update-the-token-path-operation }

토큰의 만료 시간으로 `timedelta`를 생성합니다.

실제 JWT 액세스 토큰을 생성하여 반환합니다.
