因為這個小範例不需要任何 `await` 陳述式，我們加入 `await anyio.sleep(0)`，讓事件迴圈有機會處理取消。

對於大型或無限的串流來說，這點更為重要。

/// tip

與其直接回傳 `StreamingResponse`，你大概會想遵循[資料串流](./stream-data.md)中的作法，這樣更方便，並且會在底層幫你處理取消。

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：

type PeerResourceMetrics struct {
	Metrics map[MetricSubsystem]ResourceMetrics
	Errors  []string
}

// ResourceMetrics is a map of unique key identifying
// a resource metric (e.g. reads_per_sec_{node}_{drive})
// to its data
type ResourceMetrics map[string]ResourceMetric

// ResourceMetric represents a single resource metric
// The metrics are collected from all servers periodically
// and stored in the resource metrics map.

   * multimap's key and value orderings correspond to the iteration ordering of the {@code
   * multimap.asMap()} view.
   *
   * <p>Despite the method name, this method attempts to avoid actually copying the data when it is
   * safe to do so. The exact circumstances under which a copy will or will not be performed are
   * undocumented and subject to change.
   *

            // Verify file ID
            assertArrayEquals(testFileId, Arrays.copyOfRange(buffer, 8, 24));

            // Verify total bytes written (structure + lock data)
            assertEquals(24 + 24, bytesWritten); // 24 for structure, 24 for lock
        }

        @Test
        @DisplayName("Should write request structure correctly with multiple locks")

「模式」是对事物的一种定义或描述。它并非具体的实现代码，而只是抽象的描述。

#### API「模式」 { #api-schema }

在这种场景下，[OpenAPI](https://github.com/OAI/OpenAPI-Specification) 是一种规定如何定义 API 模式的规范。

「模式」的定义包括你的 API 路径，以及它们可能使用的参数等等。

#### 数据「模式」 { #data-schema }

「模式」这个术语也可能指的是某些数据比如 JSON 的结构。

在这种情况下，它可以表示 JSON 的属性及其具有的数据类型，等等。

#### OpenAPI 和 JSON Schema { #openapi-and-json-schema }

#### Veri "şeması" { #data-schema }

"Şema" terimi, JSON içeriği gibi bazı verilerin şeklini de ifade edebilir.

Bu durumda, JSON attribute'ları ve sahip oldukları veri türleri vb. anlamına gelir.
