处理 `Accept-Encoding` 请求头中包含 `gzip` 请求的 GZip 响应。

中间件会处理标准响应与流响应。

```Python hl_lines="2  6"
{!../../docs_src/advanced_middleware/tutorial003.py!}
```

支持以下参数：

* `minimum_size` - 小于最小字节的响应不使用 GZip。 默认值是 `500`。

## 其它中间件

除了上述中间件外，FastAPI 还支持其它ASGI 中间件。

例如：

/// tip | 提示

如果可以，请尽量使用 `Annotated` 版本。

///

```Python hl_lines="13-14"
{!> ../../docs_src/dependencies/tutorial008c.py!}
```

////

在示例代码的情况下，客户端将会收到 *HTTP 500 Internal Server Error* 的响应，因为我们没有抛出 `HTTPException` 或者类似的异常，并且服务器也 **不会有任何日志** 或者其他提示来告诉我们错误是什么。😱

### 在包含 `yield` 和 `except` 的依赖项中一定要 `raise`

如果你在使用 `yield` 的依赖项中捕获到了一个异常，你应该再次抛出捕获到的异常，除非你抛出 `HTTPException` 或类似的其他异常，

replication_priority            (string)    set replication priority (default: 'auto')
replication_max_workers         (number)    set the maximum number of replication workers (default: '500')
transition_workers              (number)    set the number of transition workers (default: '100')
stale_uploads_expiry            (duration)  set to expire stale multipart uploads older than this values (default: '24h')

    var $moreLink = $(this),
        value = $moreLink.attr("href"),
        $info;
    if (value !== "") {
      $info = $(value + " .info");
      if ($info.length > 0) {
        $moreLink.fadeOut(500, function() {
          $info.slideDown("slow");
        });
      }
    }
    return false;
  });

  if (typeof $.fn.suggestor === "function") {
    $("#query").suggestor({
      ajaxinfo: {

                if ( retries != 1 ) {
                    // backoff, but don't delay the first attempt as there are various reasons that can be fixed
                    // immediately
                    Thread.sleep(500 + RAND.nextInt(1000));
                }
            }
            catch ( InterruptedException e ) {
                log.debug("interrupted sleep in send", e);
            }

            if ( request != null ) {

			return
		}
		t := time.NewTicker(time.Duration(pingInterval) * time.Second)
		defer t.Stop()
		emptyEventTicker = t.C
	} else {
		// Deprecated Apr 2023
		t := time.NewTicker(500 * time.Millisecond)
		defer t.Stop()
		keepAliveTicker = t.C
	}

	enc := json.NewEncoder(w)
	for {
		select {
		case ev := <-mergeCh:
			_, err := w.Write(ev)
			if err != nil {
				return

Prefer to use the `Annotated` version if possible.

///

```Python hl_lines="13-14"
{!> ../../docs_src/dependencies/tutorial008c.py!}
```

////

In this case, the client will see an *HTTP 500 Internal Server Error* response as it should, given that we are not raising an `HTTPException` or similar, but the server will **not have any logs** or any other indication of what was the error. 😱

더 쉽고 새로운 JSON 스키마와의 통합과 함께 OpenAPI 3.1.0가 배포되었지만, 잠시동안 자동 문서 생성을 제공하는 도구인 Swagger UI는 OpenAPI 3.1.0을 지원하지 않았습니다 (5.0.0 버전부터 지원합니다 🎉).

이로인해, FastAPI 0.99.0 이전 버전은 아직 OpenAPI 3.1.0 보다 낮은 버전을 사용했습니다.
