### Preferred translations / glossary

- Should avoid using simplified Chinese characters and terms. Always examine if the translation can be easily comprehended by the Traditional Chinese readers.
- For some Python-specific terms like "pickle", "list", "dict" etc, we don't have to translate them.
- Use the following preferred translations when they apply in documentation prose:

- request (HTTP): 請求

//   - SSE-KMS
type Type interface {
	fmt.Stringer

	IsRequested(http.Header) bool
	IsEncrypted(map[string]string) bool
}

// IsRequested returns true and the SSE Type if the HTTP headers
// indicate that some form server-side encryption is requested.
//
// If no SSE headers are present then IsRequested returns false
// and no Type.
func IsRequested(h http.Header) (Type, bool) {
	switch {
	case S3.IsRequested(h):
		return S3, true

### 启用代理转发的请求头 { #enable-proxy-forwarded-headers }

你可以用 *CLI 选项* `--forwarded-allow-ips` 启动 FastAPI CLI，并传入应该被信任、允许读取这些转发请求头的 IP 地址列表。

如果设置为 `--forwarded-allow-ips="*"`，就会信任所有来源 IP。

如果你的**服务器**位于受信任的**代理**之后，并且只有代理会与它通信，这将使其接受该**代理**的任何 IP。

      logger.info(String.format("Sending request %s on %s%n%s",
          request.url(), chain.connection(), request.headers()));
      Response response = chain.proceed(request);

      long t2 = System.nanoTime();
      logger.info(String.format("Received response for %s in %.1fms%n%s",
          request.url(), (t2 - t1) / 1e6d, response.headers()));
      return response;
    }
  }

  public static void main(String... args) throws Exception {

Para esos casos, puedes usar un parámetro `Response`.

## Usa un parámetro `Response` { #use-a-response-parameter }

Puedes declarar un parámetro de tipo `Response` en tu *path operation function* (como puedes hacer para cookies y headers).

Y luego puedes establecer el `status_code` en ese objeto de response *temporal*.
