### 代理轉發標頭如何運作 { #how-proxy-forwarded-headers-work }

以下是「代理」在用戶端與「應用伺服器」之間加入轉發標頭的視覺化示意：

```mermaid
sequenceDiagram
    participant Client
    participant Proxy as Proxy/Load Balancer
    participant Server as FastAPI Server

    Client->>Proxy: HTTPS Request<br/>Host: mysuperapp.com<br/>Path: /items

    Note over Proxy: Proxy adds forwarded headers

Para retornar ao cliente *responses* HTTP com erros, use o `HTTPException`.

### Import `HTTPException` { #import-httpexception }

{* ../../docs_src/handling_errors/tutorial001_py310.py hl[1] *}

### Lance o `HTTPException` no seu código { #raise-an-httpexception-in-your-code }

`HTTPException`, ao fundo, nada mais é do que a conjunção entre uma exceção comum do Python e informações adicionais relevantes para APIs.

 *           // Services have been initialized and are healthy, start accepting requests...
 *         }
 *         public void failure(Service service) {
 *           // Something failed, at this point we could log it, notify a load balancer, or take
 *           // some other action.  For now we will just exit.
 *           System.exit(1);
 *         }
 *       },
 *       MoreExecutors.directExecutor());

그런 경우에는 [위에서 설명한 대로](#dockerfile) 의존성을 설치하고, 여러 Uvicorn 워커를 사용하는 대신 **단일 Uvicorn 프로세스**를 실행하는 **처음부터 만든 Docker 이미지**를 사용하는 것이 좋을 것입니다.

### 로드 밸런서 { #load-balancer }

컨테이너를 사용할 때는 보통 **메인 포트에서 대기(listening)하는** 컴포넌트가 있습니다. **HTTPS**를 처리하기 위한 **TLS 종료 프록시** 역할을 하는 다른 컨테이너일 수도 있고, 유사한 도구일 수도 있습니다.

이 컴포넌트가 요청의 **부하(load)**를 받아 워커들에 (가능하면) **균형 있게** 분산한다면, 보통 **로드 밸런서**라고 부릅니다.

unauthenticated. The mitigation may be enabled by setting the `UnauthenticatedHTTP2DOSMitigation` feature gate to `true` (it is disabled by default). An API server fronted by an L7 load balancer that already mitigates these http/2 attacks may choose not to enable the kube-apiserver mitigation to avoid disrupting load balancer → kube-apiserver connections if http/2 requests from multiple clients share the same backend connection. An API server on a private network may choose not to enable the kube-apiserver...

### 代理转发请求头如何工作 { #how-proxy-forwarded-headers-work }

下面是一个可视化图示，展示了**代理**如何在客户端与**应用服务器**之间添加转发请求头：

```mermaid
sequenceDiagram
    participant Client
    participant Proxy as Proxy/Load Balancer
    participant Server as FastAPI Server

    Client->>Proxy: HTTPS Request<br/>Host: mysuperapp.com<br/>Path: /items

    Note over Proxy: Proxy adds forwarded headers
