`app.add_middleware()`는 첫 번째 인수로 미들웨어 클래스와 미들웨어에 전달할 추가 인수를 받습니다.

## 통합 미들웨어

**FastAPI**에는 일반적인 사용 사례를 위한 여러 미들웨어가 포함되어 있으며, 사용 방법은 다음에서 살펴보겠습니다.

/// note | 기술 세부 사항

다음 예제에서는 `from starlette.middleware.something import SomethingMiddleware`를 사용할 수도 있습니다.

**FastAPI**는 개발자의 편의를 위해 `fastapi.middleware`에 여러 미들웨어를 제공합니다. 그러나 사용 가능한 대부분의 미들웨어는 Starlette에서 직접 제공합니다.

## `HTTPSRedirectMiddleware`

But keep in mind that, as everything is handled in memory, in a single list, it will only work while the process is running, and will only work with a single process.

If you need something easy to integrate with FastAPI but that is more robust, supported by Redis, PostgreSQL or others, check <a href="https://github.com/encode/broadcaster" class="external-link" target="_blank">encode/broadcaster</a>.

Now, imagine that with **many** other **packages** that all your **projects depend on**. That's very difficult to manage. And you would probably end up running some projects with some **incompatible versions** of the packages, and not knowing why something isn't working.

        LogStream.setInstance(testStream);
        LogStream instance = LogStream.getInstance();

        // Write something to verify it uses our test stream
        instance.println("test message");
        instance.flush();
        String output = testOutput.toString();
        assertTrue(output.contains("test message"));
