我们甚至可以声明[全局依赖项](dependencies/global-dependencies.md)，它会和每个 `APIRouter` 的依赖项组合在一起：

{* ../../docs_src/bigger_applications/app_an_py310/main.py hl[1,3,7] title["app/main.py"] *}

### 导入 `APIRouter` { #import-the-apirouter }

现在，我们导入具有 `APIRouter` 的其他子模块：

{* ../../docs_src/bigger_applications/app_an_py310/main.py hl[4:5] title["app/main.py"] *}

由于文件 `app/routers/users.py` 和 `app/routers/items.py` 是同一 Python 包 `app` 一个部分的子模块，因此我们可以使用单个点 ` .` 通过「相对导入」来导入它们。

보안을 처리하기 위해 **FastAPI**가 제공하는 도구들을 사용해 봅시다.

## 어떻게 보이는지 { #how-it-looks }

먼저 코드를 그냥 사용해서 어떻게 동작하는지 보고, 그다음에 무슨 일이 일어나는지 이해하러 다시 돌아오겠습니다.

## `main.py` 만들기 { #create-main-py }

예제를 파일 `main.py`에 복사하세요:

{* ../../docs_src/security/tutorial001_an_py310.py *}

## 실행하기 { #run-it }

/// info | 정보

## Do not Separate Schemas { #do-not-separate-schemas }

Now, there are some cases where you might want to have the **same schema for input and output**.

Probably the main use case for this is if you already have some autogenerated client code/SDKs and you don't want to update all the autogenerated client code/SDKs yet, you probably will want to do it at some point, but maybe not right now.

                affectedRegistrations++;
            }
        }

        log.debug("Notification affects {} registrations", affectedRegistrations);
    }

    /**
     * Main server loop - simplified implementation
     */
    private void runServer() {
        while (running.get() && !serverSocket.isClosed()) {
            try {
                Socket clientSocket = serverSocket.accept();

Note that only some sub-projects in the Elasticsearch project are currently
fully-formatted. You can see a list of project that **are not**
automatically formatted in
[build-tools-internal/src/main/groovy/elasticsearch.formatting.gradle](build-tools-internal/src/main/groovy/elasticsearch.formatting.gradle).

### Importing the project into Eclipse

Elasticsearch builds using Gradle and Java 16. When importing into Eclipse you
