우리 역시 이제부터 메소드를 "**작동**"이라고 부를 것입니다.

#### *경로 작동 데코레이터* 정의

{* ../../docs_src/first_steps/tutorial001.py hl[6] *}

`@app.get("/")`은 **FastAPI**에게 바로 아래에 있는 함수가 다음으로 이동하는 요청을 처리한다는 것을 알려줍니다.

* 경로 `/`
* <abbr title="HTTP GET 메소드"><code>get</code> 작동</abbr> 사용

/// info | `@decorator` 정보

이 `@something` 문법은 파이썬에서 "데코레이터"라 부릅니다.

{* ../../docs_src/first_steps/tutorial001.py h1[6] *}

`@app.get("/")` 告訴 **FastAPI** 那個函式負責處理請求：

* 路徑 `/`
* 使用 <abbr title="HTTP GET 方法"><code>get</code>操作</abbr>

/// info | `@decorator` Info

Python 中的 `@something` 語法被稱為「裝飾器」。

你把它放在一個函式上面。像一個漂亮的裝飾帽子（我猜這是術語的來源）。

一個「裝飾器」會對下面的函式做一些事情。

在這種情況下，這個裝飾器告訴 **FastAPI** 那個函式對應於 **路徑** `/` 和 **操作** `get`.

這就是「**路徑操作裝飾器**」。

///

你也可以使用其他的操作：

        if (logger.isDebugEnabled()) {
            logger.debug("Adding {}", dataMap);
        }

        //   required check
        final Object urlObj = dataMap.get(fessConfig.getIndexFieldUrl());
        if (urlObj == null) {
            throw new DataStoreException("url is null. dataMap=" + dataMap);
        }

   * create, cache and return" pattern. For further improvements, use {@link LoadingCache} and its
   * {@link LoadingCache#get(Object) get(K)} method instead of this one.
   *
   * <p>Among the improvements that this method and {@code LoadingCache.get(K)} both provide are:
   *
   * <ul>
   *   <li>{@linkplain LoadingCache#get(Object) awaiting the result of a pending load} rather than
   *       starting a redundant one
