### 태그 사용

`tags` 매개변수를 *경로 작동* 및 `APIRouter`와 함께 사용하여 태그에 할당할 수 있습니다:

{* ../../docs_src/metadata/tutorial004.py hl[21,26] *}

/// info

태그에 대한 자세한 내용은 [경로 작동 구성](path-operation-configuration.md#tags){.internal-link target=_blank}에서 읽어보세요.

                }
                throw new ExtractException("PDFBox process cannot finish in " + timeout + " sec.");
            }
            if (!exceptionSet.isEmpty()) {
                throw exceptionSet.iterator().next();
            }
            writer.flush();
            final ExtractData extractData = new ExtractData(writer.toString());
            extractMetadata(document, extractData);
            return extractData;

...경로는 다음과 같습니다:

```
/items/foo
```

/// info | 정보

"경로"는 일반적으로 "엔드포인트" 또는 "라우트"라고도 불립니다.

///

API를 설계할 때 "경로"는 "관심사"와 "리소스"를 분리하기 위한 주요한 방법입니다.

#### 작동

"작동(Operation)"은 HTTP "메소드" 중 하나를 나타냅니다.

다음 중 하나이며:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...흔히 사용되지 않는 것들도 있습니다:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

你可以自由地使用每個操作（HTTP 方法）。

**FastAPI** 不強制任何特定的意義。

這裡的資訊作為一個指南，而不是要求。

例如，當使用 GraphQL 時，你通常只使用 `POST` 操作。

///

### 第四步：定義 **路徑操作函式**

這是我們的「**路徑操作函式**」：

* **path**: 是 `/`.
* **operation**: 是 `get`.
* **function**: 是裝飾器下面的函式（在 `@app.get("/")` 下面）。

{* ../../docs_src/first_steps/tutorial001.py h1[7] *}

這就是一個 Python 函式。

它將會在 **FastAPI** 收到一個請求時被呼叫，使用 `GET` 操作。
