這將是你建立所有 API 的主要互動點。

### 第三步：建立一個 *路徑操作*

#### 路徑

這裡的「路徑」指的是 URL 中自第一個 `/` 以後的部分。

例如，在 URL 中：

```
https://example.com/items/foo
```

……的路徑將會是：

```
/items/foo
```

/// info

「路徑」也常被稱為「端點 endpoint」或「路由 route」。

///

在建置 API 時，「路徑」是分離「關注點」和「資源」的主要方式。

#### 操作

這裡的「操作」指的是 HTTP 的「方法」之一。

其中包括：

```

</div>

### 3 단계: *경로 작동* 생성

#### 경로

여기서 "경로"는 첫 번째 `/`부터 시작하는 URL의 뒷부분을 의미합니다.

그러므로 아래와 같은 URL에서:

```
https://example.com/items/foo
```

...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

responses = {
    404: {"description": "Item not found"},
    302: {"description": "The item was moved"},
    403: {"description": "Not enough privileges"},
}


app = FastAPI()


@app.get(
    "/items/{item_id}",
    response_model=Item,
    responses={**responses, 200: {"content": {"image/png": {}}}},
)
async def read_item(item_id: str, img: bool | None = None):
    if img:
