경로 매개변수 `item_id`의 값은 함수의 `item_id` 인자로 전달됩니다.

그래서 이 예제를 실행하고 [http://127.0.0.1:8000/items/foo](http://127.0.0.1:8000/items/foo)로 이동하면, 다음 응답을 볼 수 있습니다:

```JSON
{"item_id":"foo"}
```

## 타입이 있는 경로 매개변수 { #path-parameters-with-types }

파이썬 표준 타입 어노테이션을 사용하여 함수에 있는 경로 매개변수의 타입을 선언할 수 있습니다:

但如果你在瀏覽器前往 [http://127.0.0.1:8000/items/foo](http://127.0.0.1:8000/items/foo)，你會看到漂亮的 HTTP 錯誤：

```JSON
{
  "detail": [
    {
      "type": "int_parsing",
      "loc": [
        "path",

      ],
      "msg": "Input should be a valid integer, unable to parse string as an integer",
      "input": "foo"
    }
  ]
}
```

因為路徑參數 `item_id` 的值是 `"foo"`，它不是 `int`。
