El valor del parámetro de path `item_id` se pasará a tu función como el argumento `item_id`.

Así que, si ejecutas este ejemplo y vas a <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>, verás un response de:

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

## Parámetros de path con tipos

Puedes declarar el tipo de un parámetro de path en la función, usando anotaciones de tipos estándar de Python:

        url = "file://C .doc";
        exp = "file://C .doc";
        assertEquals(exp, transformer.decodeUrlAsName(url, true));

        url = "http://example.com/foo/" + encodeUrl("#") + "/@@bar/index.html#fragment?foo=bar";
        exp = "http://example.com/foo/#/@@bar/index.html#fragment?foo=bar";
        assertEquals(exp, transformer.decodeUrlAsName(url, false));
    }

    public void test_getFileName_ok() throws Exception {

이는 **FastAPI**가 다음과 유사한 본문을 기대한다는 것을 의미합니다:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

다시 한번, **FastAPI**를 사용하여 해당 선언을 함으로써 얻는 것은:

* 중첩 모델도 편집기 지원(자동완성 등)
* 데이터 변환

    public void testToJarFilePath() throws Exception {
        final File f = new File("/Program Files/foo.jar");
        final URL url = new URL("jar:" + f.toURI().toURL() + "!/");
        final String root = new File("/").getCanonicalPath();
        assertEquals(root + "Program Files" + File.separator + "foo.jar", JarFileUtil.toJarFilePath(url));
    }

    /**
     * @throws Exception

이 경우, 아래로 이동하면:

```

또는

```

```

또는

```
http://127.0.0.1:8000/items/foo?short=true
```

또는

```
http://127.0.0.1:8000/items/foo?short=on
```

또는

```
http://127.0.0.1:8000/items/foo?short=yes
```
