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:

    assert response.status_code == 200, response.text
    response = client.post("/example/", json={"data": "Foo"})
    assert response.status_code == 200, response.text
    response = client.post("/examples/", json={"data": "Foo"})
    assert response.status_code == 200, response.text
    response = client.post("/example_examples/", json={"data": "Foo"})

swagger_ui_oauth2_redirect_url = "/docs/redirect"

app = FastAPI(swagger_ui_oauth2_redirect_url=swagger_ui_oauth2_redirect_url)


@app.get("/items/")
async def read_items():
    return {"id": "foo"}


client = TestClient(app)


def test_swagger_ui():
    response = client.get("/docs")
    assert response.status_code == 200, response.text

@app.get("/items/coerce", response_model=Item)
def get_coerce():
    return {"name": "coerce", "price": "1.0"}


@app.get("/items/validlist", response_model=list[Item])
def get_validlist():
    return [
        {"name": "foo"},
        {"name": "bar", "price": 1.0},
        {"name": "baz", "price": 2.0, "owner_ids": [1, 2, 3]},
    ]


client = TestClient(app)


def test_valid():
    response = client.get("/items/valid")

Це означатиме, що  **FastAPI**  очікуватиме тіло запиту такого вигляду:

```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"
    }
}
```

Завдяки такій декларації у **FastAPI** ви отримуєте:
