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

그래서 이 예제를 실행하고 <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>로 이동하면, 다음 응답을 볼 수 있습니다:

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

## 타입이 있는 매개변수

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

     *
     * @param item the character mapping item to update
     */
    @Override
    public synchronized void update(final CharMappingItem item) {
        try (MappingUpdater updater = new MappingUpdater(item)) {
            reload(updater);
        }
    }

    /**
     * Deletes a character mapping item from the dictionary file.
     *

                    request.getArtifact(),
                    request.getRemoteRepositories());
        }
    }

    private static <T> List<T> toList(Collection<T> items) {
        return (items != null) ? new ArrayList<>(items) : null;
    }

    /** The list of suggested items. */
    protected final List<SuggestItem> items;

    /**
     * Constructor for SuggestResponse.
     * @param index The index name.
     * @param tookMs The time taken in milliseconds.
     * @param words The list of suggested words.
     * @param total The total number of hits.
     * @param items The list of suggested items.
     */

    String simple = "a,b,c,d";
    Iterable<String> items = COMMA_SPLITTER.limit(1).split(simple);
    assertThat(items).containsExactly("a,b,c,d").inOrder();
  }

  public void testLimitSeparator() {
    String simple = "a,b,c,d";
    Iterable<String> items = COMMA_SPLITTER.limit(2).split(simple);
    assertThat(items).containsExactly("a", "b,c,d").inOrder();
  }

Vous devriez pouvoir accéder à votre application via l'URL de votre conteneur Docker, par exemple : <a href="http://192.168.99.100/items/5?q=somequery" class="external-link" target="_blank">http://192.168.99.100/items/5?q=somequery</a> ou <a href="http://127.0.0.1/items/5?q=somequery" class="external-link" target="_blank">http://127.0.0.1/items/5?q=somequery</a> (ou équivalent, en utilisant votre hôte Docker).

Vous verrez quelque chose comme :

```JSON

### Kiểm tra

Mở trình duyệt của bạn tại <a href="http://127.0.0.1:8000/items/5?q=somequery" class="external-link" target="_blank">http://127.0.0.1:8000/items/5?q=somequery</a>.

Bạn sẽ thấy một JSON response:

```JSON
{"item_id": 5, "q": "somequery"}
```

Bạn đã sẵn sàng để tạo một API như sau:

* Nhận HTTP request với _đường dẫn_ `/` và `/items/{item_id}`.
