Pythonのformat文字列と同様のシンタックスで「パスパラメータ」や「パス変数」を宣言できます:

{* ../../docs_src/path_params/tutorial001.py hl[6,7] *}

パスパラメータ `item_id` の値は、引数 `item_id` として関数に渡されます。

しがたって、この例を実行して <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a> にアクセスすると、次のレスポンスが表示されます。

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

## パスパラメータと型

標準のPythonの型アノテーションを使用して、関数内のパスパラメータの型を宣言できます:

                    type: array
                    items:
                      type: string
                    example: ["aaa"]
                  related_contents:
                    type: array
                    items:
                      type: string
                    example: []
                  data:
                    type: array
                    items:
                      type: object

Tarayıcımızda şu bağlantıyı açalım <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>.

Aşağıdaki gibi bir JSON yanıtıyla karşılaşacağız:

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

Az önce oluşturduğumuz API:

* `/` ve `/items/{item_id}` <abbr title="Adres / Yol: Path ">_yollarına_</abbr> HTTP isteği alabilir.

    /** Configuration for Fess */
    @Resource
    protected FessConfig fessConfig;

    /**
     * Gets a paginated list of protected words items.
     * @param dictId the dictionary ID
     * @param protwordsPager the pager for pagination
     * @return the list of protected words items
     */
    public List<ProtwordsItem> getProtwordsList(final String dictId, final ProtwordsPager protwordsPager) {

 * governing permissions and limitations under the License.
 */
package org.codelibs.fess.dict;

/**
 * Abstract base class for all dictionary items in the Fess search system.
 * Dictionary items are used to store entries in various dictionaries such as
 * synonyms, kuromoji, protwords, and stopwords dictionaries.
 *
 */
public abstract class DictionaryItem {

For example, let's say you have 4 API endpoints (*path operations*):

* `/items/public/`
* `/items/private/`
* `/users/{user_id}/activate`
* `/items/pro/`

then you could add different permission requirements for each of them just with dependencies and sub-dependencies:

```mermaid
graph TB

    }

    @Override
    public int compareTo(ComparableVersion o) {
        return items.compareTo(o.items);
    }

    @Override
    public String toString() {
        return value;
    }

    public String getCanonical() {
        if (canonical == null) {
            canonical = items.toString();
        }
        return canonical;
    }

    @Override

### Проверка

Откройте браузер на <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>.

Вы увидите следующий JSON ответ:

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

Вы уже создали API, который:

* Получает HTTP-запросы по _путям_ `/` и `/items/{item_id}`.

        // Test sequential ID assignment pattern
        TestDictionaryItem[] items = new TestDictionaryItem[5];

        for (int i = 0; i < items.length; i++) {
            items[i] = new TestDictionaryItem();
            items[i].id = i + 1;
        }

        for (int i = 0; i < items.length; i++) {
            assertEquals(i + 1, items[i].getId());
        }
    }

    public void test_idModification() {
