Каждый возвращаемый через `yield` элемент кодируется как JSON и отправляется в поле `data:` события SSE.

Если вы объявите тип возврата как `AsyncIterable[Item]`, FastAPI будет использовать его, чтобы выполнить **валидацию**, добавить **документацию** и **сериализовать** данные с помощью Pydantic.

### 3 단계: *경로 처리* 생성 { #step-3-create-a-path-operation }

#### 경로 { #path }

여기서 "경로"는 첫 번째 `/`부터 시작하는 URL의 뒷부분을 의미합니다.

그러므로 아래와 같은 URL에서:

```
https://example.com/items/foo
```

...경로는 다음과 같습니다:

```
/items/foo
```

/// info | 정보

"경로"는 일반적으로 "엔드포인트" 또는 "라우트"라고도 불립니다.

///

API를 설계할 때 "경로"는 "관심사"와 "리소스"를 분리하기 위한 주요한 방법입니다.

#### 작동 { #operation }

                    // Filtering an array is NOT in place
                    result.acceptedApiChanges = result.acceptedApiChanges.filter((item, pos, ary) => (!pos || (JSON.stringify(item) != JSON.stringify(ary[pos - 1]))));
                    return result;
                }

                function acceptAllErrorCorrections() {

			}
		}
		return true
	})

	if iamOS, ok := store.IAMStorageAPI.(*IAMObjectStore); ok {
		for item := range listIAMConfigItems(context.Background(), iamOS.objAPI, iamConfigPrefix+SlashSeparator+policyDBSTSUsersListKey) {
			user := strings.TrimSuffix(item.Item, ".json")
			if userPredicate != nil && !userPredicate(user) {
				continue
			}

			decodeUser := user

        urls.add("");
        urls.add("   ");
        urls.add(null);

        Set<RequestData> result = crawlerThread.getAnchorSet(urls);
        assertNull(result, "getAnchorSet should return null when all items are filtered out");
    }

    /**

    @Test
    public void test_getAnchorSet_withUnsupportedType() {

    * `url` (**required**): a `str` with the URL for the external documentation.

### Create metadata for tags { #create-metadata-for-tags }

Let's try that in an example with tags for `users` and `items`.

Create metadata for your tags and pass it to the `openapi_tags` parameter:

{* ../../docs_src/metadata/tutorial004_py310.py hl[3:16,18] *}

    approved_reviews = [
        review for review in review_by_user.values() if review.state == "APPROVED"
    ]
    config = settings.config or default_config
    for approved_label, conf in config.items():
        logging.debug(f"Processing config: {conf.model_dump_json()}")
        if conf.await_label is None or (conf.await_label in pr_label_by_name):
            logging.debug(f"Processable PR: {pr.number}")

İstediğiniz kadar derin iç içe modeller tanımlayabilirsiniz:

{* ../../docs_src/body_nested_models/tutorial007_py310.py hl[7,12,18,21,25] *}

/// info | Bilgi

`Offer`’ın bir `Item` list’i olduğuna, `Item`’ların da opsiyonel bir `Image` list’ine sahip olduğuna dikkat edin.

</div>

## Проверка { #check-it }

Проверьте работу по адресу вашего Docker-хоста, например: [http://192.168.99.100/items/5?q=somequery](http://192.168.99.100/items/5?q=somequery) или [http://127.0.0.1/items/5?q=somequery](http://127.0.0.1/items/5?q=somequery) (или аналогичный URL вашего Docker-хоста).

Вы увидите что-то вроде:

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