## Corpo da requisição + parâmetros de rota + parâmetros de consulta { #request-body-path-query-parameters }

Você também pode declarar parâmetros de **corpo**, **rota** e **consulta**, ao mesmo tempo.

O **FastAPI** irá reconhecer cada um deles e retirar a informação do local correto.

Ancak, birçok farklı function veya class tanımlamak zorunda kalmadan, dependency üzerinde bazı parametreler ayarlamak isteyebileceğiniz durumlar olabilir.

Örneğin, query parametresi `q`'nun belirli bir sabit içeriği barındırıp barındırmadığını kontrol eden bir dependency istediğimizi düşünelim.

Ama bu sabit içeriği parametreleştirebilmek istiyoruz.

Но бывают случаи, когда нужно задавать параметры зависимости, не объявляя много разных функций или классов.

Представим, что нам нужна зависимость, которая проверяет, содержит ли query-параметр `q` некоторое фиксированное содержимое.

Но при этом мы хотим иметь возможность параметризовать это фиксированное содержимое.

## «Вызываемый» экземпляр { #a-callable-instance }

    val encodedPathSegments: List<String> = httpUrl.encodedPathSegments
    val pathSegments: List<String> = httpUrl.pathSegments
    val encodedQuery: String? = httpUrl.encodedQuery
    val query: String? = httpUrl.query
    val querySize: Int = httpUrl.querySize
    val queryParameter: String? = httpUrl.queryParameter("")
    val queryParameterNames: Set<String> = httpUrl.queryParameterNames

### 「dependant」での依存関係の宣言 { #declare-the-dependency-in-the-dependant }

*path operation 関数*のパラメータに`Body`や`Query`などを使用するのと同じように、新しいパラメータに`Depends`を使用することができます:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

関数のパラメータに`Depends`を使用するのは`Body`や`Query`などと同じですが、`Depends`の動作は少し異なります。

`Depends`は１つのパラメータしか与えられません。

このパラメータは関数のようなものである必要があります。

        private final long allRecordCount;

        TestSearcher(long allRecordCount) {
            this.allRecordCount = allRecordCount;
        }

        @Override
        protected SearchResult search(String query, SearchRequestParams params, OptionalThing<FessUserBean> userBean) {
            int start = params.getStartPosition();
            int size = params.getPageSize();
            SearchResultBuilder builder = SearchResult.create();

 * Futures.addCallback}.) Still, direct {@code addListener} calls are occasionally useful:
 *
 * {@snippet :
 * final String name = ...;
 * inFlight.add(name);
 * ListenableFuture<Result> future = service.query(name);
 * future.addListener(new Runnable() {
 *   public void run() {

 *     logger.info("Done with {0}", name);

   * unprivileged user may return a resource accessible only to a privileged user making a similar
   * call. To prevent this problem, create a key object that includes all values that affect the
   * result of the query. Or use {@code LoadingCache.get(K)}, which lacks the ability to refer to
   * state other than that in the key.
   *
   * <p><b>Warning:</b> as with {@link CacheLoader#load}, {@code loader} <b>must not</b> return

위 예제에서 입력 모델은 Pydantic v1 모델이고, 출력 모델(`response_model=ItemV2`로 정의됨)은 Pydantic v2 모델입니다.

### Pydantic v1 파라미터 { #pydantic-v1-parameters }

Pydantic v1 모델과 함께 `Body`, `Query`, `Form` 등 파라미터용 FastAPI 전용 도구 일부를 사용해야 한다면, Pydantic v2로의 마이그레이션을 마칠 때까지 `fastapi.temp_pydantic_v1_params`에서 import할 수 있습니다:
