E.g.:

* To pass a *path* or *query* parameter, add it to the URL itself.
* To pass a JSON body, pass a Python object (e.g. a `dict`) to the parameter `json`.
* If you need to send *Form Data* instead of JSON, use the `data` parameter instead.
* To pass *headers*, use a `dict` in the `headers` parameter.
* For *cookies*, a `dict` in the `cookies` parameter.

### Parámetros de Pydantic v1 { #pydantic-v1-parameters }

Si necesitas usar algunas de las herramientas específicas de FastAPI para parámetros como `Body`, `Query`, `Form`, etc. con modelos de Pydantic v1, puedes importarlas de `fastapi.temp_pydantic_v1_params` mientras terminas la migración a Pydantic v2:

{* ../../docs_src/pydantic_v1_in_v2/tutorial004_an_py310.py hl[4,18] *}

<h4 id="General_interfaces">General interfaces</h4>

<p>
In their most general form, an interface element may also be an arbitrary type term
<code>T</code>, or a term of the form <code>~T</code> specifying the underlying type <code>T</code>,
or a union of terms <code>t<sub>1</sub>|t<sub>2</sub>|…|t<sub>n</sub></code>

 * contains information about the named HTML entities such as {@code &} and {@code "} while
 * {@link #escapeUnsafe} is overridden to handle general escaping of the form {@code &#NNNNN;}.
 *
 * <p>The size of the data structure used by {@link ArrayBasedUnicodeEscaper} is proportional to the
 * highest valued code point that requires escaping. For example a replacement map containing the

            if (numTokens == 2) {
                goal.append(tok[1]);
            }

            // This is the case where someone has executed a single goal from the command line
            // of the form:
            //
            // mvn remote-resources:process
            //
            // From the metadata stored on the server which has been created as part of a standard

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:

{* ../../docs_src/pydantic_v1_in_v2/tutorial004_an_py310.py hl[4,18] *}

{* ../../docs_src/path_operation_advanced_configuration/tutorial003_py310.py hl[6] *}

## docstring에서 고급 설명 가져오기 { #advanced-description-from-docstring }

OpenAPI에 사용할 *경로 처리 함수*의 docstring 줄 수를 제한할 수 있습니다.

`\f`(이스케이프된 "form feed" 문자)를 추가하면 **FastAPI**는 이 지점에서 OpenAPI에 사용할 출력 내용을 잘라냅니다.

문서에는 표시되지 않지만, Sphinx 같은 다른 도구는 나머지 부분을 사용할 수 있습니다.

{* ../../docs_src/path_operation_advanced_configuration/tutorial004_py310.py hl[17:27] *}

* Dönen veriyi Pydantic kullanarak JSON’a **serileştirmek**; Pydantic **Rust** ile yazıldığı için **çok daha hızlıdır**.

Ama en önemlisi:

* Çıktı verisini, dönüş tipinde tanımlı olana göre **sınırlar ve filtreler**.
    * Bu, özellikle **güvenlik** açısından önemlidir; aşağıda daha fazlasını göreceğiz.

## `response_model` Parametresi { #response-model-parameter }
