**FastAPI** **extraerá** los datos de **cada campo** de los **form data** en el request y te dará el modelo de Pydantic que definiste.

## Prohibir Campos de Formulario Extra { #forbid-extra-form-fields }

**FastAPI**, request içindeki **form data**'dan **her bir field** için veriyi **çıkarır** ve size tanımladığınız Pydantic model'ini verir.

## `Request` nesnesi hakkında detaylar { #details-about-the-request-object }

**FastAPI** aslında altta **Starlette** çalıştırır ve üstüne çeşitli araçlardan oluşan bir katman ekler. Bu yüzden gerektiğinde Starlette'in [`Request`](https://www.starlette.dev/requests/) nesnesini doğrudan kullanabilirsiniz.

    CharSequenceReader reader = new CharSequenceReader(string);
    assertTrue(reader.markSupported());

    assertThat(readFully(reader)).isEqualTo(string);
    assertFullyRead(reader);

    // reset and read again
    reader.reset();
    assertThat(readFully(reader)).isEqualTo(string);
    assertFullyRead(reader);

    // reset, skip, mark, then read the rest
    reader.reset();
    assertEquals(5, reader.skip(5));

            this.inputStream = inputStream;
            return this;
        }

        public XmlReaderRequestBuilder reader(Reader reader) {
            this.reader = reader;
            return this;
        }

        public XmlReaderRequestBuilder transformer(Transformer transformer) {
            this.transformer = transformer;
            return this;

# Using the Request Directly { #using-the-request-directly }

Up to now, you have been declaring the parts of the request that you need with their types.

Taking data from:

* The path as parameters.
* Headers.
* Cookies.
* etc.

And by doing so, **FastAPI** is validating that data, converting it and generating documentation for your API automatically.

But there are situations where you might need to access the `Request` object directly.

**FastAPI** will **extract** the data for **each field** from the **form data** in the request and give you the Pydantic model you defined.

## Check the Docs { #check-the-docs }

You can verify it in the docs UI at `/docs`:

## Forbid Extra Form Fields { #forbid-extra-form-fields }

**FastAPI**는 요청에서 받은 **폼 데이터**에서 **각 필드**에 대한 데이터를 **추출**하고 정의한 Pydantic 모델을 줍니다.

## 문서 확인하기 { #check-the-docs }

문서 UI `/docs`에서 확인할 수 있습니다:

## 추가 폼 필드 금지하기 { #forbid-extra-form-fields }

일부 특별한 사용 사례(아마도 흔하지는 않겠지만)에서는 Pydantic 모델에서 선언된 폼 필드로만 **제한**하길 원할 수도 있습니다. 그리고 **추가** 필드를 **금지**할 수도 있습니다.

## Détails sur l'objet `Request` { #details-about-the-request-object }

Comme **FastAPI** est en fait **Starlette** en dessous, avec une couche de plusieurs outils au-dessus, vous pouvez utiliser directement l'objet [`Request`](https://www.starlette.dev/requests/) de Starlette lorsque vous en avez besoin.

    CharSequenceReader reader = new CharSequenceReader(string);
    assertTrue(reader.markSupported());

    assertThat(readFully(reader)).isEqualTo(string);
    assertFullyRead(reader);

    // reset and read again
    reader.reset();
    assertThat(readFully(reader)).isEqualTo(string);
    assertFullyRead(reader);

    // reset, skip, mark, then read the rest
    reader.reset();
    assertEquals(5, reader.skip(5));
