`from starlette.staticfiles import StaticFiles` da kullanabilirsiniz.

**FastAPI**, geliştirici olarak size kolaylık olsun diye `starlette.staticfiles`'ı `fastapi.staticfiles` olarak da sağlar. Ancak aslında doğrudan Starlette'den gelir.

**FastAPI**, request içindeki **headers** bölümünden **her alan** için veriyi **çıkarır** ve size tanımladığınız Pydantic model örneğini verir.

## Dokümanları Kontrol Edin { #check-the-docs }

Gerekli header'ları `/docs` altındaki doküman arayüzünde görebilirsiniz:

<div class="screenshot">

			accessKey:          credentials.AccessKey,
			secretKey:          credentials.SecretKey,
			expectedRespStatus: http.StatusNoContent,
		},
		// Test case - 2.
		// Setting the content length to be more than max allowed size.
		// Expecting StatusBadRequest (400).
		{
			bucketName:         bucketName,
			bucketPolicyReader: bytes.NewReader(fmt.Appendf(nil, bucketPolicyTemplate, bucketName, bucketName)),

Ahora intenta enviar un ítem inválido como:

```JSON
{
  "title": "towel",
  "size": "XL"
}
```

Recibirás un response que te dirá que los datos son inválidos conteniendo el body recibido:

```JSON hl_lines="12-15"
{
  "detail": [
    {
      "loc": [
        "body",
        "size"
      ],
      "msg": "value is not a valid integer",
      "type": "type_error.integer"
    }

Tente enviar um item inválido como este:

```JSON
{
  "title": "towel",
  "size": "XL"
}
```

Você receberá uma *response* informando-o de que os dados são inválidos, e contendo o *body* recebido:

```JSON hl_lines="12-15"
{
  "detail": [
    {
      "loc": [
        "body",
        "size"
      ],
      "msg": "value is not a valid integer",
      "type": "type_error.integer"

            }

            final StringBuilder buf = new StringBuilder(255);
            buf.append("\"record_count\":").append(docIdList.size());
            buf.append(", \"data\":[");
            if (!docIdList.isEmpty()) {
                for (int i = 0; i < docIdList.size(); i++) {
                    if (i > 0) {
                        buf.append(',');
                    }
