## Campos do tipo Lista com um parâmetro de tipo { #list-fields-with-type-parameter }

Mas o Python tem uma maneira específica de declarar listas com tipos internos ou "parâmetros de tipo":

### Declare uma `list` com um parâmetro de tipo { #declare-a-list-with-a-type-parameter }

Para declarar tipos que têm parâmetros de tipo (tipos internos), como `list`, `dict`, `tuple`,

## 自訂 `PNGStreamingResponse` { #a-custom-pngstreamingresponse }

在上述範例中，雖然串流了資料位元組，但回應沒有 `Content-Type` 標頭，因此用戶端不知道接收到的是哪種資料型別。

你可以建立 `StreamingResponse` 的自訂子類別，將 `Content-Type` 標頭設定為你要串流的資料型別。

例如，你可以建立 `PNGStreamingResponse`，透過 `media_type` 屬性把 `Content-Type` 設為 `image/png`：

{* ../../docs_src/stream_data/tutorial002_py310.py ln[6,19:20] hl[20] *}

 * what names a host registers with the nbtstat command.
 *
 *  * <blockquote>
 *
 * <pre>
 * C:\&gt;nbtstat -a 192.168.1.15
 *
 *        NetBIOS Remote Machine Name Table
 *
 *    Name               Type         Status
 * ---------------------------------------------
 * JMORRIS2        &lt;00&gt;  UNIQUE      Registered
 * BILLING-NY      &lt;00&gt;  GROUP       Registered
 * JMORRIS2        &lt;03&gt;  UNIQUE      Registered

Можна створити власний підклас `StreamingResponse`, який встановлює заголовок `Content-Type` відповідно до типу даних, що ви стрімите.

Наприклад, можна створити `PNGStreamingResponse`, який встановлює заголовок `Content-Type` у `image/png` за допомогою атрибута `media_type`:

	"errors"
	"flag"
	"fmt"
	"log"
	"net/url"
	"os"
	"path/filepath"
	"strings"
	"syscall"

type xl struct {
	This string     `json:"this"`
	Sets [][]string `json:"sets"`
}

type format struct {
	ID string `json:"id"`
	XL xl     `json:"xl"`
}

func getMountMap() (map[string]string, error) {
	result := make(map[string]string)

	// WriteBufferSize 64KiB moving up from 4KiB default
	WriteBufferSize = 64 << 10

	// ReadBufferSize 64KiB moving up from 4KiB default
	ReadBufferSize = 64 << 10
)

// ConnSettings - contains connection settings.
type ConnSettings struct {
	DialContext DialContext // Custom dialContext, DialTimeout is ignored if this is already setup.
	LookupHost  LookupHost  // Custom lookupHost, is nil on containerized deployments.
	DialTimeout time.Duration
