## A Custom `PNGStreamingResponse` { #a-custom-pngstreamingresponse }

In the examples above, the data bytes were streamed, but the response didn't have a `Content-Type` header, so the client didn't know what type of data it was receiving.

You can create a custom sub-class of `StreamingResponse` that sets the `Content-Type` header to the type of data you're streaming.

    # o applicationOutsideSqlMap: (NotRequired - Default map:{})
    #  You can set additional users.
    #  Elements of this map are as below:
    #   o key of map: a relative path to the application project from DBFlute client
    #   o sqlDirectory: SQL directory as a relative path from the application directory 
    #     (NotRequired - Default Java:'src/main/java' & 'src/main/resources' CSharp:'source')

# Background Tasks { #background-tasks }

You can define background tasks to be run *after* returning a response.

This is useful for operations that need to happen after a request, but that the client doesn't really have to be waiting for the operation to complete before receiving the response.

This includes, for example:

* Email notifications sent after performing an action:

Vous pouvez désormais obtenir l'utilisateur actuel directement dans votre *fonction de chemin d'accès*.

Nous avons déjà fait la moitié du chemin.

Il nous suffit d'ajouter un *chemin d'accès* pour que l'utilisateur/client envoie effectivement le `username` et le `password`.

	"encoding/json"
	"strconv"

// conn represents a connection to a KMS implementation.
// It's implemented by the MinKMS and KES client wrappers
// and the static / single key KMS.
type conn interface {
	// Version returns version information about the KMS.
	//
	// TODO(aead): refactor this API call. It does not account
	// for multiple endpoints.

## Eine benutzerdefinierte `PNGStreamingResponse` { #a-custom-pngstreamingresponse }

In den obigen Beispielen wurden die Datenbytes gestreamt, aber die Response hatte keinen `Content-Type`-Header, sodass der Client nicht wusste, welchen Datentyp er erhielt.

Sie können eine benutzerdefinierte Unterklasse von `StreamingResponse` erstellen, die den `Content-Type`-Header auf den Typ der gestreamten Daten setzt.

我们现在可以使用应用程序创建一个 `AsyncClient` ，并使用 `await` 向其发送异步请求。

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[9:12] *}

这相当于：

```Python
response = client.get('/')
```

...我们曾经通过它向 `TestClient` 发出请求。

/// tip | 提示

请注意，我们正在将 async/await 与新的 `AsyncClient` 一起使用——请求是异步的。
