### Criar uma classe `GzipRoute` personalizada { #create-a-custom-gziproute-class }

Em seguida, criamos uma subclasse personalizada de `fastapi.routing.APIRoute` que fará uso do `GzipRequest`.

Dessa vez, ele irá sobrescrever o método `APIRoute.get_route_handler()`.

Esse método retorna uma função. E essa função é o que irá receber uma requisição e retornar uma resposta.

    Works with **any HTTP method** (`GET`, `POST`, etc.), which makes it compatible
    with protocols like MCP that stream SSE over `POST`.

    The actual encoding logic lives in the FastAPI routing layer. This class
    serves mainly as a marker and sets the correct `Content-Type`.

/**

# The country of the subject. Two letter code.

# The common name of the certificate owner.

### Eine benutzerdefinierte `GzipRoute`-Klasse erstellen { #create-a-custom-gziproute-class }

Als Nächstes erstellen wir eine benutzerdefinierte Unterklasse von `fastapi.routing.APIRoute`, welche `GzipRequest` nutzt.

Dieses Mal wird die Methode `APIRoute.get_route_handler()` überschrieben.

    }

    @Test
    @DisplayName("close calls release and decrements usage; double release throws")
    void closeAndReleaseBehavior() {
        // Validates usage counting and that an extra release() throws RuntimeCIFSException
        // First close -> usage 1 -> 0, triggers treeConnection.release()
        handle.close();
        verify(treeConnection, times(1)).release();

如此一來，相同的路由類別即可同時處理經 gzip 壓縮與未壓縮的請求。

### 建立自訂的 `GzipRoute` 類別 { #create-a-custom-gziproute-class }

接著，我們建立 `fastapi.routing.APIRoute` 的自訂子類別，讓它使用 `GzipRequest`。

這次，它會覆寫 `APIRoute.get_route_handler()` 方法。

這個方法會回傳一個函式，而該函式會接收請求並回傳回應。

在這裡，我們用它將原始的請求包裝成 `GzipRequest`。
