Open your browser at [http://127.0.0.1:8000](http://127.0.0.1:8000).

There you can set:

* The "Item ID", used in the path.
* The "Token" used as a query parameter.

/// tip

Notice that the query `token` will be handled by a dependency.

///

With that you can connect the WebSocket and then send and receive messages:

</div>

Откройте браузер по адресу [http://127.0.0.1:8000](http://127.0.0.1:8000).

Там вы можете задать:

* "Item ID", используемый в пути.
* "Token", используемый как query-параметр.

/// tip | Подсказка

Обратите внимание, что query-параметр `token` будет обработан в зависимости.

///

Теперь вы можете подключиться к веб-сокету и начинать отправку и получение сообщений:

And an `APIRoute` subclass to use that custom request class.

### Create a custom `GzipRequest` class { #create-a-custom-gziprequest-class }

/// tip

This is a toy example to demonstrate how it works, if you need Gzip support, you can use the provided [`GzipMiddleware`](../advanced/middleware.md#gzipmiddleware).

/// tip | İpucu

Test fonksiyonlarının `async def` değil, normal `def` olduğuna dikkat edin.

Client'a yapılan çağrılar da `await` kullanılmadan, normal çağrılardır.

遵循语义版本控制约定，任何低于`1.0.0`的版本都可能会添加 breaking changes。

FastAPI 还遵循这样的约定：任何"PATCH"版本更改都是为了bug修复和non-breaking changes。

/// tip | 提示

"PATCH"是最后一个数字，例如，在`0.2.3`中，PATCH版本是`3`。

///

因此，你应该能够固定到如下版本：

```txt
fastapi>=0.45.0,<0.46.0
```

"MINOR"版本中会添加breaking changes和新功能。

/// tip | 提示

"MINOR"是中间的数字，例如，在`0.2.3`中，MINOR版本是`2`。

///

## 升级FastAPI版本 { #upgrading-the-fastapi-versions }

Aber jetzt, mit `Query(max_length=50)` innerhalb von `Annotated`, sagen wir FastAPI, dass wir eine **zusätzliche Validierung** für diesen Wert wünschen, wir wollen, dass er maximal 50 Zeichen hat. 😎

/// tip | Tipp

Hier verwenden wir `Query()`, weil dies ein **Query-Parameter** ist. Später werden wir andere wie `Path()`, `Body()`, `Header()`, und `Cookie()` sehen, die auch dieselben Argumente wie `Query()` akzeptieren.

///

Mas agora, com `Query(max_length=50)` dentro de `Annotated`, estamos dizendo ao FastAPI que queremos validação adicional para este valor, queremos que tenha no máximo 50 caracteres. 😎

/// tip | Dica

Aqui estamos usando `Query()` porque este é um parâmetro de consulta. Mais adiante veremos outros como `Path()`, `Body()`, `Header()` e `Cookie()`, que também aceitam os mesmos argumentos que `Query()`.
