你可以通过传递额外信息给 `Field` 同样的方式操作`Path`, `Query`, `Body`等。

比如，你可以将请求体的一个 `example` 传递给 `Body`:

# 测试 WebSockets

测试 WebSockets 也使用 `TestClient`。

为此，要在 `with` 语句中使用 `TestClient` 连接 WebSocket。

```Python
q: str | None = None

由于默认情况下单一值被解释为查询参数，因此你不必显式地添加 `Query`，你可以仅执行以下操作：

```Python
q: str = None
```

比如：
