If for some reason you need to disable this automatic conversion, you can do it as well for Pydantic models for header parameters.

/// warning

Before setting `convert_underscores` to `False`, bear in mind that some HTTP proxies and servers disallow the usage of headers with underscores.

To achieve that, import `JSONResponse`, and return your content there directly, setting the `status_code` that you want:

{* ../../docs_src/additional_status_codes/tutorial001_an_py310.py hl[4,25] *}

/// warning

When you return a `Response` directly, like in the example above, it will be returned directly.

It won't be serialized with a model, etc.

这相当于：

我们曾经通过它向 `TestClient` 发出请求。

/// tip

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

///

/// warning

如果您的应用程序依赖于生命周期事件， `AsyncClient` 将不会触发这些事件。为了确保它们被触发，请使用 <a href="https://github.com/florimondmanca/asgi-lifespan#usage" class="external-link" target="_blank">florimondmanca/asgi-lifespan</a> 中的 `LifespanManager` 。
