 * is only meant as a utility for developers that want to employ the settings builder outside of the Maven build system,

## Forbid Extra Query Parameters { #forbid-extra-query-parameters }

In some special use cases (probably not very common), you might want to **restrict** the query parameters that you want to receive.

You can use Pydantic's model configuration to `forbid` any `extra` fields:

{* ../../docs_src/query_param_models/tutorial002_an_py310.py hl[10] *}

请注意，测试函数现在用的是 `async def`，而不是像以前使用 `TestClient` 时那样只是 `def` 。

///

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/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

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

///

## Forbid Extra Headers { #forbid-extra-headers }

In some special use cases (probably not very common), you might want to **restrict** the headers that you want to receive.

You can use Pydantic's model configuration to `forbid` any `extra` fields:

{* ../../docs_src/header_param_models/tutorial002_an_py310.py hl[10] *}

{* ../../docs_src/bigger_applications/app_an_py39/internal/admin.py hl[3] title["app/internal/admin.py"] *}

But we still want to set a custom `prefix` when including the `APIRouter` so that all its *path operations* start with `/admin`, we want to secure it with the `dependencies` we already have for this project, and we want to include `tags` and `responses`.
