The same way, you can define logic (code) that should be executed when the application is **shutting down**. In this case, this code will be executed **once**, **after** having handled possibly **many requests**.

  // Optional: confirm that your app made the HTTP requests you were expecting.
  RecordedRequest request1 = server.takeRequest();
  assertEquals("/v1/chat/messages/", request1.getUrl().encodedPath());
  assertNotNull(request1.getHeaders().get("Authorization"));

  RecordedRequest request2 = server.takeRequest();
  assertEquals("/v1/chat/messages/2", request2.getUrl().encodedPath());

  RecordedRequest request3 = server.takeRequest();

但在某些特定情况下，还是需要提取 `Request` 对象。

## 直接使用 `Request` 对象

假设要在*路径操作函数*中获取客户端 IP 地址和主机。

此时，需要直接访问请求。

{* ../../docs_src/using_request_directly/tutorial001.py hl[1,7:8] *}

把*路径操作函数*的参数类型声明为 `Request`，**FastAPI** 就能把 `Request` 传递到参数里。

/// tip | 提示

注意，本例除了声明请求参数之外，还声明了路径参数。

因此，能够提取、验证路径参数、并转换为指定类型，还可以用 OpenAPI 注释。

同样，您也可以正常声明其它参数，而且还可以提取 `Request`。
