Cache Events are exposed via the EventListener API.  Typical scenarios are below.

### Cache Hit

In the ideal scenario the cache can fulfill the request without any conditional call to the network.
This will skip the normal events such as DNS, connecting to the network, and downloading the response body.

As recommended by the HTTP RFC the max age of a document is defaulted to 10% of the

## The normal **FastAPI** app { #the-normal-fastapi-app }

Let's first see how the normal API app would look like before adding the callback.

It will have a *path operation* that will receive an `Invoice` body, and a query parameter `callback_url` that will contain the URL for the callback.

This part is pretty normal, most of the code is probably already familiar to you:

        }
        Path normal = Paths.get(javahome.getValue()).normalize();
        if (Files.exists(normal)) {
            jtc.setJavaHome(Paths.get(javahome.getValue()).normalize().toString());
        } else {
            throw new MisconfiguredToolchainException(
                    "Non-existing JDK home configuration at " + normal.toAbsolutePath());
        }

        return jtc;
    }

# 擴充 OpenAPI { #extending-openapi }

有些情況你可能需要修改自動產生的 OpenAPI 結構（schema）。

本章將示範如何做。

## 一般流程 { #the-normal-process }

一般（預設）的流程如下。

`FastAPI` 應用程式（實例）有一個 `.openapi()` 方法，會回傳 OpenAPI 結構。

在建立應用物件時，會同時註冊一個 `/openapi.json`（或你在 `openapi_url` 設定的路徑）的路徑操作（path operation）。

這個路徑只會回傳一個 JSON 回應，內容就是應用的 `.openapi()` 方法結果。

預設情況下，`.openapi()` 會先檢查 `.openapi_schema` 屬性是否已有內容，有的話就直接回傳。
