Dans ce cas, la fonction gestionnaire de l'événement `startup` initialisera la « base de données » des items (juste un `dict`) avec quelques valeurs.

Vous pouvez ajouter plusieurs fonctions de gestion d'événements.

**FastAPI** 為了方便開發者，將 `starlette.responses` 也提供為 `fastapi.responses`。但大多數可用的回應類型其實直接來自 Starlette。

## 回傳自訂 `Response` { #returning-a-custom-response }

上面的範例展示了所需的各個部分，但目前還不太實用，因為你其實可以直接回傳 `item`，**FastAPI** 就會幫你把它放進 `JSONResponse`，轉成 `dict` 等，這些都是預設行為。

現在來看看如何用它來回傳自訂回應。

假設你想要回傳一個 [XML](https://en.wikipedia.org/wiki/XML) 回應。

你可以把 XML 內容放進一個字串，把它放進 `Response`，然後回傳它：

		}
		buf.WriteString(input.Text())
	}
}

type badLexTest struct {
	input string
	error string
}

var badLexTests = []badLexTest{
	{
		"3 #define foo bar\n",
		"'#' must be first item on line",
	},
	{
		"#ifdef foo\nhello",
		"unclosed #ifdef or #ifndef",
	},
	{
		"#ifndef foo\nhello",
		"unclosed #ifdef or #ifndef",
	},
	{
		"#ifdef foo\nhello\n#else\nbye",

        });
    }
