        // Test setting a custom instance
        LogStream.setInstance(testStream);

        // Write something to verify it uses our test stream

/// note | 技術細節

你也可以使用 `from starlette.responses import JSONResponse`。

**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。
