如果用戶端請求 `http://example.com/items/foo`（`item_id` 為 `"foo"`），會收到 200 的 HTTP 狀態碼，以及以下 JSON 回應：

```JSON
{
  "item": "The Foo Wrestlers"
}
```

但如果用戶端請求 `http://example.com/items/bar`（不存在的 `item_id` `"bar"`），會收到 404（"not found"）的 HTTP 狀態碼，以及以下 JSON 回應：

```JSON
{
  "detail": "Item not found"
}
```

/// tip

在 raise 一個 `HTTPException` 時，你可以將任何可轉為 JSON 的值作為 `detail` 參數，不只限於 `str`。

## Returning a custom `Response` { #returning-a-custom-response }

The example above shows all the parts you need, but it's not very useful yet, as you could have just returned the `item` directly, and **FastAPI** would put it in a `JSONResponse` for you, converting it to a `dict`, etc. All that by default.

Now, let's see how you could use that to return a custom response.

## TypeScript SDK を作成する { #create-a-typescript-sdk }

まずは簡単な FastAPI アプリから始めます:

{* ../../docs_src/generate_clients/tutorial001_py310.py hl[7:9,12:13,16:17,21] *}

ここで、*path operation* はリクエストとレスポンスのペイロードに使用するモデルを定義しており、`Item` と `ResponseMessage` を使っています。

### API ドキュメント { #api-docs }

`/docs` に移動すると、リクエストで送信・レスポンスで受信するデータの**スキーマ**が表示されます:

<img src="/img/tutorial/generate-clients/image01.png">

これらのスキーマは、アプリ内でモデルとして宣言されているため表示されます。

        try (InputStream stream = cache.getInputStream()) {
            byte[] buffer = new byte[1024];
            int bytesRead = stream.read(buffer);
            byte[] result = new byte[bytesRead];
            System.arraycopy(buffer, 0, result, 0, bytesRead);
            assertArrayEquals(originalData, result);
        }
    }

    @Test
    public void testFileBasedCacheConstructor() throws IOException {
