worked everywhere that I know of except for one place: when running the GWT
    util.concurrent tests under Guava.

    The problem is that GWT responds poorly to two .gwt.xml files in the same
    Java package; see
    https://groups.google.com/g/google-web-toolkit-contributors/c/CqYH59Dt_rQ/m/uVGW1QdUsXUJ
    for details.

    The summary is that it ignores one file in favor of the other.

Hiding the documentation just makes it more difficult to understand how to interact with your API, and could make it more difficult for you to debug it in production. It could be considered simply a form of <a href="https://en.wikipedia.org/wiki/Security_through_obscurity" class="external-link" target="_blank">Security through obscurity</a>.

If you want to secure your API, there are several better things you can do, for example:

{* ../../docs_src/query_param_models/tutorial002_an_py310.py hl[10] *}

如果客戶端嘗試在**查詢參數**中發送一些**額外的**資料，他們將會收到一個**錯誤**回應。

例如，如果客戶端嘗試發送一個值為 `plumbus` 的 `tool` 查詢參數，如：

```http
https://example.com/items/?limit=10&tool=plumbus
```

他們將收到一個**錯誤**回應，告訴他們查詢參數 `tool` 是不允許的：

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["query", "tool"],

        url = "http://example.com/";
        exp = "http://example.com/";
        assertEquals(exp, transformer.decodeUrlAsName(url, false));

        url = "http://example.com/index.html";
        exp = "http://example.com/index.html";
        assertEquals(exp, transformer.decodeUrlAsName(url, false));

        url = "http://example.com/" + encodeUrl("テスト ") + ".html";

Así que, la línea:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

no se ejecutará.

## Запуск вашего кода с помощью отладчика

В таких случаях обычно возвращается **HTTP-код статуса ответа** в диапазоне **400** (от 400 до 499).

Они похожи на двухсотые HTTP статус-коды (от 200 до 299), которые означают, что запрос обработан успешно.

Четырёхсотые статус-коды означают, что ошибка произошла по вине клиента.

Помните ли ошибки **"404 Not Found "** (и шутки) ?

## Использование `HTTPException`

Для возврата клиенту HTTP-ответов с ошибками используется `HTTPException`.
