class HTTPAuthorizationCredentials(BaseModel):
    """
    The HTTP authorization credentials in the result of using `HTTPBearer` or
    `HTTPDigest` in a dependency.

    The HTTP authorization header value is split by the first space.

    The first part is the `scheme`, the second part is the `credentials`.

    For example, in an HTTP Bearer token scheme, the client will send a header
    like:

    ```

```

You will see the automatic interactive API documentation (provided by <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Swagger UI</a>):

        client.get("/items/portal-gun")
    assert (
        exc_info.value.args[0] == "The portal gun is too dangerous to be owned by Rick"
    )

# Generate Clients

As **FastAPI** is based on the OpenAPI specification, you get automatic compatibility with many tools, including the automatic API docs (provided by Swagger UI).

One particular advantage that is not necessarily obvious is that you can **generate clients** (sometimes called <abbr title="Software Development Kits">**SDKs**</abbr> ) for your API, for many different **programming languages**.

## OpenAPI Client Generators

) -> ModelField:
    if PYDANTIC_V2:
        return field
    # cloned_types caches already cloned types to support recursive models and improve
    # performance by avoiding unnecessary cloning
    if cloned_types is None:
        cloned_types = _CLONED_TYPES_CACHE

    original_type = field.type_
    if is_dataclass(original_type) and hasattr(original_type, "__pydantic_model__"):

The main thing you need to run a **FastAPI** application (or any other ASGI application) in a remote server machine is an ASGI server program like **Uvicorn**, this is the one that comes by default in the `fastapi` command.

There are several alternatives, including:

* <a href="https://www.uvicorn.org/" class="external-link" target="_blank">Uvicorn</a>: a high performance ASGI server.

!!! info
    To use `TestClient`, first install <a href="https://www.python-httpx.org" class="external-link" target="_blank">`httpx`</a>.

    E.g. `pip install httpx`.

Import `TestClient`.

Create a `TestClient` by passing your **FastAPI** application to it.

Create functions with a name that starts with `test_` (this is standard `pytest` conventions).

Use the `TestClient` object the same way as you do with `httpx`.

* **Intuicyjność**: Wspaniałe wsparcie dla edytorów kodu. Dostępne wszędzie <abbr title="znane jako auto-complete, autocompletion, IntelliSense">automatyczne uzupełnianie</abbr> kodu. Krótszy czas debugowania.
* **Łatwość**: Zaprojektowany by być prosty i łatwy do nauczenia. Mniej czasu spędzonego na czytanie dokumentacji.
* **Kompaktowość**: Minimalizacja powtarzającego się kodu. Wiele funkcjonalności dla każdej deklaracji parametru. Mniej błędów.

!!! tip
    但是依然建议你使用上面提到的主意，使用多个类而不是这些参数。

    这是因为即使使用 `response_model_include` 或 `response_model_exclude` 来省略某些属性，在应用程序的 OpenAPI 定义（和文档）中生成的 JSON Schema 仍将是完整的模型。

    这也适用于作用类似的 `response_model_by_alias`。

```Python hl_lines="31  37"
{!../../../docs_src/response_model/tutorial005.py!}
```

!!! tip
    `{"name", "description"}` 语法创建一个具有这两个值的 `set`。

    等同于 `set(["name", "description"])`。

    それでも、これらのパラメータではなく、複数のクラスを使用して、上記のようなアイデアを使うことをおすすめします。

    これは`response_model_include`や`response_mode_exclude`を使用していくつかの属性を省略しても、アプリケーションのOpenAPI（とドキュメント）で生成されたJSON Schemaが完全なモデルになるからです。

    同様に動作する`response_model_by_alias`にも当てはまります。

```Python hl_lines="31 37"
{!../../../docs_src/response_model/tutorial005.py!}
```

!!! tip "豆知識"
    `{"name", "description"}`の構文はこれら２つの値をもつ`set`を作成します。
