Você pode instalar todas essas dependências com `pip install fastapi[all]`.

    "itsdangerous >=1.1.0",
    # For Starlette's schema generation, would not be used with FastAPI
    "pyyaml >=5.3.1",
    # For UJSONResponse
    "ujson >=4.0.1,!=4.0.2,!=4.1.0,!=4.2.0,!=4.3.0,!=5.0.0,!=5.1.0",

Por exemplo, vamos supor que você queira utilizar o <a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a>, mas com algumas configurações personalizadas que não estão incluídas na classe `ORJSONResponse`.

Vamos supor também que você queira retornar um JSON indentado e formatado, então você quer utilizar a opção `orjson.OPT_INDENT_2` do orjson.

Takes some data and returns an `application/json` encoded response.

This is the default response used in **FastAPI**, as you read above.

### `ORJSONResponse`

A fast alternative JSON response using <a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a>, as you read above.

/// info

This requires installing `orjson` for example with `pip install orjson`.

///

### `UJSONResponse`

### `JSONResponse`

データを受け取り、 `application/json` としてエンコードされたレスポンスを返します。

上で読んだように、**FastAPI** のデフォルトのレスポンスとして利用されます。

### `ORJSONResponse`

上で読んだように、<a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a>を使った、高速な代替のJSONレスポンスです。

### `UJSONResponse`

<a href="https://github.com/ultrajson/ultrajson" class="external-link" target="_blank">`ujson`</a>を使った、代替のJSONレスポンスです。

/// warning | "注意"

Nehmen wir zum Beispiel an, dass Sie <a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a> verwenden möchten, aber mit einigen benutzerdefinierten Einstellungen, die in der enthaltenen `ORJSONResponse`-Klasse nicht verwendet werden.

Sie möchten etwa, dass Ihre Response eingerücktes und formatiertes JSON zurückgibt. Dafür möchten Sie die orjson-Option `orjson.OPT_INDENT_2` verwenden.
