 *  Fix: Improve recovery from failed routes.
 *  Fix: Accommodate tunneling proxies that close the connection after an auth
    challenge.
 *  Fix: Use the proxy authenticator when authenticating HTTP proxies. This
    regression was introduced in OkHttp 3.0.
 *  Fix: Fail fast if network interceptors transform the response body such that
    closing it doesn't also close the underlying stream. We had a bug where

     *

# yieldを持つ依存関係

FastAPIは、いくつかの<abbr title='時々"exit"、"cleanup"、"teardown"、"close"、"context managers"、 ...のように呼ばれる'>終了後の追加のステップ</abbr>を行う依存関係をサポートしています。

これを行うには、`return`の代わりに`yield`を使い、その後に追加のステップを書きます。

/// tip | 豆知識

`yield`は必ず一度だけ使用するようにしてください。

///

/// info | 情報

これを動作させるには、**Python 3.7** 以上を使用するか、**Python 3.6** では"backports"をインストールする必要があります:

```
pip install async-exit-stack async-generator
```

        ObjectInputStream ois = new ObjectInputStream(bais);
        CrawlerSystemException deserialized = (CrawlerSystemException) ois.readObject();
        ois.close();

        // Verify
        assertNotNull(deserialized);
