## Version 4.9.0

_2020-09-11_

**With this release, `okhttp-tls` no longer depends on Bouncy Castle and doesn't install the
Bouncy Castle security provider.** If you still need it, you can do it yourself:

```
Security.addProvider(BouncyCastleProvider())
```

You will also need to configure this dependency:

```

OpenAPI中所包含的模型里有相同的信息可以用于 **生成客户端代码**。

### 生成一个TypeScript 客户端

现在我们有了带有模型的应用，我们可以为前端生成客户端代码。

#### 安装 `openapi-ts`

您可以使用以下工具在前端代码中安装 `openapi-ts`:

<div class="termy">

```console
$ npm install @hey-api/openapi-ts --save-dev

---> 100%
```

</div>

#### 生成客户端代码

要生成客户端代码，您可以使用现在将要安装的命令行应用程序 `openapi-ts`。

因为它安装在本地项目中，所以您可能无法直接使用此命令，但您可以将其放在 `package.json` 文件中。

它可能看起来是这样的:

{* ../../docs_src/dependencies/tutorial008b_an_py39.py hl[18:22,31] *}

Если вы хотите перехватывать исключения и формировать на их основе пользовательский ответ, создайте [Пользовательский обработчик исключений](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank}.

## Зависимости с `yield` и `except` { #dependencies-with-yield-and-except }

    if: github.ref == 'refs/heads/master' || contains(github.event.pull_request.labels.*.name, 'jdkversions')

    steps:
      - name: Checkout
        uses: actions/checkout@v6

      - name: Install Old JDK 8
        uses: actions/setup-java@v5
        with:
          distribution: 'zulu'
          java-version: 8.0.242

      - name: Configure JDK
        uses: actions/setup-java@v5
        with:

///

{* ../../docs_src/dependencies/tutorial008b_an_py39.py hl[18:22,31] *}

Se você quiser capturar exceções e criar uma resposta personalizada com base nisso, crie um [Manipulador de Exceções Customizado](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank}.

## Dependências com `yield` e `except` { #dependencies-with-yield-and-except }

///

{* ../../docs_src/dependencies/tutorial008b_an_py39.py hl[18:22,31] *}

If you want to catch exceptions and create a custom response based on that, create a [Custom Exception Handler](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank}.

## Dependencies with `yield` and `except` { #dependencies-with-yield-and-except }

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。

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
```
