/// warning

如果您正在使用`--reload`选项，请记住删除它。

 `--reload` 选项消耗更多资源，并且更不稳定。

 它在**开发**期间有很大帮助，但您**不应该**在**生产环境**中使用它。

Cada programa de servidor ASGI alternativo teria um comando semelhante, você pode ler mais na documentação respectiva.

/// warning | "Aviso"

Uvicorn e outros servidores suportam a opção `--reload` que é útil durante o desenvolvimento.

A opção `--reload` consome muito mais recursos, é mais instável, etc.

Ela ajuda muito durante o **desenvolvimento**, mas você **não deve** usá-la em **produção**.

## Conceitos de Implantação

```Python hl_lines="48-52"
{!../../docs_src/websockets/tutorial001.py!}
```

您可以接收和发送二进制、文本和 JSON 数据。

## 尝试一下

如果您的文件名为 `main.py`，请使用以下命令运行应用程序：

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

在浏览器中打开 <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a>。

	}

	return pReader, opts, nil
}

// Reload updates config by reloading remote tier config from config store.
func (config *TierConfigMgr) Reload(ctx context.Context, objAPI ObjectLayer) error {
	newConfig, err := loadTierConfig(ctx, objAPI)

	config.Lock()
	defer config.Unlock()

	switch err {
	case nil:
		break
	case errConfigNotFound: // nothing to reload

# 最初のステップ

最もシンプルなFastAPIファイルは以下のようになります:

これを`main.py`にコピーします。

ライブサーバーを実行します:
