### Modell für Ausgabe-Responsedaten { #model-for-output-response-data }

Wenn Sie mit der Dokumentation interagieren und die <abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr> überprüfen, enthält die JSON-Response den Defaultwert (`null`), obwohl der Code nichts in eines der `description`-Felder geschrieben hat:

用户指南介绍了如何为应用添加[自定义中间件](../tutorial/middleware.md)。

以及如何[使用 `CORSMiddleware` 处理 CORS](../tutorial/cors.md)。

本章学习如何使用其它中间件。

## 添加 ASGI 中间件 { #adding-asgi-middlewares }

因为 **FastAPI** 基于 Starlette，且执行 <abbr title="Asynchronous Server Gateway Interface - 异步服务器网关接口">ASGI</abbr> 规范，所以可以使用任意 ASGI 中间件。

中间件不必是专为 FastAPI 或 Starlette 定制的，只要遵循 ASGI 规范即可。

总之，ASGI 中间件是类，并把 ASGI 应用作为第一个参数。

因此，有些第三方 ASGI 中间件的文档推荐以如下方式使用中间件：

```Python

	configFiles := []string{
		getConfigFile(),
		getConfigFile() + ".deprecated",
		configFile,
	}

	newServerCfg := func() (config.Config, error) {
		// Initialize server config.
		srvCfg := newServerConfig()

		return srvCfg, saveServerConfig(ctx, objAPI, srvCfg)
	}

	var data []byte
	var err error

	cfg := &serverConfigV33{}
	for _, cfgFile := range configFiles {

COMMANDS:
  generate  generate a new batch job definition
  start     start a new batch job
  list, ls  list all current batch jobs
  status    summarize job events on MinIO server in real-time
  describe  describe job definition for a job
```

### Generate a job yaml
```
mc batch generate alias/ replicate
```

### Start the batch job (returns back the JID)
```

    public int getShareAccessHint() {
        return shareAccessHint;
    }

    @Override
    protected int writeBytesWireFormat(byte[] dst, int dstIndex) {
        // Lease break notifications are sent by the server, not written by client
        return 0;
    }

    @Override
    protected int readBytesWireFormat(byte[] buffer, int bufferIndex) throws SMBProtocolDecodingException {
        int start = bufferIndex;

В этом разделе посмотрим, как использовать другие middleware.

## Добавление ASGI middleware { #adding-asgi-middlewares }

Так как **FastAPI** основан на Starlette и реализует спецификацию <abbr title="Asynchronous Server Gateway Interface – Асинхронный шлюзовой интерфейс сервера">ASGI</abbr>, вы можете использовать любое ASGI middleware.

		fmt.Println("AccessKeyID:", v.AccessKeyID)
		fmt.Println("SecretAccessKey:", v.SecretAccessKey)
		fmt.Println("SessionToken:", v.SessionToken)
		return
	}

	// Use generated credentials to authenticate with MinIO server
	minioClient, err := minio.New(stsEndpointURL.Host, opts)
	if err != nil {
		log.Fatalf("Error initializing client: %v", err)
	}

	// Use minIO Client object normally like the regular client.

```

If provided, the auth token parameter is sent as an authorization header.

`MINIO_IDENTITY_PLUGIN_ROLE_POLICY` is a required parameter and can be list of comma separated policy names.

On setting up the plugin, the MinIO server prints the Role ARN to its log. The Role ARN is generated by default based on the given plugin URL. To avoid this and use a configurable value set a unique role ID via `MINIO_IDENTITY_PLUGIN_ROLE_ID`.
