因此，你可以重複使用在其他地方已使用過的一般依賴（會回傳值），即使回傳值不會被使用，該依賴仍會被執行：

{* ../../docs_src/dependencies/tutorial006_an_py310.py hl[11,16] *}

## 一組路徑操作的依賴 { #dependencies-for-a-group-of-path-operations }

之後在閱讀如何組織較大的應用程式（[較大型應用程式——多個檔案](../../tutorial/bigger-applications.md)）時，你會學到如何為一組路徑操作宣告一個共同的 `dependencies` 參數。

## 全域依賴 { #global-dependencies }

   */
  static long toNanosSaturated(Duration duration) {
    // Using a try/catch seems lazy, but the catch block will rarely get invoked (except for
    // durations longer than approximately +/- 292 years).
    try {
      return duration.toNanos();
    } catch (ArithmeticException tooBig) {
      return duration.isNegative() ? Long.MIN_VALUE : Long.MAX_VALUE;
    }
  }

Plus tard, en lisant comment structurer des applications plus grandes ([Applications plus grandes - Plusieurs fichiers](../../tutorial/bigger-applications.md)), éventuellement avec plusieurs fichiers, vous apprendrez à déclarer un unique paramètre `dependencies` pour un groupe de *chemins d'accès*.

## Définir des dépendances globales { #global-dependencies }

            f" Please update the response model {type_!r}."
        )

## 2. Install MinIO in Chroot

> **Note:** MinIO community edition is now distributed as source code only. Pre-compiled binaries are no longer provided for new releases.

Build MinIO from source and install it in the chroot directory:

```sh
# Build MinIO from source
go install github.com/minio/minio@latest

# Create the bin directory in your chroot

    @Required
    @Min(0)
    @Max(100)
    @ValidateTypeFailure

    /**
     * Enable or disable search query logging.
     * When enabled, user search queries are logged for analysis.
     */
    @Size(max = 10)
    public String searchLog;

    /**
     * Enable or disable user information tracking.
     * When enabled, user information is stored and tracked.
     */

## Abhängigkeiten für eine Gruppe von *Pfadoperationen* { #dependencies-for-a-group-of-path-operations }

Wenn Sie später lesen, wie Sie größere Anwendungen strukturieren ([Größere Anwendungen – Mehrere Dateien](../../tutorial/bigger-applications.md)), möglicherweise mit mehreren Dateien, lernen Sie, wie Sie einen einzelnen `dependencies`-Parameter für eine Gruppe von *Pfadoperationen* deklarieren.

## Globale Abhängigkeiten { #global-dependencies }

	// Requests sent to the server.
	// If the handler is defined with 0 incoming capacity this will be nil.
	// Channel *must* be closed to signal the end of the stream.
	// If the request context is canceled, the stream will no longer process requests.
	// Requests sent cannot be used any further by the called.
	Requests chan<- []byte

	muxID uint64
	ctx   context.Context
}

// Send a payload to the remote server.

## Exemplo { #example }

Para um exemplos simples, vamos considerar uma estrutura de arquivos semelhante ao descrito em [Aplicações Maiores](../tutorial/bigger-applications.md) e [Testes](../tutorial/testing.md):

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

O arquivo `main.py` teria:
