# Dependências em decoradores de operações de rota { #dependencies-in-path-operation-decorators }

Em alguns casos você não precisa necessariamente do valor de retorno de uma dependência dentro de uma *função de operação de rota*.

Ou a dependência não retorna nenhum valor.

Mas você ainda precisa que ela seja executada/resolvida.

# 路徑操作裝飾器中的依賴 { #dependencies-in-path-operation-decorators }

有時在你的路徑操作函式中，其實不需要某個依賴的回傳值。

或是該依賴根本沒有回傳值。

但你仍需要它被執行／解析。

這種情況下，你可以不在路徑操作函式的參數上使用 `Depends`，而是在路徑操作裝飾器加入一個 `dependencies` 的 `list`。

## 在路徑操作裝飾器加入 `dependencies` { #add-dependencies-to-the-path-operation-decorator }

路徑操作裝飾器可接受一個可選參數 `dependencies`。

它應該是由 `Depends()` 組成的 `list`：

{* ../../docs_src/dependencies/tutorial006_an_py310.py hl[19] *}

     * @param path the path to list
     * @return A stream of file names. No path information is included.
     */
    public Stream<String> listFiles(String ref, String path) {
        return runCommand("git", "ls-tree", "--name-only", "-r", ref, path).lines();
    }

        // When
        Trans2QueryPathInformation trans = new Trans2QueryPathInformation(filename, informationLevel);

        // Then
        assertEquals(filename, trans.path, "The path should be set correctly.");
        assertEquals(ServerMessageBlock.SMB_COM_TRANSACTION2, trans.command, "The command should be SMB_COM_TRANSACTION2.");

		// with the approach we took for returning first ip from multiple
		// params.
		if match := forRegex.FindStringSubmatch(proto); len(match) > 1 {
			if match = protoRegex.FindStringSubmatch(match[2]); len(match) > 1 {
				scheme = strings.ToLower(match[2])
			}
		}
	}

	return scheme
}

// GetSourceIPFromHeaders retrieves the IP from the X-Forwarded-For, X-Real-IP

			erasureDisks[i] = nil
		}
		return erasureDisks
	}
	z.serverPools[0].erasureDisksMu.Unlock()

	t.Run("if-none-match with read quorum failure", func(t *testing.T) {
		// Test Case 1: if-none-match (create only if doesn't exist)
		// With if-none-match: *, this should only succeed if object doesn't exist.
		// Since read quorum fails, we can't determine if object exists.
		opts := ObjectOptions{

### Preferred translations / glossary

Use the following preferred translations when they apply in documentation prose:

- request (HTTP): リクエスト
- response (HTTP): レスポンス
- path operation: path operation (do not translate)

### `///` admonitions

1) Keep the admonition keyword in English (do not translate `note`, `tip`, etc.).
2) If a title is present, prefer these canonical titles:

- `/// note | 備考`

    //                                                                           =========
