Auf die gleiche Weise können Sie eine `list`e von `Depends` im Parameter `dependencies` des Dekorators definieren (wie in [Abhängigkeiten in Pfadoperation-Dekoratoren](../../tutorial/dependencies/dependencies-in-path-operation-decorators.md) erläutert), Sie könnten auch dort `Security` mit `scopes` verwenden....

現在我們建立一個相依，回傳新的 `config.Settings()`。

{* ../../docs_src/settings/app02_an_py310/main.py hl[6,12:13] *}

/// tip

我們稍後會討論 `@lru_cache`。

現在你可以先把 `get_settings()` 視為一般函式。

///

接著我們可以在*路徑操作函式 (path operation function)* 中將它宣告為相依，並在需要的地方使用它。

### 設定與測試 { #settings-and-testing }

接著，在測試時要提供不同的設定物件會非常容易，只要為 `get_settings` 建立相依覆寫（dependency override）即可：

        @Override
        public int getOpnum() {
            return 0x0f;
        }

        /** Return value from the RPC call. */
        public int retval;
        /** Policy handle for the LSA operation. */
        public rpc.policy_handle handle;
        /** Array of SIDs to lookup. */
        public LsarSidArray sids;
        /** Referenced domain list returned from lookup. */

             * for whatever reason. I copy over the uid here so it appears correct
