### Crear el objeto `Settings` { #create-the-settings-object }

Importa `BaseSettings` de Pydantic y crea una sub-clase, muy similar a un modelo de Pydantic.

## Crie um SDK em TypeScript { #create-a-typescript-sdk }

Vamos começar com uma aplicação FastAPI simples:

{* ../../docs_src/generate_clients/tutorial001_py310.py hl[7:9,12:13,16:17,21] *}

因為第一個會被優先使用（路徑先匹配到）。

## 預先定義的值 { #predefined-values }

如果你有一個接收「路徑參數」的「路徑操作」，但你希望可用的「路徑參數」值是預先定義好的，你可以使用標準的 Python <abbr title="Enumeration - 列舉">`Enum`</abbr>。

### 建立 `Enum` 類別 { #create-an-enum-class }

匯入 `Enum` 並建立一個同時繼承自 `str` 與 `Enum` 的子類別。

繼承自 `str` 之後，API 文件就能知道這些值的型別必須是 `string`，並能正確地呈現。

然後建立具有固定值的類別屬性，這些就是可用的有效值：

{* ../../docs_src/path_params/tutorial005_py310.py hl[1,6:9] *}

        File shaFile = getShaFile(jarName);
        if (shaFile.exists() == false) {
            throw new GradleException("Missing SHA for " + jarName + ". Run \"gradle updateSHAs\" to create them");
        }

        // TODO: shouldn't have to trim, sha files should not have trailing newline
        byte[] fileBytes = Files.readAllBytes(shaFile.toPath());

	dirAbs, err := filepath.Abs(dir)
	if err != nil {
		return nil, err
	}
	err = mkdirAllIgnorePerm(dirAbs)
	if err != nil {
		return nil, fmt.Errorf("unable to create the directory `%s`: %w", dirAbs, err)
	}

	return &ConfigDir{path: dirAbs}, nil
}

func buildServerCtxt(ctx *cli.Context, ctxt *serverCtxt) (err error) {
	// Get "json" flag from command line argument and

    private static String webConfigId;

    @BeforeAll
    protected static void initAll() {
        RestAssured.baseURI = getFessUrl();
        settingTestToken();

        // create and execute a web crawler
        createWebConfig();
        logger.info("WebConfig is created");
        refresh();
        webConfigId = getWebConfigIds(NAME_PREFIX).get(0);

        createJob();

        when(mockTreeHandle.send(any(Smb2WriteRequest.class), any())).thenReturn(mockWriteResponse);
        when(mockWriteResponse.getCount()).thenReturn(8);

        // Create output stream in append mode - note the append flag sets initial fp to 100
        outputStream = new SmbFileOutputStream(mockFile, mockTreeHandle, mockFileHandle,

        }

        @Test
        @DisplayName("Should handle multiple configurations")
        void testMultipleConfigurations() throws SMBProtocolDecodingException {
            // Given - create multiple configurations
            Configuration config1 = mock(Configuration.class);
            Configuration config2 = mock(Configuration.class);

            Smb2LockResponse response1 = new Smb2LockResponse(config1);

### Crear una clase `Enum` { #create-an-enum-class }

Importa `Enum` y crea una subclase que herede de `str` y de `Enum`.
