#### 获取*枚举值*

使用 `model_name.value` 或 `your_enum_member.value` 获取实际的值（本例中为**字符串**）：

```Python hl_lines="20"
{!../../docs_src/path_params/tutorial005.py!}
```

/// tip | "提示"

使用 `ModelName.lenet.value` 也能获取值 `"lenet"`。

#### 返回*枚举元素*

即使嵌套在 JSON 请求体里（例如， `dict`），也可以从*路径操作*返回*枚举元素*。

 * ### Query
 *
 * The query is optional: it can be null, empty, or non-empty. For many HTTP URLs the query string
 * is subdivided into a collection of name-value parameters. This class offers methods to set the
 * query as the single string, or as individual name-value parameters. With name-value parameters
 * the values are optional and names may be repeated.
