assertTrue(laterAge >= 200, "Age should increase after delay");
    }

    @Test
    public void testKeyAgeNonExistent() {
        assertEquals(-1, keyManager.getKeyAge("non-existent"), "Non-existent key should return -1 for age");
    }

    @Test
    public void testConfigureKeyRotation() {
        // Test that configuration doesn't throw
        keyManager.configureKeyRotation(60000);

And it has the same shape and structure that all your *path operation functions* have.

You can think of it as a *path operation function* without the "decorator" (without the `@app.get("/some-path")`).

And it can return anything you want.

In this case, this dependency expects:

* An optional query parameter `q` that is a `str`.
* An optional query parameter `skip` that is an `int`, and by default is `0`.

{* ../../docs_src/path_params/tutorial005_py310.py hl[20] *}

/// tip | 提示

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

///

#### 返回枚举成员 { #return-enumeration-members }

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成员。

返回给客户端之前，会把枚举成员转换为对应的值（本例中为字符串）：

{* ../../docs_src/path_params/tutorial005_py310.py hl[18,21,23] *}

客户端中的 JSON 响应如下：

```JSON

    ```kotlin
      override fun intercept(chain: Interceptor.Chain): Response {
        chain.call().tag(MyAnalyticsTag::class) {
          MyAnalyticsTag(...)
        }

        return chain.proceed(chain.request())
      }
    ```

 *  New: Support request bodies on HTTP/1.1 connection upgrades.
 *  New: `EventListener.plus()` makes it easier to observe events in multiple listeners.

        NodeStatusRequest spyRequest = spy(nodeStatusRequest);
        doAnswer(invocation -> {
            // Verify hexCode is 0 during the call
            assertEquals(0x00, mockName.hexCode);
            return 40;
        }).when(spyRequest).writeQuestionSectionWireFormat(any(byte[].class), anyInt());

        // Act
        spyRequest.writeBodyWireFormat(dst, 0);

        // Assert

        response.setHeaders(headers);

        String firstValue = response.getHeaderValue("Accept");

        assertEquals("application/json", firstValue); // Should return first value
    }

    @Test
    public void testContentCache() {
        CurlResponse response = new CurlResponse();
        byte[] data = "test content".getBytes();

```

### Exception Handling
```java
import org.codelibs.core.exception.*;

// Runtime exception wrappers eliminate try-catch boilerplate
try {
    // Code that might throw checked exceptions
    return ClassUtil.newInstance(className); // Wraps checked exceptions automatically
} catch (ClassNotFoundRuntimeException e) {
    // Handle the wrapped exception
    logger.error("Class not found: " + className, e);
}
```

Now the delete marker becomes the current version of the object. GET requests by default always retrieve the latest stored version. So performing a simple GET object request when the current version is a delete marker would return `404` `The specified key does not exist` as shown below:

여러분은 타입이 있는 표준 Python을 다음과 같이 작성합니다:

```Python
from datetime import date

from pydantic import BaseModel

# 변수를 str로 선언합니다
# 그리고 함수 내부에서 편집기 지원을 받습니다
def main(user_id: str):
    return user_id


# Pydantic 모델
class User(BaseModel):
    id: int
    name: str
    joined: date
```

그 다음 다음과 같이 사용할 수 있습니다:
