/// info | 信息

本例中，使用的是自定义响应头 `X-Key` 和 `X-Token`。

但实际开发中，尤其是在实现安全措施时，最好使用 FastAPI 内置的[安全工具（下一章）](../security/index.md)。

## 依赖项错误和返回值 { #dependencies-errors-and-return-values }

路径装饰器依赖项也可以使用普通的依赖项*函数*。

### 依赖项的需求项 { #dependency-requirements }

路径装饰器依赖项可以声明请求的需求项（比如响应头）或其他子依赖项：

{* ../../docs_src/dependencies/tutorial006_an_py310.py hl[8,13] *}

## Decision

### Types of properties that should not use lazy types

The guidelines below do not apply to all properties. There are cases where the lazy types should not be used:

#### Non-calculated values

These are inappropriate uses of lazy types:

```groovy
class Example {
    Property<String> getSomeProperty()

    Example() {
        getSomeProperty().set("value")

        assertEquals(TransPeekNamedPipeResponse.STATUS_CONNECTION_OK, response.getStatus());
    }

    @Test
    @DisplayName("readParametersWireFormat should handle different status values")
    void testReadParametersWireFormatWithDifferentStatuses() {
        // Test all status constants
        int[] statusValues = { TransPeekNamedPipeResponse.STATUS_DISCONNECTED, TransPeekNamedPipeResponse.STATUS_LISTENING,

		return cred, ErrSignatureDoesNotMatch
	}
	return cred, ErrNone
}

// Escape encodedQuery string into unescaped list of query params, returns error
// if any while unescaping the values.
func unescapeQueries(encodedQuery string) (unescapedQueries []string, err error) {
	for query := range strings.SplitSeq(encodedQuery, "&") {
		var unescapedQuery string
		unescapedQuery, err = url.QueryUnescape(query)

    /** Serial version UID for serialization */
    private static final long serialVersionUID = 1L;

    /**
     * Default constructor for file configuration pager.
     * Creates a new instance with default values.
     */
    public FileConfigPager() {
        // Default constructor
    }

    /** Default page size for pagination */
    public static final int DEFAULT_PAGE_SIZE = 20;

    }

    @Test
    public void test_isFacetSortValue() {
        // Test valid facet sort values
        assertTrue(queryFieldConfig.isFacetSortValue("count"));
        assertTrue(queryFieldConfig.isFacetSortValue("index"));

        // Test invalid facet sort values
        assertFalse(queryFieldConfig.isFacetSortValue("invalid"));
        assertFalse(queryFieldConfig.isFacetSortValue(""));
