!!! note "说明"
    如果你使用不带有任何媒体类型的响应类，FastAPI 认为你的响应没有任何内容，所以不会在生成的OpenAPI文档中记录响应格式。

## 使用 `ORJSONResponse`

例如，如果你需要压榨性能，你可以安装并使用 <a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a> 并将响应设置为 `ORJSONResponse`。

导入你想要使用的 `Response` 类（子类）然后在 *路径操作装饰器* 中声明它。

```Python hl_lines="2 7"
{!../../../docs_src/custom_response/tutorial001b.py!}
```

		{"/./abc/def", "/abc/def"},
		{"abc/.", "abc"},

		// Remove .. elements
		{"abc/def/ghi/../jkl", "abc/def/jkl"},
		{"abc/def/../ghi/../jkl", "abc/jkl"},
		{"abc/def/..", "abc"},
		{"abc/def/../..", "."},
		{"/abc/def/../..", "/"},
		{"abc/def/../../..", ".."},
		{"/abc/def/../../..", "/"},
		{"abc/def/../../../ghi/jkl/../../../mno", "../../mno"},

		// Combinations
		{"abc/./../def", "def"},

## `ORJSONResponse` verwenden

Um beispielsweise noch etwas Leistung herauszuholen, können Sie <a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a> installieren und verwenden, und die Response als `ORJSONResponse` deklarieren.
