如果你定义了 `response_model`，程序会自动根据`response_model`来过滤和转换你响应的对象。

**FastAPI** 会使用这个 *临时* 响应对象去装在这些cookies信息 (同样还有headers和状态码等信息), 最终会将这些信息和通过`response_model`转化过的数据合并到最终的响应里。

你也可以在depend中定义`Response`参数，并设置cookie和header。

## 直接响应 `Response`

你还可以在直接响应`Response`时直接创建cookies。

你可以参考[Return a Response Directly](response-directly.md){.internal-link target=_blank}来创建response

然后设置Cookies，并返回：

    // Body contains nothing.
    assertThat(response.body.bytes().size).isEqualTo(0)
    assertThat(response.body.contentLength()).isEqualTo(0)

    // Content-Length header doesn't exist in a 204 response.
    assertThat(response.header("content-length")).isNull()
    assertThat(response.code).isEqualTo(204)
    val request = server.takeRequest()
    assertThat(request.requestLine).isEqualTo("GET /foo HTTP/2")
  }

	if err != nil {

	}
	if cap((*z)) >= int(zb0002) {
		(*z) = (*z)[:zb0002]
	} else {

## Language Detection and Selection

### User Interface Language

Fess determines the UI language in this order:

1. **Query parameter**: `?browser_lang=[locale]` (highest priority)
2. **Browser header**: `Accept-Language` header
3. **Fallback**: English (from `fess_label.properties` and `fess_message.properties`)

### Document Language Detection

During crawling and indexing, Fess:

# ========================================================================================
# Framework Default
# =================
# ----------------------------------------------------------
# Lasta Taglib
# ------------
errors.header = <ul class="has-error">
errors.footer = </ul>
errors.prefix = <li><i class="fa fa-exclamation-circle"></i>
errors.suffix = </li>
# ----------------------------------------------------------
# Javax Validator

        when(mockInfo.encode(any(byte[].class), anyInt())).thenReturn(20);
        when(mockInfo.size()).thenReturn(20);
        request.setInfo(mockInfo);

        // Set up header start for offset calculation
        try {
            Method getHeaderStartMethod = ServerMessageBlock2.class.getDeclaredMethod("getHeaderStart");
            getHeaderStartMethod.setAccessible(true);
