 *  Fix: Change `Headers.toString()` to redact authorization and cookie headers.
 *  Fix: Don't do DNS to get the hostname for `RecordedRequest.requestUrl`. This was doing a DNS
    lookup for the local hostname, but we really just wanted the `Host` header.

而且你还可以根据你的需要响应不同的对象，比如常用的 `dict`，数据库model等。

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。

async def get_current_user(token: Annotated[str, Depends(oauth2_scheme)]):
    credentials_exception = HTTPException(
        status_code=status.HTTP_401_UNAUTHORIZED,
        detail="Could not validate credentials",
        headers={"WWW-Authenticate": "Bearer"},
    )
    try:
        payload = jwt.decode(token, SECRET_KEY, algorithms=[ALGORITHM])
        username = payload.get("sub")
        if username is None:

  val request = createRequest()

  try {
    val response = client!!.newCall(request).execute()
    if (showHeaders) {
      println(StatusLine.get(response))
      val headers = response.headers
      for ((name, value) in headers) {
        println("$name: $value")
      }
      println()
    }

    // Stream the response to the System.out as it is returned from the server.
    val out = System.out.sink()

```

La buena noticia es que, una vez que estés en Python 3.10, no tendrás que preocuparte por eso, ya que podrás simplemente usar `|` para definir uniones de tipos:

{* ../../docs_src/python_types/tutorial009c_py310.py hl[1,4] *}

Y entonces no tendrás que preocuparte por nombres como `Optional` y `Union`. 😎
