Pero puedes devolver una `JSONResponse` directamente de tu *operación de path*.

Esto puede ser útil, por ejemplo, para devolver cookies o headers personalizados.

## Devolver una `Response`

De hecho, puedes devolver cualquier `Response` o cualquier subclase de la misma.

/// tip | Consejo

`JSONResponse` en sí misma es una subclase de `Response`.

Find ways to get great performance.

Along with Hug (as Hug is based on Falcon) inspired **FastAPI** to declare a `response` parameter in functions.

Although in FastAPI it's optional, and is used mainly to set headers, cookies, and alternative status codes.

On startup all remote servers must be specified. 
From that individual connections will be spawned to each remote server, 
or incoming requests will be hooked up to the appropriate connection.

To get a connection to a specific server, use `Manager.Connection(host)` to get a connection to the specified host.
From this connection individual requests can be made.

# 直接使用请求

至此，我们已经使用多种类型声明了请求的各种组件。

并从以下对象中提取数据：

* 路径参数
* 请求头
* Cookies
* 等

**FastAPI** 使用这种方式验证数据、转换数据，并自动生成 API 文档。

但有时，我们也需要直接访问 `Request` 对象。

## `Request` 对象的细节

实际上，**FastAPI** 的底层是 **Starlette**，**FastAPI** 只不过是在  **Starlette** 顶层提供了一些工具，所以能直接使用 Starlette 的  <a href="https://www.starlette.io/requests/" class="external-link" target="_blank">`Request`</a> 对象。

With `Form` you can declare the same configurations as with `Body` (and `Query`, `Path`, `Cookie`), including validation, examples, an alias (e.g. `user-name` instead of `username`), etc.

/// info

`Form` is a class that inherits directly from `Body`.

    val cookieManager = CookieManager(null, CookiePolicy.ACCEPT_ORIGINAL_SERVER)
    val cookie = HttpCookie("c", "cookie")
    cookie.domain = server.hostName
    cookie.path = "/"
    val portList = server.port.toString()
    cookie.portlist = portList
    cookieManager.cookieStore.add(server.url("/").toUri(), cookie)
    client =
      client.newBuilder()
        .cookieJar(JavaNetCookieJar(cookieManager))

#                                                     Cookie
#                                                     ------
# The default path of cookie (basically '/' if no context path)
cookie.default.path = /

# The default expire of cookie in seconds e.g. 31556926: one year, 86400: one day
cookie.default.expire = 3600

session.tracking.modes=cookie

Mais vous pouvez retourner une `JSONResponse` directement à partir de vos *opérations de chemin*.

Cela peut être utile, par exemple, pour retourner des en-têtes personnalisés ou des cookies.

## Renvoyer une `Response`

En fait, vous pouvez retourner n'importe quelle `Response` ou n'importe quelle sous-classe de celle-ci.

/// note | "Remarque"

`Form` sınıfıyla tanımlama yaparken `Body`, `Query`, `Path` ve `Cookie` sınıflarında kullandığınız aynı validasyon, örnekler, isimlendirme (örneğin `username` yerine `user-name` kullanımı) ve daha fazla konfigurasyonu kullanabilirsiniz.

/// info | "Bilgi"

OpenAPI define os seguintes esquemas de segurança:

* `apiKey`: uma chave específica de aplicação que pode vir de:
    * Um parâmetro query.
    * Um header.
    * Um cookie.
* `http`: padrão HTTP de sistemas autenticação, incluindo:
    * `bearer`: um header de `Authorization` com valor de `Bearer` adicionado de um token. Isso é herança do OAuth2.
    * HTTP Basic authentication.
