**FastAPI** 会自动使用默认的状态码或者使用你在 *路径操作* 中设置的状态码。

## 额外的状态码

如果你想要返回主要状态码之外的状态码，你可以通过直接返回一个 `Response` 来实现，比如 `JSONResponse`，然后直接设置额外的状态码。

例如，假设你想有一个 *路径操作* 能够更新条目，并且更新成功时返回 200 「成功」 的 HTTP 状态码。

但是你也希望它能够接受新的条目。并且当这些条目不存在时，会自动创建并返回 201 「创建」的 HTTP 状态码。

要实现它，导入 `JSONResponse`，然后在其中直接返回你的内容，并将 `status_code` 设置为为你要的值。

编码和表单字段详见 <a href="https://developer.mozilla.org/zh-CN/docs/Web/HTTP/Methods/POST" class="external-link" target="_blank"><abbr title="Mozilla Developer Network">MDN</abbr> Web 文档的 <code>POST</code></a>小节。

/// warning | 警告

可在一个*路径操作*中声明多个 `Form` 参数，但不能同时声明要接收 JSON 的 `Body` 字段。因为此时请求体的编码是 `application/x-www-form-urlencoded`，不是 `application/json`。

这不是 **FastAPI** 的问题，而是 HTTP 协议的规定。

	AmzRequestRoute = "x-amz-request-route"
	AmzRequestToken = "x-amz-request-token"

	AmzFwdStatus                   = "x-amz-fwd-status"

Наприклад, такі адреси вважаються різними джерелами:

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`

Навіть якщо вони всі містять `localhost`, вони мають різні протоколи або порти, що робить їх окремими "джерелами".

## Origin { #origin }

Ein <abbr title="Ursprung">Origin</abbr> ist die Kombination aus Protokoll (`http`, `https`), Domain (`myapp.com`, `localhost`, `localhost.tiangolo.com`) und Port (`80`, `443`, `8080`).

Alle folgenden sind also unterschiedliche Origins:

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`
