Let's say that now the file `main.py` with your **FastAPI** app has some other **path operations**.

It has a `GET` operation that could return an error.

It has a `POST` operation that could return several errors.

Both *path operations* require an `X-Token` header.

Припустимо, що тепер файл `main.py` із Вашим **FastAPI**-застосунком містить додаткові операції шляху (**path operations**).

Він має `GET`-операцію, яка може повертати помилку.

Він має `POST`-операцію, яка може повертати кілька помилок.

Обидві операції шляху вимагають заголовок `X-Token`.

你可以在 **FastAPI** 应用中使用 `CORSMiddleware` 来配置它。

* 导入 `CORSMiddleware`。
* 创建一个允许的源列表（由字符串组成）。
* 将其作为「中间件」添加到你的 **FastAPI** 应用中。

你也可以指定后端是否允许：

* 凭证（授权 headers，Cookies 等）。
* 特定的 HTTP 方法（`POST`，`PUT`）或者使用通配符 `"*"` 允许所有方法。
* 特定的 HTTP headers 或者使用通配符 `"*"` 允许所有 headers。

{* ../../docs_src/cors/tutorial001.py hl[2,6:11,13:19] *}

默认情况下，这个 `CORSMiddleware` 实现所使用的默认参数较为保守，所以你需要显式地启用特定的源、方法或者 headers，以便浏览器能够在跨域上下文中使用它们。
