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.

Running this race over home WiFi shows the Times (`0002`) completes just slightly sooner than the Post (`0001`):

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（Authorization 请求头、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 请求头或者使用通配符 `"*"` 允许所有请求头。

{* ../../docs_src/cors/tutorial001_py310.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。
