本章学习如何使用其它中间件。

## 添加 ASGI 中间件

因为 **FastAPI** 基于 Starlette，且执行 <abbr title="Asynchronous Server Gateway Interface，异步服务器网关界面">ASGI</abbr> 规范，所以可以使用任意 ASGI 中间件。

中间件不必是专为 FastAPI 或 Starlette 定制的，只要遵循 ASGI 规范即可。

总之，ASGI 中间件是类，并把 ASGI 应用作为第一个参数。

因此，有些第三方 ASGI 中间件的文档推荐以如下方式使用中间件：

```Python

   * cache then this is the timestamp of the original request.

  @get:JvmName("sentRequestAtMillis") val sentRequestAtMillis: Long,
  /**
   * Returns a [timestamp][System.currentTimeMillis] taken immediately after OkHttp
   * received this response's headers from the network. If this response is being served from the

	// is skipped.

	if s.withEtcdBackend && etcdServer == "" {
		c.Skip("Skipping etcd backend IAM test as no etcd server is configured.")
