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

package auth

import (
	"encoding/json"
	"testing"
	"time"
)

func TestExpToInt64(t *testing.T) {
	testCases := []struct {
		exp             interface{}
		expectedFailure bool
	}{
		{"", true},
		{"-1", true},
		{"1574812326", false},
		{1574812326, false},
		{int64(1574812326), false},
		{int(1574812326), false},
		{uint(1574812326), false},
