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

	fakeGW                 = net.ParseIP("88.9.9.9")
	fakeIDX                = 0
	fakePrevResultIPConfig = cniv1.IPConfig{
		Interface: &fakeIDX,
		Address: net.IPNet{
			IP: fakeIP,
		},
		Gateway: fakeGW,
	}
)

func TestPushCNIAddEventSucceed(t *testing.T) {
	// Fake out a test HTTP server and use that instead of a real HTTP server over gRPC to validate  req/resp flows

        return null;
    }

    // ===================================================================================
    //                                                                    Property Gateway
    //                                                                    ================
    // -----------------------------------------------------
    //                                       Column Property

        return null;
    }

    // ===================================================================================
    //                                                                    Property Gateway
    //                                                                    ================
    // -----------------------------------------------------
    //                                       Column Property

        return null;
    }

    // ===================================================================================
    //                                                                    Property Gateway
    //                                                                    ================
    // -----------------------------------------------------
    //                                       Column Property

        return null;
    }

    // ===================================================================================
    //                                                                    Property Gateway
    //                                                                    ================
    // -----------------------------------------------------
    //                                       Column Property

        return null;
    }

    // ===================================================================================
    //                                                                    Property Gateway
    //                                                                    ================
    // -----------------------------------------------------
    //                                       Column Property

In this section we'll see how to use other middlewares.

## Adding ASGI middlewares

As **FastAPI** is based on Starlette and implements the <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr> specification, you can use any ASGI middleware.

A middleware doesn't have to be made for FastAPI or Starlette to work, as long as it follows the ASGI spec.
