### 2 단계: `FastAPI` "인스턴스" 생성 { #step-2-create-a-fastapi-instance }

{* ../../docs_src/first_steps/tutorial001_py310.py hl[3] *}

여기에서 `app` 변수는 `FastAPI` 클래스의 "인스턴스"가 됩니다.

이것은 여러분의 모든 API를 생성하기 위한 상호작용의 주요 지점이 될 것입니다.

### 3 단계: *경로 처리* 생성 { #step-3-create-a-path-operation }

#### 경로 { #path }

여기서 "경로"는 첫 번째 `/`부터 시작하는 URL의 뒷부분을 의미합니다.

Pero es la forma más sencilla de enfocarse en el lado del servidor de WebSockets y tener un ejemplo funcional:

{* ../../docs_src/websockets_/tutorial001_py310.py hl[2,6:38,41:43] *}

## Crear un `websocket` { #create-a-websocket }

En tu aplicación de **FastAPI**, crea un `websocket`:

{* ../../docs_src/websockets_/tutorial001_py310.py hl[1,46:47] *}

* 它可以对该**响应**做一些事情或者执行任何需要的代码。
* 然后它返回这个**响应**。

/// note | 技术细节

如果你有使用 `yield` 的依赖，依赖中的退出代码会在中间件之后运行。

如果有任何后台任务（会在[后台任务](background-tasks.md)一节中介绍，你稍后会看到），它们会在所有中间件之后运行。

///

## 创建中间件 { #create-a-middleware }

要创建中间件，你可以在函数的顶部使用装饰器 `@app.middleware("http")`。

中间件函数会接收：

* `request`。
* 一个函数 `call_next`，它会把 `request` 作为参数接收。
    * 这个函数会把 `request` 传递给相应的*路径操作*。
    * 然后它返回由相应*路径操作*生成的 `response`。

     * <p>
     * Determining the transitive deps of a dependency which has been resolved as
     * non-transitive is difficult because the process of resolving removes the
     * transitive deps. To sidestep this issue, we create a configuration per
     * direct dependency version. This specially named and unique configuration
     * will contain all of the transitive dependencies of this particular

test the deployment using the MinIO Console, an embedded web-based object browser built into MinIO Server. Point a web browser running on the host machine to <http://127.0.0.1:9000> and log in with the root credentials. You can use the Browser to create buckets, upload objects, and browse the contents of the MinIO server. You can also connect using any S3-compatible tool, such as the MinIO Client `mc` commandline tool. See [Test using MinIO Client `mc`](#test-using-minio-client-mc) for more information...
