## 开发 { #development }

当我启动 **FastAPI** 开发的时候，绝大多数部件都已经就位，设计已经定义，需求项和工具也已经准备就绪，相关标准与规范的知识储备也非常清晰而新鲜。

## 未来 { #future }

至此，**FastAPI** 及其理念已经为很多人所用。

对于很多用例，它比以前很多备选方案都更适用。

很多开发者和开发团队已经依赖 **FastAPI** 开发他们的项目（包括我和我的团队）。

但，**FastAPI** 仍有很多改进的余地，也还需要添加更多的功能。

**FastAPI** 前景光明。

# FastAPI Cloud { #fastapi-cloud }

**한 번의 명령**으로 FastAPI 앱을 [FastAPI Cloud](https://fastapicloud.com)에 배포할 수 있습니다. 아직이라면 대기자 명단에 등록해 보세요. 🚀

## 로그인하기 { #login }

먼저 **FastAPI Cloud** 계정이 이미 있는지 확인하세요(대기자 명단에서 초대해 드렸을 거예요 😉).

그다음 로그인합니다:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

## 배포하기 { #deploy }

이제 **한 번의 명령**으로 앱을 배포합니다:

Provided directly by Starlette, but you can import it from `fastapi`:

```python
from fastapi.websockets import WebSocketDisconnect, WebSocketState
```

::: fastapi.websockets.WebSocketDisconnect

When a client disconnects, a `WebSocketDisconnect` exception is raised, you can catch it.

You can import it directly form `fastapi`:

```python
from fastapi import WebSocketDisconnect
```

# 手动运行服务器 { #run-a-server-manually }

## 使用 `fastapi run` 命令 { #use-the-fastapi-run-command }

简而言之，使用 `fastapi run` 来运行您的 FastAPI 应用程序：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> run <u style="text-decoration-style:solid">main.py</u>

  <span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting production server 🚀

             Searching for package file structure from directories

Read more about it in the [FastAPI docs about Response Status Code](https://fastapi.tiangolo.com/tutorial/response-status-code/).

## Example

```python
from fastapi import FastAPI, status

app = FastAPI()


@app.get("/items/", status_code=status.HTTP_418_IM_A_TEAPOT)
def read_items():
    return [{"name": "Plumbus"}, {"name": "Portal Gun"}]
```

```toml
[tool.fastapi]
entrypoint = "backend.main:app"
```

що було б еквівалентно:

```python
from backend.main import app
```

### `fastapi dev` із шляхом { #fastapi-dev-with-path }

Ви також можете передати шлях до файлу в команду `fastapi dev`, і вона вгадає обʼєкт FastAPI app, який слід використовувати:

```console
$ fastapi dev main.py
```

These tests verify that special FastAPI types can be used with Depends() annotations
and that the dependency injection system properly handles them.
