<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

pkg image/color, type Gray16 struct
pkg image/color, type Gray16 struct, Y uint16
pkg image/color, type Model interface { Convert }
pkg image/color, type Model interface, Convert(Color) Color
pkg image/color, type NRGBA struct
pkg image/color, type NRGBA struct, A uint8

pkg image/color, type NRGBA struct, G uint8

```console
$ pip install python-multipart
```

因為 OAuth2 會以「form data」傳送 `username` 與 `password`。

///

用以下指令執行範例：

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

## 檢查 { #check-it }

開啟互動式文件：[http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)。

你會看到類似這樣：

```console
$ pip install python-multipart
```

这是因为 **OAuth2** 使用“表单数据”来发送 `username` 和 `password`。

///

用下面的命令运行示例：

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

## 查看 { #check-it }

打开交互式文档：[http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)。

你会看到类似这样的界面：

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[66:73] hl[71] *}

### 執行應用 { #run-the-app }

你可以執行應用：

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

然後前往 `/docs` 的 UI，你會看到 FastAPI 使用這些模型來「文件化」API，也會用它們來「序列化」與「驗證」資料。
