<div class="termy">

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

### アプリの起動 { #run-the-app }

アプリを起動します:

<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>

その後 `/docs` の UI にアクセスすると、FastAPI がこれらのモデルを使って API をドキュメント化し、同時にデータのシリアライズとバリデーションにも使っていることがわかります。

```bash
# 向宇宙打印问候
echo "Hello universe"
```

...以及一个控制台代码示例...

```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 server
        Searching for package file structure
```

...以及另一个控制台代码示例...

```console
// 创建目录 "code"
$ mkdir code
// 切换到该目录
$ cd code
```

echo "Hello universe"
```

...y un ejemplo de código de consola...

```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 server
        Searching for package file structure
```

...y otro ejemplo de código de consola...

```console
// Crea un directorio "Code"
$ mkdir code

echo "Hello universe"
```

... et un exemple de code console ...

```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 server
        Searching for package file structure
```

... et un autre exemple de code console ...

```console
// Créer un répertoire "Code"
$ mkdir code

      return null;
    } else {
      Range<K> range = ranges.get(index);
      return range.contains(key) ? immutableEntry(range, values.get(index)) : null;
    }
  }

  @Override
  public Range<K> span() {
    if (ranges.isEmpty()) {
      throw new NoSuchElementException();
    }
    Range<K> firstRange = ranges.get(0);
    Range<K> lastRange = ranges.get(ranges.size() - 1);

```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：
