### 运行应用程序

您可以运行这个应用程序：

<div class="termy">

```console
$ fastapi dev main.py

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

</div>

然后在 `/docs` UI 中，您能够看到 **FastAPI** 会用这些**模型**来**记录** API，并且还会用它们来**序列化**和**验证**数据。

<div class="screenshot">

echo "Hello universe"
```

...и пример вывода в консоли...

```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
```

...и ещё один пример вывода в консоли...

```console
// Создать директорию "Code"
$ mkdir code

echo "Hello universe"
```

... und ein Konsolen-Codebeispiel ...

```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
```

... und noch ein Konsolen-Codebeispiel ...

```console
// Ein Verzeichnis „Code“ erstellen
$ mkdir code

<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)
```

</div>

### 애플리케이션 실행하기

애플리케이션을 실행하려면 다음 명령을 사용합니다:

<div class="termy">

```console
$ fastapi dev main.py

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

</div>

    assertEquals(expected, view);
    assertEquals(expected.asRanges(), view.asRanges());
    assertEquals(expected.isEmpty(), view.isEmpty());

    if (!expected.isEmpty()) {
      assertEquals(expected.span(), view.span());
    }

    for (int i = MIN_BOUND - 1; i <= MAX_BOUND + 1; i++) {
      assertEquals(expected.contains(i), view.contains(i));
      assertEquals(expected.rangeContaining(i), view.rangeContaining(i));
    }

Это связано с тем, что **OAuth2** использует «данные формы» для отправки `username` и `password`.

Запустите пример командой:

<div class="termy">

```console
$ fastapi dev main.py

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

</div>

## Проверка { #check-it }

					</la:link>
					<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbar" aria-controls="navbar"
						aria-expanded="false" aria-label="Toggle navigation">
						<span class="navbar-toggler-icon"></span>
					</button>
					<div class="collapse navbar-collapse" id="navbar">
						<div class="me-auto"></div>
						<ul class="nav navbar-nav">
							<c:if test="${eoled}">

<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)
```

</div>

/// tip | Tipp

```

Isso ocorre porque o **OAuth2** usa "form data" para enviar o `username` e o `password`.

///

Execute o exemplo com:

<div class="termy">

```console
$ fastapi dev main.py

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

</div>
