## Проверка в действии { #try-it }

Если ваш файл называется `main.py`, то запустите приложение 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>

Откройте браузер по адресу <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a>.

<div class="termy">

```console
$ fastapi run --forwarded-allow-ips="*"

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

您可以接收和发送二进制、文本和 JSON 数据。

## 尝试一下

如果您的文件名为 `main.py`，请使用以下命令运行应用程序：

```console
$ uvicorn main:app --reload

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

在浏览器中打开 <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a>。

您将看到一个简单的页面，如下所示：

        ```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
        ```
        »»»

    Result (German):

        «««
        ```console

        b'<h1><a href="http://testserver/items/foo">Item ID: foo</a></h1>'
        in response.content
    )
    response = client.get("/static/styles.css")
    assert response.status_code == 200, response.text
    assert b"color: green;" in response.content
    shutil.rmtree("./templates")

                        context, installationToolchains, "The specified installation toolchains file does not exist"));
        options.color().ifPresent(color -> {
            String c = color.toLowerCase(Locale.ENGLISH);
            if (!Arrays.asList("always", "yes", "force", "never", "no", "none", "auto", "tty", "if-tty")
                    .contains(c)) {

Если ваш сервер находится за доверенным прокси и только прокси обращается к нему, этого достаточно, чтобы он принимал IP этого прокси.

<div class="termy">

```console
$ fastapi run --forwarded-allow-ips="*"

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