你可以接收與傳送二進位、文字與 JSON 資料。

## 試試看 { #try-it }

如果你的檔案名為 `main.py`，用以下指令執行應用：

<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>

在瀏覽器開啟 [http://127.0.0.1:8000](http://127.0.0.1:8000)。

你會看到一個像這樣的簡單頁面：

您可以接收和发送二进制、文本和 JSON 数据。

## 尝试一下 { #try-it }

将代码放在 `main.py`，然后运行你的应用程序：

<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>

在浏览器中打开 [http://127.0.0.1:8000](http://127.0.0.1:8000)。

您将看到一个简单的页面，如下所示：

<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)
```

</div>

### Weiterleitungen mit HTTPS { #redirects-with-https }

Angenommen, Sie definieren eine *Pfadoperation* `/items/`:

<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)
```

</div>

### Редиректы с HTTPS { #redirects-with-https }

Например, вы объявили операцию пути `/items/`:

<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)
```

</div>

### Перенаправлення з HTTPS { #redirects-with-https }

Наприклад, припустимо, ви визначили *операцію шляху* `/items/`:

none;\n}\n\n.card.bg-green .bootstrap-datetimepicker-widget table thead tr:first-child th:hover,\n.card.bg-green .bootstrap-datetimepicker-widget table td.day:hover,\n.card.bg-green .bootstrap-datetimepicker-widget table td.hour:hover,\n.card.bg-green .bootstrap-datetimepicker-widget table td.minute:hover,\n.card.bg-green .bootstrap-datetimepicker-widget table td.second:hover,\n.card.bg-gradient-green .bootstrap-datetimepicker-widget table thead tr:first-child th:hover,\n.card.bg-gradient-green .bootstrap...

```

Sonrasında, environment variable `OPENAPI_URL`'i boş string olarak ayarlayarak OpenAPI'yi (UI docs dahil) devre dışı bırakabilirsiniz; örneğin:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

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

</div>

Böylece `/openapi.json`, `/docs` veya `/redoc` URL'lerine giderseniz, aşağıdaki gibi bir `404 Not Found` hatası alırsınız:

### Перевірте автоматичну документацію API { #check-the-automatic-api-docs }

Тепер запустіть команду `fastapi`:

<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>

І відкрийте документацію за адресою [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

Then you could disable OpenAPI (including the UI docs) by setting the environment variable `OPENAPI_URL` to the empty string, like:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

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

</div>

Then if you go to the URLs at `/openapi.json`, `/docs`, or `/redoc` you will just get a `404 Not Found` error like:
