### 확인하기

That way, you can edit the documentation/source files and see the changes live.

/// tip

Alternatively, you can perform the same steps that scripts does manually.

Go into the language directory, for the main docs in English it's at `docs/en/`:

```console
$ cd docs/en/
```

Then run `mkdocs` in that directory:

```console
$ mkdocs serve --dev-addr 8008
```

## メッセージの送受信

WebSocketルートでは、 `await` を使ってメッセージの送受信ができます。

```Python hl_lines="48-52"
{!../../docs_src/websockets/tutorial001.py!}
```

バイナリやテキストデータ、JSONデータを送受信できます。

## 試してみる

ファイル名が `main.py` である場合、以下の方法でアプリケーションを実行します。

<div class="termy">

```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)
```

It could look like this:

```JSON  hl_lines="7"
{
  "name": "frontend-app",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "generate-client": "openapi-ts --input http://localhost:8000/openapi.json --output ./src/client --client axios"
  },
  "author": "",
  "license": "",
  "devDependencies": {

      client2.newCall(request).execute().use { response ->
        println("Response 2 succeeded: $response")
      }
    } catch (e: IOException) {
      println("Response 2 failed: $e")
    }
  }
}

fun main() {
  PerCallSettings().run()

      }

      println(fileSystem.source(path).buffer().readUtf8())
    }
  }

  companion object {
    val MEDIA_TYPE_JSON = "application/json".toMediaType()
  }
}

fun main() {
  PostPath().run()

          .build();
      Request newRequest = request.newBuilder()
          .headers(newHeaders)
          .build();
      return chain.proceed(newRequest);
    }
  }

  public static void main(String... args) throws Exception {
    new CurrentDateHeader().run();
  }

      if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);

      System.out.println(response.body().string());
    }
  }

  public static void main(String... args) throws Exception {
    new PostString().run();
  }

<div class="termy">

```console
$ cd ~/code/prisoner-of-azkaban

$ python main.py

// Erro ao importar o Sirius, ele não está instalado 😱

Vediamo il comando `uvicorn main:app` in dettaglio:

* `main`: il file `main.py` (il "modulo" Python).
* `app`: l'oggetto creato dentro `main.py` con la riga di codice `app = FastAPI()`.
* `--reload`: ricarica il server se vengono rilevati cambiamenti del codice. Usalo solo durante la fase di sviluppo.
