コードから直接Uvicornサーバーを実行しているため、デバッガーから直接Pythonプログラム (FastAPIアプリケーション) を呼び出せます。

---

例えば、Visual Studio Codeでは、次のことが可能です:

* 「デバッグ」パネルに移動。
* 「構成の追加...」
* 「Python」を選択。
* オプション「`Python: Current File (Integrated Terminal)`」を指定してデバッガーを実行。

すると、**FastAPI** コードでサーバーが起動され、ブレークポイントで停止したりするでしょう。

以下の様な画面になります:

Pycharmを使用する場合、次のことが可能です:

* 「実行」メニューをオープン。

 *
 * Note that an allocation may be released before its stream is completed. This is intended to make
 * bookkeeping easier for the caller: releasing the allocation as soon as the terminal stream has
 * been found. But only complete the stream once its data stream has been exhausted.

interface Connection {
  /** Returns the route used by this connection. */
  fun route(): Route

  /**

Once successfully set restart the MinIO instance.

```
mc admin service restart myminio
```

### Using WebIdentiy API

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

**Note**: Make sure you put `"fastapi[standard]"` in quotes to ensure it works in all terminals.

## Example { #example }

### Create it { #create-it }

Create a file `main.py` with:

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")

            runningProcessMap.put(sessionId, jobProcess);
            return jobProcess;
        } catch (final IOException e) {
            throw new JobProcessingException("Crawler Process terminated.", e);
        }
    }

    /**
     * Destroys the process associated with the given session ID.
     *
     * @param sessionId unique identifier for the process session

			if cr.debug {
				fmt.Println("trailer returned:", err)
			}
			if err != nil {
				cr.err = err
				return 0, err
			}
		}
		cr.err = io.EOF
		return n, cr.err
	}
	// read final terminator.
	err = mustRead('\r', '\n')
	if err != nil && err != io.EOF {
		cr.err = err
		return n, cr.err
	}

	cr.offset = copy(buf, cr.buffer)
	n += cr.offset
	return n, err
}

            processHelper.startProcess(sessionId, cmdList, pbCall);
            fail("Expected JobProcessingException");
        } catch (JobProcessingException e) {
            assertTrue(e.getMessage().contains("Crawler Process terminated"));
        }
    }

    @Test
    public void test_startProcess_replaceExistingProcess() {
        String sessionId = "test_replace";

Você pode definir tarefas em segundo plano para serem executadas *após* retornar uma resposta.

Isso é útil para operações que precisam acontecer após uma request, mas que o cliente não precisa realmente esperar a operação terminar antes de receber a resposta.

Isso inclui, por exemplo:

* Notificações por e-mail enviadas após realizar uma ação:

Wenn Sie FastAPI installieren (z. B. mit `pip install "fastapi[standard]"`), erhalten Sie ein Kommandozeilenprogramm, das Sie im Terminal ausführen können.

Um Ihre FastAPI-App für die Entwicklung auszuführen, können Sie den Befehl `fastapi dev` verwenden:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev

When you install FastAPI (e.g. with `pip install "fastapi[standard]"`), it comes with a command line program you can run in the terminal.

To run your FastAPI app for development, you can use the `fastapi dev` command:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev
