Uygulamayı çalıştıralım:

<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)

    CIFSContext withGuestCrendentials();

    /**
     * Create a child context with specified credentials
     *
     * @param creds the credentials to use
     * @return a child context using using the given credentials
     */
    CIFSContext withCredentials(Credentials creds);

    /**

아래처럼 앱을 만든다면:

{* ../../docs_src/first_steps/tutorial002.py hl[3] *}

이를 `main.py` 파일에 넣고, `uvicorn`을 아래처럼 호출해야 합니다:

<div class="termy">

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

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

</div>

        return this.delegate.hasDefaultCredentials();
    }

    @Override
    public CIFSContext withCredentials(final Credentials creds) {
        return wrap(this.delegate.withCredentials(creds));
    }

    @Override
    public CIFSContext withDefaultCredentials() {
        return wrap(this.delegate.withDefaultCredentials());
    }

    @Override

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>.

Вы увидите следующую простенькую страницу:

        // Arrange: null reference to the interface
        SmbRenewableCredentials creds = null;

        // Act + Assert: invoking renew() on null triggers NullPointerException
        assertThrows(NullPointerException.class, () -> {
            // Intentional NPE through dereference of a null interface reference
            creds.renew();
        });
    }

    @Test

		Policies: []string{policy},

	if err != nil {

	}

	// Create an madmin client with user creds
	userAdmClient, err := madmin.NewWithOptions(s.endpoint, &madmin.Options{

	if err != nil {
