### Setting the `root_path` in the FastAPI app

Alternatively, if you don't have a way to provide a command line option like `--root-path` or equivalent, you can set the `root_path` parameter when creating your FastAPI app:

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

  private final PhantomReference<Object> frqReference;
  private final ReferenceQueue<Object> queue;

  // By preference, we will use the Thread constructor that has an `inheritThreadLocals` parameter.
  // But before Java 9, our only way not to inherit ThreadLocals is to zap them after the thread
  // is created, by accessing a private field.
  @CheckForNull

   * equal to any other equality groups added to this tester.
   *
   * <p>The {@code @Nullable} annotations on the {@code equalityGroup} parameter imply that the
   * objects, and the array itself, can be null. That is for programmer convenience, when the
   * objects come from factory methods that are themselves {@code @Nullable}. In reality neither the

     * and the transport will be in error.
     */

    protected abstract void doConnect() throws Exception;

    /* Tear down a connection. If the hard parameter is true, the diconnection
     * procedure should not initiate or wait for any outstanding requests on
     * this transport.
     */

    protected abstract void doDisconnect( boolean hard ) throws IOException;

}
```

### Configurando o `root_path` na aplicação FastAPI

Alternativamente, se você não tiver uma maneira de fornecer uma opção de linha de comando como `--root-path` ou equivalente, você pode definir o parâmetro `--root-path` ao criar sua aplicação FastAPI:

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

            return;
        }

        if (logger.isDebugEnabled()) {
            try {
                ManagementFactory.getRuntimeMXBean().getInputArguments().stream().forEach(s -> logger.debug("Parameter: {}", s));
                System.getProperties().entrySet().stream().forEach(e -> logger.debug("Property: {}={}", e.getKey(), e.getValue()));

Wenn sie diesen nicht empfängt, gibt sie den HTTP-Error 401 „Unauthorized“ zurück.

Und gibt einen Header `WWW-Authenticate` mit dem Wert `Basic` und einem optionalen `realm`-Parameter („Bereich“) zurück.
