Also fügen wir sie in ihr eigenes `dependencies`-Modul (`app/dependencies.py`) ein.

Wir werden nun eine einfache Abhängigkeit verwenden, um einen benutzerdefinierten `X-Token`-Header zu lesen:

//// tab | Python 3.9+

```Python hl_lines="3  6-8" title="app/dependencies.py"
{!> ../../docs_src/bigger_applications/app_an_py39/dependencies.py!}
```

////

Мы поместим их в отдельный модуль `dependencies` (`app/dependencies.py`).

Теперь мы воспользуемся простой зависимостью, чтобы прочитать кастомизированный `X-Token` из заголовка:

//// tab | Python 3.9+

```Python hl_lines="3  6-8" title="app/dependencies.py"
{!> ../../docs_src/bigger_applications/app_an_py39/dependencies.py!}

    val response1 = responses.take()
    assertThat(response1).isEqualTo("")
    assertThat(server.takeRequest().exchangeIndex).isEqualTo(0)

    // Now make the second request which will restrict the first HTTP/2 connection from creating new
    // streams.
    client.newCall(request).enqueue(callback)
    val response2 = responses.take()
    assertThat(response2).isEqualTo("DEF")

                    sha1ChecksumObserver = addChecksumObserver(wagon, "SHA-1");

                    // reset the retry flag.
                    retry = false;

                    // This should take care of creating destination directory now on
                    if (destination.exists() && !force) {
                        try {

- On finding at least one associated policy, MinIO generates temporary credentials for the user storing the list of groups in a cryptographically secure session token. The temporary access key, secret key and session token are returned to the user.
- The user can now use these credentials to make requests to the MinIO server.

이제 **FastAPI** 앱이 있는 `main.py` 파일에 몇 가지 다른 **경로 작업** 이 추가된 경우를 생각해봅시다.

단일 오류를 반환할 수 있는 `GET` 작업이 있습니다.

여러 다른 오류를 반환할 수 있는 `POST` 작업이 있습니다.

두 *경로 작업* 모두 `X-Token` 헤더를 요구합니다.

    serverSocket = ServerSocket()

### 3. Example

- Upon receiving a LIST request with an expired continue token, the apiserver now returns a continue token together with the 410 "the from parameter is too old" error. If the client does not care about getting a list from a consistent snapshot, the client can use this token to continue listing from the next key, but the returned chunk will be from the latest snapshot.
