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

{* ../../docs_src/bigger_applications/app_an_py39/dependencies.py hl[3,6:8] title["app/dependencies.py"] *}

/// tip | Tipp

Um dieses Beispiel zu vereinfachen, verwenden wir einen erfundenen Header.

        // DACL at offset 20
        securityDescriptorBytes[16] = 20;
        securityDescriptorBytes[17] = 0;
        securityDescriptorBytes[18] = 0;
        securityDescriptorBytes[19] = 0;

        // DACL header at offset 20
        securityDescriptorBytes[20] = 2; // ACL revision
        securityDescriptorBytes[21] = 0; // sbz1
        securityDescriptorBytes[22] = 8; // ACL size (low byte)

            assertEquals(error, echoResponse.getException());
        }
    }

## TensorFlow's Official CI and Build/Test Scripts

TensorFlow's official CI jobs run the scripts in this folder. Our internal CI
system, Kokoro, schedules our CI jobs by combining a build script with a file
from the `envs` directory that is filled with configuration options:

-   Nightly jobs (Run nightly on the `nightly` branch)
