## Recap { #recap }

Apart from all the fancy words used here, the **Dependency Injection** system is quite simple.

Just functions that look the same as the *path operation functions*.

Check how deprecated and non-deprecated *path operations* look like:

        resp.decode(packet, 0);
        assertEquals(Smb2IoctlRequest.FSCTL_SRV_COPYCHUNK, resp.getCtlCode());

        assertNotNull(resp.getFileId());
        assertEquals(16, resp.getFileId().length);
        assertEquals(12, resp.getOutputLength());

This is not a limitation of **FastAPI**, it's part of the HTTP protocol.
