For large responses, returning a `Response` directly is much faster than returning a dictionary.

    !!! tip
        Prefer to use the `Annotated` version if possible.

    ```Python hl_lines="19-22  26-27"
    {!> ../../../docs_src/security/tutorial002.py!}
    ```

## Inject the current user

So now we can use the same `Depends` with our `get_current_user` in the *path operation*:

=== "Python 3.10+"

    ```Python hl_lines="31"

If you pass a custom list of `servers` and there's a `root_path` (because your API lives behind a proxy), **FastAPI** will insert a "server" with this `root_path` at the beginning of the list.

For example:

```Python hl_lines="4-7"
{!../../../docs_src/behind_a_proxy/tutorial003.py!}
```

Will generate an OpenAPI schema like:

@needs_py310
@needs_pydanticv2
def test_openapi_schema(client: TestClient):
    response = client.get("/openapi.json")
    assert response.status_code == 200, response.text
    # insert_assert(response.json())
    assert response.json() == {
        "openapi": "3.1.0",
        "info": {"title": "FastAPI", "version": "0.1.0"},
        "paths": {
            "/items/{item_id}": {
                "put": {

    # Just for coverage
    new_subscription(body={}, token="Bearer 123")


def test_openapi_schema():
    response = client.get("/openapi.json")
    assert response.status_code == 200, response.text
    # insert_assert(response.json())
    assert response.json() == {
        "openapi": "3.1.0",
        "info": {"title": "FastAPI", "version": "0.1.0"},
        "paths": {},
        "webhooks": {
            "new-subscription": {

Das System (in diesem Fall **FastAPI**) kümmert sich dann darum, Ihren Code mit den erforderlichen Abhängigkeiten zu versorgen („die Abhängigkeiten einfügen“ – „inject the dependencies“).

Das ist sehr nützlich, wenn Sie:

* Eine gemeinsame Logik haben (die gleiche Code-Logik immer und immer wieder).
* Datenbankverbindungen teilen.
