    ## Example

    ```python
    from fastapi import Depends, FastAPI
    from fastapi.security import APIKeyCookie

    app = FastAPI()

    cookie_scheme = APIKeyCookie(name="session")


    @app.get("/items/")
    async def read_items(session: str = Depends(cookie_scheme)):
        return {"session": session}
    ```
