That doesn't add any extra security to your API, the *path operations* will still be available where they are.

If there's a security flaw in your code, it will still exist.

For example, you could identify a "car" or a "blog post".

Then you could add permissions about that entity, like "drive" (for the car) or "edit" (for the blog).

And then, you could give that JWT token to a user (or bot), and they could use it to perform those actions (drive the car, or edit the blog post) without even needing to have an account, just with the JWT token your API generated for that.

I'll tell you a bit more about these **concepts** here, and that would hopefully give you the **intuition** you would need to decide how to deploy your API in very different environments, possibly even in **future** ones that don't exist yet.

By considering these concepts, you will be able to **evaluate and design** the best way to deploy **your own APIs**.

In the next chapters, I'll give you more **concrete recipes** to deploy FastAPI applications.

* find the module `dependencies` (an imaginary file at `app/routers/dependencies.py`)...
* and from it, import the function `get_token_header`.

But that file doesn't exist, our dependencies are in a file at `app/dependencies.py`.

Remember how our app/file structure looks like:

<img src="/img/tutorial/bigger-applications/package.svg">

The two dots `..`, like in:

* <abbr title="Puts them together, as one. With the contents of one after the other.">Concatenates</abbr> them with a space in the middle.

```

### Edit it

It's a very simple program.

But now imagine that you were writing it from scratch.

At some point you would have started the definition of the function, you had the parameters ready...

            background_tasks=background_tasks,
            response=response,
            dependency_overrides_provider=dependency_overrides_provider,
            dependency_cache=dependency_cache,
            async_exit_stack=async_exit_stack,
        )
        (
            sub_values,
            sub_errors,
            background_tasks,
            _,  # the subdependency returns the same response we have

# Зависимости с yield

FastAPI поддерживает зависимости, которые выполняют некоторые <abbr title='также известные как "exit", "cleanup", "teardown", "close", "context managers", ...'>дополнительные действия после завершения работы</abbr>.

Для этого используйте `yield` вместо `return`, а дополнительный код напишите после него.

!!! tip "Подсказка"
    Обязательно используйте `yield` один-единственный раз.
