For that you need to access the request directly.

{* ../../docs_src/using_request_directly/tutorial001.py hl[1,7:8] *}

By declaring a *path operation function* parameter with the type being the `Request` **FastAPI** will know to pass the `Request` in that parameter.

/// tip

Note that in this case, we are declaring a path parameter beside the request parameter.

Python has support for optional "type hints" (also called "type annotations").

These **"type hints"** or annotations are a special syntax that allow declaring the <abbr title="for example: str, int, float, bool">type</abbr> of a variable.

By declaring types for your variables, editors and tools can give you better support.

## OAuth2 Security scheme { #oauth2-security-scheme }

The first change is that now we are declaring the OAuth2 security scheme with two available scopes, `me` and `items`.

The `scopes` parameter receives a `dict` with each scope as a key and the description as the value:

{* ../../docs_src/security/tutorial005_an_py310.py hl[63:66] *}

Because we are now declaring those scopes, they will show up in the API docs when you log-in/authorize.

    }

    // Helper: reflectively set private/protected field on an object
    private static void setField(Object target, Class<?> declaring, String name, Object value) {
        try {
            Field f = declaring.getDeclaredField(name);
            f.setAccessible(true);
            f.set(target, value);
        } catch (Exception e) {
            throw new RuntimeException(e);

     * @param args the array of objects to be passed as arguments to the constructor invocation
     * @return a new object created by invoking the constructor
     * @throws InstantiationRuntimeException if the class declaring the constructor is abstract
     * @throws IllegalAccessRuntimeException if the number of actual and formal parameters differ, if primitive arguments cannot be converted, or if the class is related to enums

In some cases you don't really need the return value of a dependency inside your *path operation function*.

Or the dependency doesn't return a value.

But you still need it to be executed/solved.

For those cases, instead of declaring a *path operation function* parameter with `Depends`, you can add a `list` of `dependencies` to the *path operation decorator*.

## Use the dependency { #use-the-dependency }

Then we can use the dependency with:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[23] *}

/// info

Notice that we are only declaring one dependency in the *path operation function*, the `query_or_cookie_extractor`.

But **FastAPI** will know that it has to solve `query_extractor` first, to pass the results of that to `query_or_cookie_extractor` while calling it.

Also, before that, in previous versions, the `request` object was passed as part of the key-value pairs in the context for Jinja2.

///

/// tip

By declaring `response_class=HTMLResponse` the docs UI will be able to know that the response will be HTML.

///

/// note | Technical Details

You could also use `from starlette.templating import Jinja2Templates`.

Changing the default { #changing-the-default }

Later, in the [Advanced User Guide](../advanced/response-change-status-code.md){.internal-link target=_blank}, you will see how to return a different status code than the default you are declaring here....
