## Connect with the author { #connect-with-the-author }

You can connect with [me (Sebastián Ramírez / `tiangolo`)](https://tiangolo.com), the author.

You can:

* [Follow me on **GitHub**](https://github.com/tiangolo).
    * See other Open Source projects I have created that could help you.
    * Follow me to see when I create a new Open Source project.

If you don't select any scope, you will be "authenticated", but when you try to access `/users/me/` or `/users/me/items/` you will get an error saying that you don't have enough permissions. You will still be able to access `/status/`.

And if you select the scope `me` but not the scope `items`, you will be able to access `/users/me/` but not `/users/me/items/`.

    return form_data


@app.get("/users/me")
def read_users_me(current_user: User | None = Depends(get_current_user)):
    if current_user is None:
        return {"msg": "Create an account first"}
    return current_user


client = TestClient(app)


def test_security_oauth2():
    response = client.get("/users/me", headers={"Authorization": "Bearer footokenbar"})

    return form_data


@app.get("/users/me")
# Here we use string annotations to test them
def read_current_user(current_user: "User" = Depends(get_current_user)):
    return current_user


client = TestClient(app)


def test_security_oauth2():
    response = client.get("/users/me", headers={"Authorization": "Bearer footokenbar"})
    assert response.status_code == 200, response.text

API ドキュメントを開くと、認証して、許可するスコープを指定できます。

<img src="/img/tutorial/security/image11.png">

どのスコープも選択しない場合は「認証済み」にはなりますが、`/users/me/` や `/users/me/items/` にアクセスしようとすると、権限が不足しているというエラーになります。`/status/` には引き続きアクセスできます。

`me` スコープだけを選択し、`items` スコープを選択しない場合は、`/users/me/` にはアクセスできますが、`/users/me/items/` にはアクセスできません。

これは、ユーザーがアプリケーションに与えた権限の範囲に応じて、サードパーティアプリケーションがこれらの path operation のいずれかに、ユーザーから提供されたトークンでアクセスしようとしたときに起こる動作です。
