So, all these are different origins:

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`

Even if they are all in `localhost`, they use different protocols or ports, so, they are different "origins".

It can't handle nested models very well. So, if the JSON body in the request is a JSON object that has inner fields that in turn are nested JSON objects, it cannot be properly documented and validated.

* Cả hai _đường dẫn_ sử dụng toán tử `GET` (cũng đươc biết đến là _phương thức_ HTTP).
* _Đường dẫn_ `/items/{item_id}` có một _tham số đường dẫn_ `item_id`, nó là một tham số kiểu `int`.
* _Đường dẫn_ `/items/{item_id}`  có một _tham số query string_ `q`, nó là một tham số tùy chọn kiểu `str`.

* There's a subdirectory `app/routers/` with another file `__init__.py`, so it's a "Python subpackage": `app.routers`.
* The file `app/routers/items.py` is inside a package, `app/routers/`, so, it's a submodule: `app.routers.items`.
* The same with `app/routers/users.py`, it's another submodule: `app.routers.users`.
* There's also a subdirectory `app/internal/` with another file `__init__.py`, so it's another "Python subpackage": `app.internal`.

When you want to call an `async def` function, you have to "await" it. So, this won't work:

```Python
# This won't work, because get_burgers was defined with: async def
burgers = get_burgers(2)
```
