#### Toán tử (Operation)

"Toán tử" ở đây được nhắc tới là một trong các "phương thức" HTTP.

Một trong những:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...và một trong những cái còn lại:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

Trong giao thức HTTP, bạn có thể giao tiếp trong mỗi đường dẫn sử dụng một (hoặc nhiều) trong các "phương thức này".
