"Operacje" tutaj odnoszą się do jednej z "metod" HTTP.

Jedna z:

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

...i te bardziej egzotyczne:

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

W protokole HTTP można komunikować się z każdą ścieżką za pomocą jednej (lub więcej) "metod".

Podczas tworzenia API zwykle używasz tych metod HTTP do wykonania określonej akcji.

Zazwyczaj używasz:

        // We might no longer need some connections
        connectionPool.scheduleCloser()
      }
    }
  }

  override fun handshake(): Handshake? = handshake

  /** Track a bad route in the route database. Other routes will be attempted first. */
  internal fun connectFailed(
    client: OkHttpClient,
    failedRoute: Route,
    failure: IOException,
  ) {

"Операция" это один из "методов" HTTP.

Таких, как:

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

...и более экзотических:

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

По протоколу HTTP можно обращаться к каждому пути, используя один (или несколько) из этих "методов".

При создании API принято использовать конкретные HTTP-методы для выполнения определенных действий.
