다음 중 하나이며:

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

...흔히 사용되지 않는 것들도 있습니다:

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

HTTP 프로토콜에서는 이러한 "메소드"를 하나(또는 이상) 사용하여 각 경로와 통신할 수 있습니다.

API를 설계할 때 일반적으로 특정 행동을 수행하기 위해 특정 HTTP 메소드를 사용합니다.

일반적으로 다음과 같습니다:

* `POST`: 데이터를 생성하기 위해.
* `GET`: 데이터를 읽기 위해.
* `PUT`: 데이터를 수정하기 위해.
* `DELETE`: 데이터를 삭제하기 위해.

#### Operación

"Operación" aquí se refiere a uno de los "métodos" de HTTP.

Uno como:

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

...y los más exóticos:

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

En el protocolo de HTTP, te puedes comunicar con cada path usando uno (o más) de estos "métodos".

---

Un chemin, ou "path" est aussi souvent appelé route ou "endpoint".

///

#### Opération

"Opération" fait référence à une des "méthodes" HTTP.

Une de :

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

...ou une des plus exotiques :

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

Ao construir uma API, a "rota" é a principal forma de separar "preocupações" e "recursos".

#### Operação

"Operação" aqui se refere a um dos "métodos" HTTP.

Um dos:

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

...e os mais exóticos:

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

No protocolo HTTP, você pode se comunicar com cada rota usando um (ou mais) desses "métodos".
