“请求已成功,请求所希望的响应头或数据体将随此响应返回。“ — wikipedia

GET an entity corresponding to the requested resource is sent in the response;

HEAD the entity-header fields corresponding to the requested resource are sent in the response without any message-body;

POST an entity describing or containing the result of the action;“ — ietf
