REST

Модуль

Приклад реалізації REST API:

-module(users). -behaviour(rest). -compile({parse_transform, rest}). -include("users.hrl"). -export([init/0, populate/1, exists/1, get/0, get/1, post/1, delete/1]). -rest_record(user). init() -> ets:new(users, [public, named_table, {keypos, #user.id}]). populate(Users) -> ets:insert(users, Users). exists(Id) -> ets:member(users, wf:to_list(Id)). get() -> ets:tab2list(users). get(Id) -> [User] = ets:lookup(users, wf:to_list(Id)), User. delete(Id) -> ets:delete(users, wf:to_list(Id)). post(#user{} = User) -> ets:insert(users, User); post(Data) -> post(from_json(Data, #user{})).

Використання API

$ curl -i -X POST -d "id=vlad" localhost:8005/rest/users $ curl -i -X POST -d "id=doxtop" localhost:8005/rest/users $ curl -i -X GET localhost:8005/rest/users $ curl -i -X PUT -d "id=5HT" localhost:8005/rest/users/vlad $ curl -i -X GET localhost:8005/rest/users/5HT $ curl -i -X DELETE localhost:8005/rest/users/5HT
