How to create a Ruby gem that adds Rake tasks

How to create a Ruby gem that adds Rake tasks

Create a gem

One way to do this is to use bundler to scaffold our gem:

bundler gem my_gem

Add rake tasks to our gem

I prefer to put tasks meant to manage the gem itself in lib/tasks, and tasks the gem is meant to provide to gem users in lib/my_gem/tasks.

Про токены, JSON Web Tokens (JWT), аутентификацию и авторизацию. Token-Based Authentication

Про токены, JSON Web Tokens (JWT), аутентификацию и авторизацию. Token-Based Authentication

Preconditions:

В данной заметке рассматривается работа JWT с симметичным алгоритмом шифрования (HS256/HS384/HS512)

Основы:

Аутентификация(authentication, от греч. αὐθεντικός [authentikos] – реальный, подлинный; от αὐθέντης [authentes] – автор) - это процесс проверки учётных данных пользователя (логин/пароль). Проверка подлинности пользователя путём сравнения введённого им логина/пароля с логином/паролем, сохранённым в базе данных пользователей.

Авторизация(authorization — разрешение, уполномочивание) - это проверка прав пользователя на доступ к определенным ресурсам.
