 # Общая документация мессенджера Influence

-## Структура мессенджера

-Связь между узлами - точка-точка

-GUI - API ==== API - GUI

-GUI - примитивная программа под Linux/Windows/Android, которая умеет отображать сообщения и вызывать функции ядра (API).
-API - ядро мессенджера. Достаточно подключить *main.hpp*, чтобы вызывать функции ядра. Такая структура позволяет писать какие угодно клиенты.

 ## Протокол обмена

 Обмен сообщениями ведётся по UDP протоколу в формате JSON.
-При любой успешной отправке данных обновляем поле last_connect у контакта.
-Если пришло сообщение от контакта, которого нет в адресной книге - то оно отбрасывается.

 В ответ приходит массив с `true` или `false`. Если `true` - сообщение успешно отправлено, `false` - сообщение недоставлено.

 Если человек, которому мы отправляем сообщение offline - то, во-первых, оно сохраняется у себя на сервере, для последующей отправки.
 Во-вторых, можно попросить какого-то друга его переотправить. Для этого выбираем случайно несколько друзей из списка контактов, у которых `can_resend == 1` и отправляем им запрос.
