Здравствуйте, это моя четвёртая статья на хабре, на этот раз я выйду за область ML решений и познакомлю вас с другим своим проектом.

В процессе работы над различными проектами, рано или поздно возникает необходимость реализации клиент/серверных протоколов передачи данных, это может быть один из стандартных протоколов типа HTTP, так и реализация своих собственных. Реализация как клиента, так и сервера, всегда занимает большое количество времени, не говоря уже об отладке и вся работа сводится к поиску готовых решений, таких как CURL или NGINX. Когда же требуется реализовать работу своего собственного протокола передачи данных, начинаются проблемы. В один из таких моментов мне пришла в голову идея реализации конструктора, который служил бы каркасом основного приложения и всю работу с сетью брал на себя, чтобы оставалось реализовать только сам протокол. Для этих целей мною был разработан проект AWH.

На данный момент на AWH в качестве демонстрации работоспособности, реализованы следующие примеры:

DNS резолвер
HTTP(S) клиент
WEB сервер
Socks5 прокси-сервер
HTTPS прокси-сервер
WebSocket клиент
WebSocket сервер

Поддержка алгоритмов сжатия:

Поддержка методов авторизации:

Поддержка операционных систем:

Windows (TCP, TLS, UDP, DTLS)
Linux (TCP, TLS, UDP, DTLS, SCTP, UnixSocket)
FreeBSD (TCP, TLS, UDP, DTLS, SCTP, UnixSocket)
MacOS X (TCP, TLS, UDP, DTLS, UnixSocket)

Установка и сборка:

Для сборки AWH необходимо сначала собрать внешние зависимости. Сам проект базируется на LibEv для *.Nix подобных операционных систем и на LibEvent2 для Windows.

FreeBSD

Windows

Для сборки AWH под операционную систему Windows необходимо сначала настроить среду разработки

Для начала нужно установить следующие приложения:

Далее продолжаем работу в терминале MSYS2 MinGW64

# Устанавливаем все необходимые нам зависимости
$ pacman -Syuu
$ pacman -S mingw64/mingw-w64-x86_64-cmake
$ pacman -S make
$ pacman -S curl
$ pacman -S wget
$ pacman -S mc
$ pacman -S gdb

$ pacman -S clang
$ pacman -S git
$ pacman -S --needed base-devel mingw-w64-x86_64-toolchain
$ pacman -S mingw-w64-x86_64-dlfcn

# Клонирование проекта

Как видно из примеров, шаблоны различных серверов однотипны и максимально упрощены, что позволяет использовать как каркас любого проекта. Клиенты и сервера можно комбинировать как и различные типы сокетов и протоколов, например можно запустить прокси-сервер через unix-сокет или WebSocket-сервер как DTLS.

Я не привожу сравнение производительности с другими проектами такими, как CURL или NGINX, так-как не претендую на уникальность. Примеры сервисов приведены только, для демонстрации работы конструктора, все протоколы реализованы самостоятельно.
