Simple-WebSocket-Server

_This project has moved to https://gitlab.com/eidheim/Simple-WebSocket-Server._

Simple-WebSocket-Server

A very simple, fast, multithreaded, platform independent WebSocket (WS) and WebSocket Secure (WSS) server and client library implemented using C++11, Asio (both Boost.Asio and standalone Asio can be used) and OpenSSL. Created to be an easy way to make WebSocket endpoints in C++.

See https://gitlab.com/eidheim/Simple-Web-Server for an easy way to make REST resources available from C++ applications. Also, feel free to check out the new C++ IDE supporting C++11/14/17: https://gitlab.com/cppit/jucipp.

Features

• RFC 6455 mostly supported: text/binary frames, fragmented messages, ping-pong, connection close with status and reason.
• Asynchronous message handling
• Thread pool if needed
• Platform independent
• WebSocket Secure support
• Timeouts, if any of SocketServer::timeout_request and SocketServer::timeout_idle are >0 (default: SocketServer::timeout_request=5 seconds, and SocketServer::timeout_idle=0 seconds; no timeout on idle connections)
• Simple way to add WebSocket endpoints using regex for path, and anonymous functions
• An easy to use WebSocket and WebSocket Secure client library
• C++ bindings to the following OpenSSL methods: Base64, MD5, SHA1, SHA256 and SHA512 (found in crypto.hpp)

Usage

See ws_examples.cpp or wss_examples.cpp for example usage.

Dependencies

• Boost.Asio or standalone Asio
• OpenSSL libraries

Compile

Compile with a C++11 supported compiler:

mkdir build
cd build
cmake ..
make
cd ..

Run server and client examples

WS

./build/ws_examples

WSS

Before running the WSS-examples, an RSA private key (server.key) and an SSL certificate (server.crt) must be created. Follow, for instance, the instructions given here (for a self-signed certificate): http://www.akadia.com/services/ssh_test_certificate.html

Then:

./build/wss_examples
