Simple-HTTP-2-Web-Server

This is a simple HTTP2.0(h2c) web server library for Linux. This library uses only the c++ standard template library and some C functions.

Included features:

• HTTP1.1 to HTTP2 upgrade.
• HTTP2 Settings sent and received by clients and server upon connection.
• Sending HTML files.
• Decoding of HTTP2 frames.
• Management of HTTP2 streams.
• Error handling of streams and connections.
• Partial header decoding.

Useful methods:

• ServerLib(int port); - Create a server object with specified port number.
• int startServer(); - Binds the socket and starts the server.
• int webBind(std::string webDir, std::string diskDir); - Binds a path on the web server to a directory on the disk.
• int webUnbind(std::string webDir); - Unbinds a path on the web server

Current limitations:

• No support for TLS yet.
• No support for UDP communication.
• Huffman encoding is incomplete.
• Binding of a function to a web path.

Example:

The file webserver.cpp is an example of how to use this libary.

Testing:

Test the server with nghttp or similar programs. There is a shellscript (./serverTesting/get.sh) to run a HTTP2 get request to the server. You can test the HTTP1.1 portion of the server with curl or a web browser.
