A very simple, fast, multithreaded, platform independent HTTP and HTTPS server and client library implemented using C++11 and Boost.Asio. Created to be an easy way to make REST resources available from C++ applications.
See also https://github.com/eidheim/Simple-WebSocket-Server for an easy way to make WebSocket/WebSocket Secure endpoints in C++.
- Thread pool
- Platform independent
- HTTPS support
- HTTP persistent connection (for HTTP/1.1)
- Client supports chunked transfer encoding
- Timeouts, if any of Server::timeout_request and Server::timeout_content are >0 (default: Server::timeout_request=5 seconds, and Server::timeout_content=300 seconds)
- Simple way to add REST resources using regex for path, and anonymous functions
- Possibility to flush response to clients both synchronously (Server::flush) and asynchronously (Server::async_flush).
###Usage
Note: newest version is NOT backward compatible with earlier versions.
See http_examples.cpp or https_examples.cpp for example usage.
See particularly the JSON-POST (using Boost.PropertyTree) and the GET /match/[number] examples, which are most relevant.
The default_resource includes example use of Server::flush. Note that Server::async_flush might be slightly slower than Server::flush unless you need to process computationally expensive tasks while simultaneously sending large datasets to a client.
Boost C++ libraries must be installed, go to http://www.boost.org for download and instructions.
For HTTPS: OpenSSL libraries from https://www.openssl.org are required.
Compile with a C++11 compiler supporting regex (for instance g++ 4.9):
On Linux using g++: add -pthread
Note: added -lboost_thread to make the json-example thread safe. Also added -lboost_coroutine -lboost_context to make synchronous and asynchronous flushing of response stream work. On some systems you might have to use postfix -mt to link to these libraries.
You can now also compile using CMake and make:
cmake .
make
g++ -O3 -std=c++11 http_examples.cpp -lboost_system -lboost_thread -lboost_coroutine -lboost_context -o http_examples
Then to run the server and client examples: ./http_examples
Also, direct your favorite browser to for instance http://localhost:8080/
g++ -O3 -std=c++11 https_examples.cpp -lboost_system -lboost_thread -lboost_coroutine -lboost_context -lssl -lcrypto -o https_examples
Before running the server, 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 to run the server and client examples: ./https_examples
Also, direct your favorite browser to for instance https://localhost:8080/
