st_asio_wrapper

Overview

st_asio_wrapper is an asynchronous c/s framework based on Boost.Asio, besides all benefits brought by Boost and Boost.Asio, it also contains:

1. Based on message just like UDP with several couple of build-in packer and unpacker;
2. Support packer and unpacker customization, and replacing packer and unpacker at run-time;
3. Automatically reconnect to the server after link broken;
4. Support object pool, object reusing and restoration;
5. Worker thread management;
6. Support message buffer;
7. Widely support timers;
8. Support TCP/UDP and Unix domin TCP/UDP;
9. Support reliable UDP (base on KCP -- https://github.com/skywind3000/kcp);
10. Support ssl;

Quick start:

server:

Derive your own socket from server_socket_base, you must at least re-write on_msg_handle virtual function and handle messages in it; Create a service_pump object, create a server_base<your_socket> object, call service_pump::start_service; Call server_socket_base::send_msg or server_base::broadcast_msg when you have messages need to send.

client:

Derive your own socket from client_socket_base, you must at least re-write the on_msg or on_msg_handle virtual function and handle messages in it; Create a service_pump object, create a multi_client_base<your_socket> object, add some socket via multi_client_base::add_socket, call service_pump::start_service; Call client_socket_base::send_msg or multi_client_base::broadcast_msg when you have messages need to send.

Directory structure:

All source codes are placed in directory include, other directories hold demos, for documents, please refer to this project https://github.com/youngwolf-project/ascs/ .

Demos:

echo_server:

Demonstrate how to implement tcp servers, it cantains two servers, one is the simplest server (normal server), which just send characters from keyboard to all clients (from client demo), and receive messages from all clients (from client demo), then display them; the other is echo server, which send every received message from echo_client demo back.

client:

Demonstrate how to implement tcp client, it simply send characters from keyboard to normal server in echo_server, and receive messages from normal server in echo_server, then display them.

echo_client:

Used to test st_asio_wrapper's performance (whith echo server).

file_server:

A file transfer server.

file_client:

A file transfer client, use get <file name1> [file name2] [...] to fetch files from file_server.

udp_client:

Demonstrate how to implement UDP communication.

ssl_test:

Demonstrate how to implement TCP communication with ssl.

Compiler requirement:

No special limitations, just need you to compile boost successfully.

Boost requirement:

1.49 or highter.
