uv-cpp

Language Translations:

uv-cpp is a simple interface, high-performance network library based on C++11.

Dependencies

libuv

Features

C++11 functional/bind style callback instead of C-style function pointer.
TCP and UDP wrapper.
DNSandHttp：DNS query and http support，Http routing based on radix tree.
TimerandTimerWheel：Heartbeat timeout judgment with time complexity of O(1).
Async：libuv async wrapper，but optimized the problem of calling multiple times but callback will only be called once.
PacketandPacketBuffer：Send and receive packet of Tcp data stream. Support custom data packet structure (such as uvnsq)
Log interface.

Quick start

A simple echo server

#include <iostream>
#include <uv/include/uv11.h>

int main(int argc, char** args)
{
    uv::EventLoop* loop = uv::EventLoop::DefaultLoop();
	
    uv::TcpServer server(loop);
    server.setMessageCallback([](uv::TcpConnectionPtr ptr,const char* data, ssize_t size)
    {
        ptr->write(data, size, nullptr);
    });
    //server.setTimeout(60); //heartbeat timeout.
	
    uv::SocketAddr addr("0.0.0.0", 10005, uv::SocketAddr::Ipv4);
    server.bindAndListen(addr);
    loop->run();
}

A simple http service router which based on radix tree.

int main(int argc, char** args)
{
    uv::EventLoop loop;
    uv::http::HttpServer::SetBufferMode(uv::GlobalConfig::BufferMode::CycleBuffer);

    uv::http::HttpServer server(&loop);
	
    //example:  127.0.0.1:10010/test
    server.Get("/test",std::bind(&func1,std::placeholders::_1,std::placeholders::_2));
    
    //example:  127.0.0.1:10010/some123abc
    server.Get("/some*",std::bind(&func2, std::placeholders::_1, std::placeholders::_2));
    
    //example:  127.0.0.1:10010/value:1234
    server.Get("/value:",std::bind(&func3, std::placeholders::_1, std::placeholders::_2));
    
    //example:  127.0.0.1:10010/sum?param1=100&param2=23
    server.Get("/sum",std::bind(&func4, std::placeholders::_1, std::placeholders::_2));
    
    uv::SocketAddr addr("127.0.0.1", 10010);
    server.bindAndListen(addr);
    loop.run();
}
