redisclient

Build status:

Current version: 0.4.4

Boost.asio based Redis-client header-only library. Simple but powerfull.

Get/set example:

#include <redisclient/redissyncclient.h>

int main(int, char **)
{
    boost::asio::ip::address address = boost::asio::ip::address::from_string("127.0.0.1");
    const unsigned short port = 6379;

    boost::asio::io_service ioService;
    RedisSyncClient redis(ioService);
    std::string errmsg;

    if( !redis.connect(address, port, errmsg) )
    {
        std::cerr << "Can't connect to redis: " << errmsg << std::endl;
        return EXIT_FAILURE;
    }

    RedisValue result;

    result = redis.command("SET", "key", "value");

    if( result.isError() )
    {
        std::cerr << "SET error: " << result.toString() << "\n";
        return EXIT_FAILURE;
    }

    result = redis.command("GET", "key");

    if( result.isOk() )
    {
        std::cout << "GET " << key << ": " << result.toString() << "\n";
        return EXIT_SUCCESS;
    }
    else
    {
        std::cerr << "GET error: " << result.toString() << "\n";
        return EXIT_FAILURE;
    }
}

Async get/set example:

#include <redisclient/redisasyncclient.h>

static const std::string redisKey = "unique-redis-key-example";
static const std::string redisValue = "unique-redis-value";

void handleConnected(boost::asio::io_service &ioService, RedisAsyncClient &redis,
        bool ok, const std::string &errmsg)
{
    if( ok )
    {
        redis.command("SET", redisKey, redisValue, [&](const RedisValue &v) {
            std::cerr << "SET: " << v.toString() << std::endl;

            redis.command("GET", redisKey, [&](const RedisValue &v) {
                std::cerr << "GET: " << v.toString() << std::endl;

                redis.command("DEL", redisKey, [&](const RedisValue &) {
                    ioService.stop();
                });
            });
        });
    }
    else
    {
        std::cerr << "Can't connect to redis: " << errmsg << std::endl;
    }
}

int main(int, char **)
{
    boost::asio::ip::address address = boost::asio::ip::address::from_string("127.0.0.1");
    const unsigned short port = 6379;

    boost::asio::io_service ioService;
    RedisAsyncClient redis(ioService);

    redis.asyncConnect(address, port,
            boost::bind(&handleConnected, boost::ref(ioService), boost::ref(redis), _1, _2));

    ioService.run();

    return 0;
}

Publish/subscribe example:

#include <redisclient/redisasyncclient.h>

static const std::string channelName = "unique-redis-channel-name-example";

void subscribeHandler(boost::asio::io_service &ioService, const std::vector<char> &buf)
{
    std::string msg(buf.begin(), buf.end());

    if( msg == "stop" )
        ioService.stop();
}

void publishHandler(RedisAsyncClient &publisher, const RedisValue &)
{
    publisher.publish(channelName, "First hello", [&](const RedisValue &) {
        publisher.publish(channelName, "Last hello", [&](const RedisValue &) {
            publisher.publish(channelName, "stop");
        });
    });
}

int main(int, char **)
{
    boost::asio::ip::address address = boost::asio::ip::address::from_string("127.0.0.1");
    const unsigned short port = 6379;

    boost::asio::io_service ioService;
    RedisAsyncClient publisher(ioService);
    RedisAsyncClient subscriber(ioService);

    publisher.asyncConnect(address, port, [&](bool status, const std::string &err)
    {
        if( !status )
        {
            std::cerr << "Can't connect to to redis" << err << std::endl;
        }
        else
        {
            subscriber.asyncConnect(address, port, [&](bool status, const std::string &err)
            {
                if( !status )
                {
                    std::cerr << "Can't connect to to redis" << err << std::endl;
                }
                else
                {
                    subscriber.subscribe(channelName,
                            boost::bind(&subscribeHandler, boost::ref(ioService), _1),
                            boost::bind(&publishHandler, boost::ref(publisher), _1));
                }
            });
        }
    });

    ioService.run();

    return 0;
}

Also you can build the library like a shared library. Just use -DREDIS_CLIENT_DYNLIB and -DREDIS_CLIENT_BUILD to build redisclient and -DREDIS_CLIENT_DYNLIB to build your project.
