我正在用poco测试redis客户机。如果注册psubscribe模式后发布，则不调用回调函数。
我正在用poco redis测试代码测试psubscribe。

class RedisSubscriber
{
public:
    void onMessage(const void* pSender, RedisEventArgs& args)
    {
     ...
    }

    void onError(const void* pSender, RedisEventArgs& args)
    {
      ...
    }
};

int main()
{
    std::string _host = "127.0.0.1";
    unsigned    _port = 6379;
    bool _connected;
    Poco::Redis::Client _redis;

    _redis.connect(_host, _port);

    RedisSubscriber subscriber;

    Array subscribe;
    subscribe.add("PSUBSCRIBE").add("hi*");

    _redis.execute<void>(subscribe);
    _redis.flush();

    AsyncReader reader(_redis);
    reader.redisResponse += Poco::delegate(&subscriber, &RedisSubscriber::onMessage);
    reader.redisException += Poco::delegate(&subscriber, &RedisSubscriber::onError);
    reader.start();

    std::cout << "Sleeping ..." << std::endl;
    while (true)
    {
        Poco::Thread::sleep(100);
    }   

...
    return 0;
}
