这是我们提供RPC的服务类：

class MprpcApplication
{
public:static void Init(int argc, char **argv);static MprpcApplication& GetInstance();static MprpcConfig& GetConfig();
private:static MprpcConfig m_config;MprpcApplication(){}MprpcApplication(const MprpcApplication&) = delete;MprpcApplication(MprpcApplication&&) = delete;
};

 在init操作中，我们加载配置文件，进行去除空格等操作

void MprpcApplication::Init(int argc, char **argv)
{if (argc < 2){ShowArgsHelp();exit(EXIT_FAILURE);}int c = 0;std::string config_file;while((c = getopt(argc, argv, "i:")) != -1){switch (c){case 'i':config_file = optarg;break;case '?':ShowArgsHelp();exit(EXIT_FAILURE);case ':':ShowArgsHelp();exit(EXIT_FAILURE);default:break;}}// 开始加载配置文件了 rpcserver_ip=  rpcserver_port   zookeeper_ip=  zookepper_port=m_config.LoadConfigFile(config_file.c_str());// std::cout << "rpcserverip:" << m_config.Load("rpcserverip") << std::endl;// std::cout << "rpcserverport:" << m_config.Load("rpcserverport") << std::endl;// std::cout << "zookeeperip:" << m_config.Load("zookeeperip") << std::endl;// std::cout << "zookeeperport:" << m_config.Load("zookeeperport") << std::endl;
}MprpcApplication& MprpcApplication::GetInstance()
{static MprpcApplication app;return app;
}MprpcConfig& MprpcApplication::GetConfig()
{return m_config;
}
