c++游戏服务端中使用configurator读取配置文件信息

c++游戏服务端中使用configurator读取配置文件信息

?????? 写游戏服务端时候我们通常都需要动态配置一下服务器信息，如数据库连结信息，游戏逻辑Socket信息，线程池大小等等。我们都写在一个配置文件在游戏服务器启动时候，读取该文件进行相应配置。有人喜欢用.ini方式配置文件，对于c++我更喜欢用Configurator框架读取。所以我先写一个配置文件game.conf:

//数据库连接信息
DbName????? : xxxGameDb
DbHost????? : 192.168.0.183
DbPort????? : 3306
DbUser????? : xxxGame
DbPassword? : xxxGame

?

//游戏服务器ip端口信息

<Server>
??? REMOTE_HOST? : 192.168.0.100
??? REMOTE_PORT? :? 443
????????????????
??? BDPOOL_CONNECTION_COUNT: 10
??? TASK_START_DETAL:?? 5000

??? StorePath?????? : /game/path/log??????????????????
??
??
??? ReconnectPeriod : 10
</Server>

#include <configurator/configurator.hpp>

#include <iostream>

?

//注册需要读取的配置项，即读该配置项信息，如果没有配置则使用default_value来配置

void register_options( cf::single_configurator& configurator ) {
??? configurator.add_option( "DbName" );
??? configurator.add_option( "DbHost" );
??? configurator.add_option( "DbPort" );
??? configurator.add_option( "DbUser" );
??? configurator.add_option( "DbPassword" );

??? configurator.in_section( "Server" );
??? configurator.add_option_here( "REMOTE_HOST" )?? .default_value( "127.0.0.1" )? .check_semanti( cf::ip )
??????????????? ;
??? configurator.add_option_here( "?REMOTE_PORT" )?? .default_value( 443)???? ;

??? configurator.add_option_here( "StorePath" )
??????????????? .check_semantic( cf::path );
??? configurator.add_option_here( "ReconnectPeriod" )
??????????????? .necessary();
