libfastcommon总结从文件中加载配置信息

Posted 2021-01-10 bin-dus

头文件为ini_file_reader.h

主要接口

　IniContext iniContext;//定义配置文件信息

    iniLoadFromFile();//加载文件为结构化配置信息
    iniGetStrValue();//根据key获取字符串值

　iniGetIntValue();//根据key获取int值

int main(){
    printf("begin
");
    IniContext iniContext;
    char full_filename[MAX_PATH_SIZE];
    int timeout = -1;
    int result = -1;
    char *webip=NULL;
    char *hostname=NULL;
    strcpy(full_filename,"test_conf.ini");
    if(!fileExists(full_filename)){
        printf("file is not exists!
");
        return 0;
    }
    if((result=iniLoadFromFile(full_filename,&iniContext))!=0){
        printf("load err!
");
        return result;
    }
    timeout = iniGetIntValue(NULL, "timeout",&iniContext, 0);
    printf("timeout = %d
",timeout);
    webip = iniGetStrValue(NULL, "www.baidu.com",&iniContext);
    printf("webip = %s
",webip);
    hostname = iniGetStrValue(NULL, "hostname",&iniContext);
    printf("hostname = %s
",hostname);
    iniFreeContext(&iniContext);
    printf("end
");
    return 0;
}

配置文件信息：

# define web‘s ip
www.baidu.com=192.168.1.1
# define hostname
hostname=webserver
# define timeout
timeout=180
# define loglevel
loglevel=3
