请用C++写一份动态链接库读配置项精确判断年月日时分秒用户时间是否过期

#include #include #include

extern "C" { bool isExpired(const std::string& expireDateStr, const std::string& expireTimeStr) { // Get current date and time std::time_t currentTime = std::time(nullptr); std::tm* localTime = std::localtime(&currentTime);

    // Parse the expiration date and time
    std::tm expireTime = {};
    if (sscanf(expireDateStr.c_str(), "%d-%d-%d", &expireTime.tm_year, &expireTime.tm_mon, &expireTime.tm_mday) != 3)
        return false;
    if (sscanf(expireTimeStr.c_str(), "%d:%d:%d", &expireTime.tm_hour, &expireTime.tm_min, &expireTime.tm_sec) != 3)
        return false;
    expireTime.tm_year -= 1900; // Adjust year
    expireTime.tm_mon -= 1; // Adjust month

    // Check if current time is after expiration time
    std::time_t expireTimestamp = std::mktime(&expireTime);
    return currentTime > expireTimestamp;
}
