如何将带有模板"%d.%m.%Y %H:%M:%S"
的字符串(例如, 28.05.2013 17:42:00 )转换为boost::posix_time::ptime
或类似内容?
以下是我的非工作代码。
boost::posix_time::ptime stringToDateTime(const std::string &text) {
const std::locale fct
( std::locale::classic()
, new boost::gregorian::date_input_facet("%d.%m.%Y %H:%M:%S")
);
std::istringstream is(text);
is.imbue(fct);
boost::posix_time::ptime date;
is >> date;
return date;
}

有一种丑陋的方式我不接受
boost::posix_time::ptime stringToDateTime(const std::string &text) {
return boost::posix_time::time_from_string
( text.substr(6, 4) // year
+ "-"
+ text.substr(3, 2) // month
+ "-"
+ text.substr(0, 2) // day
+ text.substr(10, 9) // hour,min,sec
);
}

boost::posix_time::ptime stringToDateTime(const std::string &text) {
const std::locale fct
( std::locale::classic()
, new boost::posix_time::time_input_facet("%d.%m.%Y %H:%M:%S")
); //^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - that was an error
std::istringstream is(text);
is.imbue(fct);
boost::posix_time::ptime date;
is >> date;
return date;
}
