如何使用此代码打印时间，日期，当前功能？ [英] How to print time, date, current function using this code?

问题描述

我有示例Boost Logger代码，当执行此代码时，我得到这样的输出

输出：

1：60：line_number.cpp：< debug>



如何得到这样的输出：

执行输出：

1：< time，date> line_number.cpp：< current_function> < debug>



1：2014-Jul-15 10：47：26.137959 line_number.cpp：Main.cpp< debug>







任何人都可以帮助我，我是新手来提升记录器。



我尝试过：

I had sample Boost Logger code,when Execute this code, I got output like this
output:
1: 60: line_number.cpp: <debug>

How to get output like this:
Execpting output:
1:<time,date> line_number.cpp: <current_function> <debug>

1:2014-Jul-15 10:47:26.137959 line_number.cpp: Main.cpp <debug>



Can anyone help me,I am new to boost logger.

What I have tried:

#include <ostream>
#include <fstream>
#include <boost/log/core.hpp>
#include <boost/log/trivial.hpp>
#include <boost/log/sinks/sync_frontend.hpp>
#include <boost/log/sinks/text_ostream_backend.hpp>
#include <boost/log/utility/setup/common_attributes.hpp>
#include <boost/log/utility/manipulators/add_value.hpp>
#include <boost/filesystem.hpp>

namespace logging = boost::log;
namespace src = boost::log::sources;
namespace expr = boost::log::expressions;
namespace sinks = boost::log::sinks;

void my_formatter(logging::record_view const& rec, logging::formatting_ostream& strm)
{
    // Get the LineID attribute value and put it into the stream
    strm << logging::extract< unsigned int >("LineID", rec) << ": ";

	 strm << logging::extract< unsigned int >("TimeStamp", rec) << ": ";
    strm << logging::extract< int >("Line", rec) << ": ";
    logging::value_ref< std::string > fullpath = logging::extract< std::string >("File", rec);
    strm << boost::filesystem::path(fullpath.get()).filename().string() << ": ";

    // The same for the severity level.
    // The simplified syntax is possible if attribute keywords are used.
    strm << "<" << rec[logging::trivial::severity] << "> ";

    // Finally, put the record message to the stream
    strm << rec[expr::smessage];
}

void init()
{
    typedef sinks::synchronous_sink< sinks::text_ostream_backend > text_sink;
    boost::shared_ptr< text_sink > sink = boost::make_shared< text_sink >();

    sink->locked_backend()->add_stream(
        boost::make_shared< std::ofstream >("sample2333.log"));

    sink->set_formatter(&my_formatter);

    logging::core::get()->add_sink(sink);
}

#define MY_GLOBAL_LOGGER(log_,sv) BOOST_LOG_SEV( log_, sv) \
  << boost::log::add_value("Line", __LINE__)      \
  << boost::log::add_value("File", __FILE__)       \
  << boost::log::add_value("Function", BOOST_CURRENT_FUNCTION)  \
  

int main(int, char*[])
{
    init();
    logging::add_common_attributes();

    using namespace logging::trivial;
    src::severity_logger< severity_level > lg;

    MY_GLOBAL_LOGGER(lg,debug) << "Sample";
    MY_GLOBAL_LOGGER(lg,info) << "Critical";
    MY_GLOBAL_LOGGER(lg,warning) << "Simple";
    MY_GLOBAL_LOGGER(lg,error) << "Hello";
	system("pause");
    return 0;
}

推荐答案

使用时间函数（Windows） [ ^ ]，并将结果添加到您的日志记录中。

Use whichever of the Time Functions (Windows)[^] you need, and add the result to your logging.
