用提升精神解析複雜日誌

Question

我在用boost :: spirit解析複雜日誌時遇到問題。我無法按需要獲取數據，主要是因爲空白隊長將所有內容弄糟。

我有一個名爲log.txt的下一個文本文件：

1:[2017-Feb-18 01:57:55.341100] <INFO, SIMULATING> => CPU | Name: CAR (ID: 0) - ID: 1

20:[2017-Feb-18 01:58:33.386276] <INFO, SENDING_DATA> => PC | Send msg 7: 07010001F8B8C1AA 

，我使用的下一個代碼解析成一個提振融合適應結構：

#include <fstream> 

#include <boost/config/warning_disable.hpp> 
#include <boost/fusion/include/adapt_struct.hpp> 
#include <boost/spirit/include/qi.hpp> 
#include <boost/spirit/repository/include/qi_seek.hpp> 


struct Message 
{ 
    std::string line; 
    std::string date; 
    std::string time; 
    char id; 
    std::string hex; 
}; 

BOOST_FUSION_ADAPT_STRUCT(
    Message, 
    (std::string, Message::line) 
    (std::string, Message::date) 
    (std::string, Message::time) 
    (char, Message::id) 
    (std::string, Message::hex) 
) 

std::vector<Message> messages; 

namespace qi = boost::spirit::qi; 
namespace repo = boost::spirit::repository; 
namespace ascii = boost::spirit::ascii; 

void main() 
{ 
    std::ifstream in("C:/log.txt", std::ios_base::in); 
    in >> std::noskipws;//No white space skipping 

    if (!in) 
    { 
     std::cerr << "Error: Could not open input file: " << std::endl; 
     return; 
    }//if 

    boost::spirit::istream_iterator first(in); 
    boost::spirit::istream_iterator last; 

    bool result = qi::phrase_parse(first, last, 
     *repo::seek[qi::eol 
      >> +ascii::char_("0-9") 
      >> ":[" 
      >> +ascii::char_("0-9a-fA-F-") 
      >> +ascii::char_("0-9.:") 
      >> "] <INFO, RECEIVING_DATA> => PC" 
      >> ascii::char_('1', '2') 
      >> "| Receive msg 6:" 
      >> +ascii::char_("0-9a-fA-F") 
      >> qi::eol], 
     ascii::blank, 
     messages); 

    return; 
} 

當執行代碼，數據在結構中格式不正確。有人可能試圖幫助我解決這個問題嗎？

Answer 1

我加了lexeme後，我能夠解析下面一行日誌文件：

14:[2017-Feb-18 01:58:32.206208] <INFO, RECEIVING_DATA> => PC1 | Receive msg 6: 06010001F8B8C1A8 

這是我的代碼。它仍然沒有閱讀原始log.txt。但我不確定你想要達到的目標。

#include <fstream> 

#include <boost/config/warning_disable.hpp> 
#include <boost/fusion/include/adapt_struct.hpp> 
#include <boost/spirit/include/qi.hpp> 
#include <boost/spirit/repository/include/qi_seek.hpp> 
#include <boost/spirit/include/phoenix.hpp> 
#include <boost/spirit/include/phoenix_operator.hpp> 

struct Message 
{ 
    std::string line; 
    std::string date; 
    std::string time; 
    char id; 
    std::string hex; 
}; 

BOOST_FUSION_ADAPT_STRUCT(
    Message, 
    (std::string, Message::line) 
    (std::string, Message::date) 
    (std::string, Message::time) 
    (char, Message::id) 
    (std::string, Message::hex) 
) 

std::vector<Message> messages; 

namespace qi = boost::spirit::qi; 
namespace repo = boost::spirit::repository; 
namespace ascii = boost::spirit::ascii; 
namespace ph=boost::phoenix; 

void main() 
{ 
    std::ifstream in("C:/temp/log2.txt", std::ios_base::in); 
    in >> std::noskipws;//No white space skipping 

    if (!in) 
    { 
     std::cerr << "Error: Could not open input file: " << std::endl; 
     return; 
    }//if 
    Message msg; 
    boost::spirit::istream_iterator first(in); 
    boost::spirit::istream_iterator last; 
    bool result = qi::phrase_parse(first, last, 
//  *repo::seek[ 
     (+ascii::char_("0-9") 
     >> qi::lexeme[":[" >> +ascii::char_("0-9a-fA-F-")] 
     >> +ascii::char_("0-9.:") 
     >> "] <INFO, RECEIVING_DATA> => PC" 
     >> ascii::char_('1', '2') 
     >> "| Receive msg 6:" 
     >> +ascii::char_("0-9a-fA-F")) 
     % qi::eol, 
/*  >> qi::eol],*/ 
     ascii::blank, 
     messages); 
     for (auto msg : messages) { 
      std::cout << msg.line << ", " << msg.date << ", " << msg.time << ", " << msg.id << ", " << msg.hex << std::endl; 
     } 
    return; 
}
