参考链接：cout重定向到文件（转）
关于如何将cout的内容输出到文件一直不知怎么处理，在学习了该文章后，实现了我想要的功能。

代码贴出如下：
Log.h:

#ifndef LOG_H#define LOG_H#include<ctime>#include<fstream>#include<iostream>#include<sstream>#include<string>using namespace std;class Log{    ofstream of;    struct tm* nowtime;    time_t now;    string loginfo;    streambuf* fileBuf;    int year;    int mon;    int day;    int hour;    int min;    int sec;    stringstream itos;    string s_time;    const char* logname;public:    log(const string& str,const char* log_name);    ~Log();    void getTime();    ofstream& Debug();};#endif

Log.cpp:

#include "Log.h"Log::Log(const string& str,const char* log_name):loginfo(str),    logname(log_name){    of.open(logname,ios::app);    fileBuf = of.rdbuf();    getTime();    cout.rdbuf(fileBuf);    cout<<s_time<<"||"<<loginfo<<"||\t---------Log Begin----------"<<endl;    of.flush();}void getTime(){    time(&now);    nowtime = localtime(&now);    year = nowtime->tm_year + 1900;    mon = nowtime->tm_mon + 1;    day = nowtime->tm_mday;    hour = nowtime->tm_hour;    min = nowtime->tm_min;    sec = nowtime->tm_sec;    itos << year << "-" << mon << "-" << day     << "," <<hour<<":"<<min<<":"<<sec;    itos >> s_time;}ofstream& Log::Debug(){    getTime();    cout<<s_time<<"||"<<loginfo<<"||DEBUG||\t";    of.flush();    return of;}Log::~Log(){    of.close();}
