问题描述
我有一个问题使用 boost :: archive :: binary_oarchive
。当执行程序时,我得到程序崩溃时实例化 ia>> boost :: serialization :: make_binary_object(buffer,size)
。
使用 boost :: archive :: text_oarchive
它工作...
I have a problem using boost::archive::binary_oarchive
. When executing the program I get a program crash when instantiating the ia >> boost::serialization::make_binary_object(buffer, size)
.
With boost::archive::text_oarchive
it works...
#include <boost/archive/binary_oarchive.hpp>
#include <boost/archive/binary_iarchive.hpp>
#include <boost/serialization/string.hpp>
#include <boost/serialization/binary_object.hpp>
#include <iostream>
#include <fstream>
using namespace std;
void save()
{
size_t size = 0;
std::ifstream infile("any_file.png", std::ios::in | std::ios::binary | std::ios::ate);
if (infile.is_open())
{
size = infile.tellg();
char *buffer = new char[size];
infile.seekg(0, ios::beg);
infile.read(buffer, size);
infile.close();
std::ofstream file("archiv.bin");
boost::archive::binary_oarchive oa(file);
oa << size;
oa << boost::serialization::make_binary_object(buffer, size);
file.close();
delete [] buffer;
}
}
void load()
{
size_t size = 0;
std::ifstream file("archiv.bin");
boost::archive::binary_iarchive ia(file);
ia >> size;
char *buffer = new char[size];
ia >> boost::serialization::make_binary_object(buffer, size); //program crash
file.close();
ofstream outfile("any_file_out.png", ios::out | ios::binary);
for(size_t i = 0; i < size; i++)
{
outfile << buffer[i];
}
outfile.close();
delete [] buffer;
}
int main()
{
save();
load();
return 0;
}
提前感谢!
编辑:
这是它的工作原理。
This is how it works.
...
std::ofstream file("archiv.bin", ios_base::binary);
...
std::ifstream file("archiv.bin", ios_base::binary);
...
推荐答案
:)
...
std::ofstream file("archiv.bin", ios_base::binary);
...
std::ifstream file("archiv.bin", ios_base::binary);
...
现在可以完美工作了!
