simple program to save file from c++ to (mongodb) gridfs

MongoDB C++ Tutorial http://www.mongodb.org/pages/viewpage.action?pageId=133415


The best start is building MongoDB from source (Ubuntu|Debian).

$sudo apt-get install g++ scons libpcre++-dev libmozjs-dev libpcap-dev libboost-dev
$cd /usr/src
$sudo git clone git://github.com/mongodb/mongo.git
$cd mongodb
$scons
$scons --prefix=/opt/mongo install
$cd ~
$gvim test_gridfs.cpp

#include <iostream> 
#include <vector>

#include <boost/algorithm/string.hpp>

#include <mongo/client/dbclient.h>
#include <mongo/client/gridfs.h>

// g++ tutorial.cpp -lmongoclient -lboost_thread -lboost_filesystem -o tutorial

using namespace std;
using namespace mongo;

int main(int argc, const char **argv) { 
const char *fileName = "";
std::vector<std::string> strs;

if (argc != 2) {
cerr << "Usage " << argv[0] << " local_file "  << endl; 
      return -12;
   }

   fileName = argv[1];
   //to generate gridfs file name
   boost::split(strs, fileName, boost::is_any_of("/"));

   DBClientConnection c;
   c.connect("localhost"); 
   cout << "connected ok" <<endl;

   GridFS gfs = GridFS(c, "test", "testcpp");
   gfs.storeFile(fileName, strs[strs.size()-1]);
   cout << "file stored" << endl;

   return 0;
}
