Export items

The following example shows you how to export mailbox items as EML/ICS files from a mailbox.

C++ example

#include <iostream>
#include <vector>
#include <string>
#include <fstream>

#include "independentsoft/graph/graph_client.hpp"
#include "independentsoft/graph/graph_exception.hpp"
#include "independentsoft/graph/mails/export_item_response.hpp"

using namespace independentsoft::graph;
using namespace independentsoft::graph::mails;

int main()
{
    try
    {
        GraphClient client;

        client.client_id = "63333333-209e-454e-b7bd-55a4d201270f";
        client.tenant = "independentsoft.onmicrosoft.com";
        client.client_secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

        std::vector<std::string> itemIds;
        itemIds.push_back("message-id-123");
        itemIds.push_back("message-id-456");

        std::vector<ExportItemResponse> exportedItems = sync_wait(client.export_items("mailbox-id-123", itemIds));

        for (std::size_t i = 0; i < exportedItems.size(); i++)
        {
            std::cout << "ItemId = " << exportedItems[i].item_id << std::endl;

            if (!exportedItems[i].data.empty())
            {
                std::ofstream out("item_" + std::to_string(i) + ".eml", std::ios::out | std::ios::binary);
                out.write(reinterpret_cast<const char*>(exportedItems[i].data.data()), static_cast<std::streamsize>(exportedItems[i].data.size()));
                std::cout << "Saved to item_" << i << ".eml" << std::endl;
            }

            std::cout << "" << std::endl;
        }
    }
    catch (const GraphException& ex)
    {
        std::cout << "Error: " << ex.code << std::endl;
        std::cout << "Message: " << ex.message << std::endl;
    }

    return 0;
}
