Upload large file

Create an upload session to allow your app to upload files up to the maximum file size.

C++ example

#include <iostream>
#include <fstream>

#include "independentsoft/graph/graph_client.hpp"
#include "independentsoft/graph/graph_exception.hpp"
#include "independentsoft/graph/upload_session.hpp"
#include "independentsoft/graph/files/drive_item.hpp"
#include "independentsoft/graph/files/drive_id.hpp"

using namespace independentsoft::graph;
using namespace independentsoft::graph::files;

int main()
{
    try
    {
        GraphClient client;

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

        UploadSession uploadSession = sync_wait(client.create_upload_session("/Folder1/Test.pdf", DriveId("b!T7ZW_FMzJ02x_G6HteZHZ")));

        std::ifstream fileStream("e:\\Test.pdf", std::ios::in | std::ios::binary);

        DriveItem item = sync_wait(client.upload_drive_item(uploadSession, fileStream));

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

    return 0;
}
