function getCurrentUserWithDetails()
{
    var endpointUrl = _spPageContextInfo.webServerRelativeUrl + '/_api/web/currentuser/?$expand=groups';
    return $.ajax({
            url: endpointUrl,
            method: "GET",
            contentType: "application/json;odata=verbose",

function getPagedItems(webUrl,listTitle,startItemId,itemsCount)
{
    var endpointUrl = webUrl + "/_api/web/lists/getbytitle('" + listTitle +  "')/items?$skiptoken=" + encodeURIComponent('Paged=TRUE&p_SortBehavior=0&p_ID=' + (startItemId-1) + '&$top=' + itemsCount);
    return executeRequest(endpointUrl,'GET');
}


getPagedItems('https://contoso.sharepoint.com/','Pages',2,2)
.done(function(data){
    if(data.d.results.length == 0){
        console.log('Items not found');
        return;
    }
    for(var i = 0; i < data.d.results.length; i++){
        var item = data.d.results[i];
        console.log(item.Title);
    }   
});

function uploadFileBinary() {
  var executor = new SP.RequestExecutor(appweburl);
  var body = "";
  for (var i = 0; i < 1000; i++) {
    var ch = i % 256;
    body = body + String.fromCharCode(ch);
