How to copy files between sites using REST API in SharePoint Online

Question

I have a file in a document library called images: https://xxx.sharepoint.com/Site1/Images

... and I would like to copy the file to the document library called backup in this site:

https://xxx.sharepoint.com/Site2/Backup

I would like to do this by using javascript and REST API. I have looked at this referance for the REST API: http://msdn.microsoft.com/en-us/library/office/dn450841(v=office.15).aspx#bk_FileCopyTo

I get the following error (translated, might not be exact): "There is no appcontext to perform the request"

My javascript looks like this:

function copy() {
    var executor = new SP.RequestExecutor('https://xxx.sharepoint.com/Site1/MyImages/');
    var url = "https://xxx.sharepoint.com/Site2/_api/SP.AppContextSite(@target)/web/getfilebyserverrelativeurl('/Site1/Images/1.jpg')/" +
        "/copyto(strnewurl='/Site2/Backup/1.jpg',boverwrite=false)" +
        "?@target='https://xxx.sharepoint.com/Site2/Backup/'";
    executor.executeAsync({
        url: url,
        method: "GET",
        success: successHandler,
        error: errorHandler
    });

    function successHandler() {
        console.log('success');
    };

    function errorHandler() {
        console.log('fail');
    };
}

Using SP.File.copyTo Method in REST endpoint, it is supported to copy files within a site only, for example:

executor.executeAsync({
  url: "<app web url>/_api/SP.AppContextSite(@target)/web
    /getfilebyserverrelativeurl('/Shared Documents/filename.docx')
    /copyto(strnewurl='/foldername/filename.docx',boverwrite=false)
    ?@target='<host web url>'",
  method: "POST",
  success: successHandler,
  error: errorHandler
});

where source file (/Shared Documents/filename.docx) and destination file (/foldername/filename.docx) are supposed to be located on the same site

Note: POST method is used for a CopyTo operation

Change source url and destination url before executing. On click on move button initListName() method can be called. Once SP.RequestExecutor.js is loaded Copy function can be done. This code can be used to copy files across site collection.

If copy is within site collection Function CopyTo can be directly used.

     var hostweburl="https://xxx.sharepoint.com";//edit

        function initListName() { 
          var scriptbase = hostweburl + "/_layouts/15/"; 
          $.getScript(scriptbase + "/SP.RequestExecutor.js", copyFile);
        }

        function copyFile() { 
          var sourceUrl=sourceUrlParam;//provide source site url
          var destUrl=destinatonUrlParam;//provide destination site url 
          // Create a request executor.
          var sourceExecutor = new  SP.RequestExecutor(sourceUrl); 
          var targetExecutor = new SP.RequestExecutor(destUrl); 
          var fileName="/sites/TestDemo/ProjectAttachments/Test%20123.docx";
         //provide file name with path 
       var fileContentUrl=sourceUrl+"/_api/web/GetFileByServerRelativeUrl('"+fileName+"')/$value";

        var targetSiteUrl=destUrl;

        //var folderName='ProjectAttachments';

        var newFileName="Test123.docx";//New name of added file
        var folderName="/sites/TestDemo/ProjectAttachments";
//provide folder path to which file to be copied
        var restUrl=targetSiteUrl+"/_api/web/GetFolderByServerRelativeUrl('"+folderName+"')/Files/Add(url='"+newFileName+"',overwrite=true)";

        $.ajax({
            url: targetSiteUrl + "/_api/contextinfo",
            type: "POST",
            headers: {
                "Accept": "application/json;odata=verbose"
            },
            success: function (data) {
                var digest = data.d.GetContextWebInformation.FormDigestValue;
                // Build executor action to retrieve the file data.
                var getFileAction = {
                    url: fileContentUrl,
                    method: "GET",
                    binaryStringResponseBody: true,
                    success: function (getFileData) {
                        // Get the binary data.
                        var result = data.body;
                        // Build executor action to copy the file data to the new location.
                        var copyFileAction = {
                            url: restUrl,
                            method: "POST",
                            headers: {
                                "Accept": "application/json; odata=verbose",
                                "X-RequestDigest": digest
                            },
                            contentType: "application/json;odata=verbose",
                            binaryStringRequestBody: true,
                            body: getFileData.body,
                            success: function(copyFileData) {
                            alert("successfully Copied");
                            },
                            error: function(ex) {
                            alert("Something went wrong, please try again later");
                                //show your 'failed' message
                            }
                        };

                        targetExecutor.executeAsync(copyFileAction);
                    },
                    error: function(ex) {
                        //fail
                        alert("Something went wrong, please try again later");
                    }
                };
                sourceExecutor.executeAsync(getFileAction);
            },
            error: function(ex) {
                //fail
                alert("Something went wrong, please try again later");
            }
