How to read redirected url parameters from Office.context.ui.displayDialogAsync

Question

I am stuck on how to read url parameters/token from redirected page url in Outlook web-addin. I am using DialogAPI to pop up my azure app sign-in/consent page and then trying to read tokens from redirected page.

I can see that token are passed but I couldn't figure out how to read token from url?

function GetToken(url)
{
_dlg = Office.context.ui.displayDialogAsync(url, { height: 40, width: 40 }, function (result) {
                _dlg = result.value;
                _dlg.addEventHandler(Office.EventType.DialogMessageReceived, processMessage);
                Office.context.ui.messageParent(somevalue);
            });

}

Besides that the processMessage call back never gets triggered, wondering why?

Guys any feedback would be helpful.

Thanks

Office.context.ui.displayDialogAsync must be called from the host page and Office.context.ui.messageParent must be called from the Dialog box.

This should be on the host page :

var dialog;    
Office.context.ui.displayDialogAsync(url,
    {height: 40, width: 40}, function (result) {
         dialog = result.value;
             dialog.addEventHandler(Office.EventType.DialogMessageReceived, 
                 function(somevalue){ 
                     console.log(somevalue);});
    });

This should be on the Dialog Box :

Office.initialize = function (reason) {
    $(document).ready(function () {
            Office.context.ui.messageParent(somevalue);
    }
}

in your manifest, must have all the domains being accessed with "https".

1. The URL uses the HTTPS protocol. This is mandatory for all pages loaded in a dialog box, not just the first page loaded.
2. The dialog box's domain is the same as the domain of the host page, which can be the page in a task pane or the function file of an add-in command. This is required: the page, controller method, or other resource that is passed to the displayDialogAsync method must be in the same domain as the host page.
