Question

I am trying to revoke a token using the Google Api client side code.

My code looks something like this:

$.get("https://accounts.google.com/o/oauth2/revoke?token=" + accessToken, function () {
        window.location.reload();
    }); 

And I am getting the following error?

XMLHttpRequest cannot load
https://accounts.google.com/o/oauth2/revoke?token=tokenishere Origin
http://balblabla.com is not allowed by Access-Control-Allow-Origin.

Following on from @krg’s comment:

Based on the error it looks like you cannot do this on this client. Perhaps you’ll need a server-side script to handle the request from within your domain. You can also explore this solution. Here’s a jsFiddle example using the solution.

I have done this on the server side, using the same code:

$.ajax({
     url:"https://accounts.google.com/o/oauth2/revoke?token=10100101",
     dataType: 'jsonp', // Notice! JSONP <-- P (lowercase)
     success:function(json){
         console.log(arguments);
         // do stuff with json (in this case an array)
         alert("Success");
     },
     error:function(){
         alert("Error");
     },
});

which works.
