ajax post request is No 'Access-Control-Allow-Origin' header is present on the requested resource.'

I'm just making an ajax post request and I'm getting an error like:

XMLHttpRequest cannot load https://xxx.com?redirect_uri=http://www.example.com. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://example.com' is therefore not allowed access.

And here I can see there is nothing different from my response domain and request domain except "www", so does "www" also cause this issue?

When requesting data from external website it is always best to not do it in ajax , but if you have to do it an ajax have a internal page which makes a call with server side code and call that page with ajax.

The problem is because you are making a cross-domain AJAX request, which prevented by browser security - see the Same Origin Policy.

The request is expecting you to be making a request to a CORS enabled domain, hence why it is complaining about the non-existant header.

You either need to change your request to jsonp type, or use a server-side proxy to get the data.
